Many electric skateboard companies still use Lead Acid (SLA) batteries, but their excessive weight, short cycle life, low power output, and outdated technology make them far inferior to Metroboard’s High Power Lithium (LiFePO4) batteries. While SLA batteries are far cheaper than LiFePO4, these big and heavy batteries significantly add to the overall weight, and in some cases the boards reach upwards of 50 lbs. When it comes to cycle life, SLA batteries pale in comparison to LiFePO4, which have approximately 13 times the number of recharge cycles! SLA batteries are large and cumbersome, and in most instances extend so far from the board that they almost touch the ground. Yes, LiFePO4 batteries cost more up front, but in the long run they not only save you money compared to SLA batteries, but they also provide more power, less weight, and less size.
LiFePO4 batteries are some of the heaviest and most expensive lithium batteries, but are also the safest and longest lasting. Now that we’ve got the summary of different types of lithium batteries out of the way, lets look at how these lithium batteries stack up as a whole.
Lithium batteries made specially for ebikes often come with specific bicycle mounting points making them easy to bolt to the bike frame, seat post or rear rack. Lithium batteries are also small enough to allow you to place your batteries pretty much anywhere on your bike. Lithium batteries (with the exception of RC LiPos) last much longer than lead acid batteries. A big downside of lithium batteries is that they are much more expensive than lead acid batteries.
However, when you factor in the shorter life cycle of lead acid batteries, they become comparable to lithium batteries over the entire life of the electric bicycle.
One other disadvantage of lithium batteries that isn’t talked about often, but should be, is their potential for theft.
Most lithium batteries that are designed to mount to ebikes also come with some form of locking system.
For this reason I like to either add a second lock specifically through the handle of my lithium battery (if it’s a removable style battery) or permanently secure it to the bike so it isn’t removable at all. When it comes to lead acid batteries for ebike use, you’ll generally be looking for what’s called a “sealed lead acid” or SLA battery. Lead acid batteries are much larger and heavier than lithium batteries, limiting their placement on ebikes.
When I’m experimenting with some new ebike parts and want to test different battery voltages for different speeds, I often use lead acid batteries because I can try many different voltages using very cheap batteries. The exact amount of range you’ll get per battery and motor varies greatly and depends on factors like terrain, speed, weight, etc. Lead acid batteries, on the other hand, seem to have been dismissed out of hand as a parade of new energy storage products pile into the Australian market.
It’s also worth noting that lead acid batteries do not have the same sort of freight safety restrictions that lithium-ion batteries do, meaning there are fewer hurdles when it comes to importing them to Australia. Secondly, the UltraBattery is capable of impressive feats of instantaneous power output, when required. The UltraBattery is stores and discharges energy significantly more efficiently than a conventional valve-regulated lead acid (VRLA) battery – especially at partial states of charge. The UltraBattery retains its ability to hold a charge much better than VRLA when operating at partial state of charge over the course of its lifetime.
On the back of its success in these fields, Ecoult is delving into smaller-scale applications, recently introducing a 29 kilowatt-hour nominal (kWh) battery bank for small-scale commercial applications. Hello, I currently have a stand alone solar system with a wet lead acid battery bank with 33 kilowatt hour storage capacity.
I’ve reached out to Ecoult directly with your enquiry and they should be in touch with you with a response soon.
If you’re considering options other than the Ecoult battery, you can request a battery storage quote comparison through our site by filling out the Quote Comparison request form to the right of this page.

When it’s time for a new set of batteries in your golf car, lithium sounds like a good alternative for many of the popular reasons, including no maintenance and a seemingly environmentally friendly footprint. The facts are that lithium batteries require a new charger and a Battery Monitoring System, an on-board computer known as a BMS. With operational costs being a major concern for anyone with a golf car fleet, it’s important to point out that there is the initial cost of a lithium iron phosphate pack (LiFePO4), plus the required additional equipment necessary to operate it.
When comparing the costs, (see the chart below) you can see that for a 48-volt pack, you can buy four 12-volt lead-acid batteries for about $640 retail.


Lithium batteries are also touted as the “green” alternative to lead-acid because they do not contain lead or corrosive materials.
For golf courses and golf car fleets intent on lowering operating costs, it’s clear that lead-acid batteries remain the best choice because of their lower operating cost, proven track record, and a great recycling system that produces a small environmental footprint. The chart demonstrates the direct cost comparison between lithium and FLA batteries as they pertain to the golf car industry and the voltage vs amp-hour requirements. It was some eighteen months ago, that PSA Peugeot-Citroen unveiled its first hybrid-air concept, a Citroen C3. Some car manufacturers have forgotten it, but there’s no better way to reduce fuel consumption than to reduce weight. This means you can use your Metroboard year after year without having to worry about doling out hundreds of dollars to swap out the battery. These high tech cells offer high power performance throughout the entirety of their charge, even when the battery is ? depleted. LiFePO4 batteries are the best choice for high end electric skateboards, and that’s why Metroboard has chosen them as our standard battery of choice. Sure, there are a few other types of ebike batteries out there, but the main two types you’ll see all over the place remain lithium and lead acid. I’ll give a short summary of the different types of electric bicycle specific lithium batteries here, but you can get a more detailed description as well as the pros and cons of each type of lithium battery in my article Not All Lithium Batteries Were Created Equal.
Their disadvantages include short lifespan and propensity to combust into giant fireballs if not cared for correctly (I’m not kidding, check out the short video clip below). If you go with a different type of lithium battery without ebike specific mounts, you’ll likely have to put it in a bag on the bike, which is still a good option, and one that I even prefer sometimes.
This is especially true for people who want to assemble their own pack or use heat shrink wrapped lithium batteries instead of hard case lithium batteries with prefabricated bicycle frame mounts. Prices vary depending on the voltage and capacity of the lithium battery, but standard ebikes usually have lithium batteries starting in the $300 range and rising quickly from there. For example, a lithium battery may cost five times the price of a lead acid battery, but it could easily last five times as long as well, making the price about the same over the life of the lithium battery.
Lithium ebike batteries have become huge targets by bike thieves as a result of their combination of small size and high price tags (the same factors that keep shaving razor cartridges behind lock and key at the drug store).
The second option is less convenient because it means you have to bring the charger to the ebike, but it’s a much more secure option if you find yourself locking your ebike in public often.
SLAs come sealed in a hard plastic case and can be turned in any orientation safely without leaking acid.
They almost never come packaged with ebike specific mounting hardware which means that they generally have to go in a bag on the rear rack or in panniers on either side if the rear wheel. Lead acid batteries can be purchased from many different online retailers and local stores.
There’s no beating around the bush here, SLAs are HEAVY, as you might guess by the inclusion of “lead” in the name. Most claim to be rated for over 200 cycles, but in practice I usually find many SLAs start showing their age at around 100 cycles. This can be both an advantage and disadvantage; it gives you more room for customization but requires some work to combine the individual SLA batteries together into a larger pack. Of course, for your specific ebike you might have other reasons that could sway you either way. He's spent the better part of a decade working in the electric bicycle industry, and is the author of The Ultimate DIY Ebike Guide. Suffice it to say though that if you double your current battery capacity, you’ll see an approximate doubling of your range as well. If you want to support this site and help me keep it free, consider checking out my ebook and video course on building ebikes. Already deployed in a number of grid-support and industrial applications, the company is also aiming to bring the UltraBattery into homes and small businesses in the near future. This means that more of the energy stored within the battery is actually accessible for regular use – and for a much longer period of time. Contrast this with conventional lead acid batteries, which struggle to satisfy high power demand (e.g. All of these facts about the UltraBattery knock back the conventional wisdom that lead acid batteries are fragile and must be treated delicately in order to extend their lifespan. By doing so you’ll be able to compare a range of storage options (and prices) from installers in your area.
But for many other industrial applications, like in the golf car industry, lithium doesn’t always add up.


Taking a closer look, however, we can see that switching to lithium in golf cars, is not limited to simply swapping out a set of batteries.
The BMS monitors each cell individually and regulates charge and discharge for cell balancing and safety.
A single LiFePO4 cell has a nominal voltage of 3.2 volts, thus requiring 15 cells in series for a 48-volt pack. That will get you around 150 Ahr and 750 or more cycles with no additional equipment needed. The facts are, however, that lead-acid golf car batteries are recycled at a rate of 97-99 percent, with the recycled lead going back into new golf car batteries, not the environment.
For additional information on deep-cycle flooded lead-acid batteries for golf car and other industrial uses, visit U.S. Compare that to the LiFePO4 batteries used in Metroboard electric skateboards, which weigh in at as little as 15 lbs, and it’s easy to see that bigger doesn’t necessarily mean better. This efficiency allows you to quickly accelerate and power up hills from the beginning of your ride to the end. Of course lithium batteries and lead acid batteries each come with their own distinct advantages and disadvantages, and knowing the difference will help you decide which is best for your ebike. You’d have to buy at least four replacement lead acid batteries (maybe even more) by the time your lithium battery finally kicks the can. Thieves see an easy target and ample resale market, meaning you have to be extra careful about locking your ebike up and leaving it alone in public. The type with a little pin that slides into a thin sheet of steel are the easiest to steal by mangling the thin steel locking plate. Mounting them up high on the rack isn’t a good idea either because it will negatively affect handling. They’ll still work as they get up in years (or charge cycles), but you’ll begin seeing your range quickly decreasing. Micah can usually be found riding his electric bicycles around Florida, Tel Aviv, and anywhere else his ebikes wind up.
Partially discharging then recharging traditional lead acid batteries repeatedly on a regular basis has detrimental impacts on their longevity and overall efficiency; this is not an issue with most of their lithium-ion counterparts. The UltraBattery is clearly much more robust in demanding environments than flooded and VRLA batteries. I don’t know exactly where Ecoult sits on this scale, but they would argue that the thing to look at would be the long-term value of the energy instead. The BMS must communicate with a charger that is capable of reading the BMS communication protocol. The average retail price of one 100 Ahr (amp-hour) cell is $155, putting the pack cost at $2325. Overall, the flooded lead-acid battery pack will deliver more energy per cycle at a lower cost per kilowatt-hour on each cycle by a factor of over 3:1. The recycling infrastructure of lead-acid batteries is a closed loop process that more than pays for itself, while recycled lithium rarely goes back into new batteries due to the high cost of recycling. Two or three mid to large capacity lithium batteries could easily fit on one ebike, giving potential ranges of 100 miles (160 km) or more. Wet cell lead acid batteries, like many car batteries, would leak dangerous acid if turned on their side or upside down, making them a bad idea for use on an electric bicycle, which is a lot more likely to get knocked over than a car. Generally speaking, you want to mount your batteries as low as possible to keep the center of gravity of the ebike lower towards the ground. If you are planning a very high power electric bicycles, SLAs might be a good option for you. You should also be aware that lugging that extra weight around is going to negatively impact your range. If you were traveling 15 miles per charge when the SLAs were new, a year later you could find yourself barely getting past 10 miles. The best way to improve the range of any electric vehicle is to reduce weight, and SLAs are kind of going the opposite way in that regard. Thanks to its hybrid nature, the UltraBattery can also be occasionally discharged 100% in order to support critical events, meaning that on top of performing its normal daily application, supplying even more energy when it is needed most – for example, in the event of a grid blackout.
Altogether, a conversion would cost $3690 and will provide a reported 2000 cycles at a lower energy content of 4800 watt-hours vs 7200 watt-hours for a comparable flooded lead-acid battery pack.
