    • UPDATE*******So far I'm impressed. Very impressed. ****See Note****
Size: 12V 12Ah-2PACK
A few weeks in, and 5 stars isn't enough. Everything I say below, and more. I've only charged these things a few times now, whereas with the SLA, I'd have to worry about topping off, or doing a maintenance cycle, which only seemed to kill them faster. These just perform. My range has increased significantly, but I don't have actual measurements. I reflexively look at my battery gauge, but I'm always surprised that I still have charge. I think the primary reason for the range increase is weight. These things feel like air compared to my old batteries. please read my original review below*** ***I bought these to replace the batteries in my Pride G0-Chair. I've been through 3 sets of the "Recommended SLA" batteries from the manufacturer, in three years. I don't use my chair every day, but when I do, I'm usually pretty hard on it. That said, the last set, which I bought from Interstate battery directly, only lasted mere 8 months. I was down to about .3 of a mile before charging, when the specifications list 8+ miles per charge. Though these come out to only 2/3 the original capacity, (12Ah vs. 18Ah) I was able to travel over 5 miles over 4 days on a single charge. I wanted to test the built in BMS's, and I also decided to order a charger specific to 24V, so I didn't charge it. The BMS safety kicked in and shut down my chair at my neighbors house. THIS IS NOT A NEGATIIVE!!!!! Regular SLA or AGM will let you discharge them to death.... literally. The protection worked as hoped, and as a bonus, I confirmed that the battery gauge is "close enough" to read these. If it starts blinking red on the controller, get to an outlet, or get home quick. The BMS doesn't play. I will say, they hold the green far longer, and once your into the yellow, they do fall off faster than I expected, but that is the nature of Lithium vs. lead acid. These do not fit my battery box , but I knew that going in. However, I am going to modify the box, and given the space, I will be able to install the charger on board. Which brings me to my final point. These things are LIGHT. I mean feather weight in comparison to the SLA/AGM batteries they replaced. Even if they matched in size and capacity, I can't imagine them weighing much more. They are literally about 1/4 the weight. The entire battery box weighs less now, than just one of the old batteries by itself. ****NOTE**** I had to change the terminal connections and am making modifications to my chair to accommodate these batteries, and have a good understanding of electronics, and electrical and charging systems. I used to build defibrillator's for the medical industry. Do this at your own risk!!! Even though it says you can use an SLA charger, I recommend a 29.2 volt charger specifically for LifePo4 batteries, if you are on a 24v system like I am. Last word: These are light, powerful, and charge relatively quickly at the recommended 5 Amps. Because they are so light, I plan to build a second "backup" for extended range. Even 4 of these only weigh as much as one of my old batteries. If anything changes, I will update. **Update** Okay, still 5 stars. Wish I could give 6. On my second charge cycle, and even more impressed. I don't know about longevity yet, but given my initial experience, and if they last even close to the specified number of charge cycles, these batteries will actually outlive me. ... show more

Review Image by AMO AMO
Updating my review to 5 stars: It turns out the batteries were not bad at all. It was a blown fuse in the battery compartment which linked all (4) batteries in series. Once I replaced the fuse the batteries all worked fine. So the repair shop I took my scooter to didn't bother opening up the battery box to examine it and just assumed all the batteries were bad since there was no power coming from the battery box. After I wrote to the company which sold me the batteries through Amazon messaging. They replied that they would refund me for the (4) batteries. I did not take them up on their refund because I wanted to test/charge each battery up individually instead of trying to charge them all through the battery box in series. They charged up fine individually. That's when I noticed a small round container with a twist off top instead the battery box. It contained a fuse. After replacing the F30A250V fuse the battery box was able to charge up all 4 batteries and plugging it into my scooter worked fine. [Original 1 star review] Purchased (4) of the Nermak 12V 12AH lithium batteries for an old electric sit on scooter. Used 3 times in 5 months and the last time I used I hit a small bump in the road and the scooter stopped working. I thought my scooter's wiring was faulty so brought it into a repair shop. They tried to charge the batteries but said they see 0 voltage coming from the batteries and recommended me to replace the batteries. The other 2 times I rode the scooter I got stranded because the batteries died. Again I thought it was a mechanical/electrical problem. But it was able to start back up after charging the batteries. Since the 30 day return policy has long passed and don't know how to contact "Nermak" since they only seem to sell through Amazon I am out of luck with getting new/working batteries to replace these duds. All 4 batteries... Wow! ... show more

    • Don’t buy!! Expensive and die after a year!
Size: 12V 12Ah-2PACK
While these batteries are light, they are twice the price of lead acid, and last half as long. I purchased the batteries about a year ago and use it in a UPS that is always pluged in. The power rarely flickers or goes out. However when a storm came through and the lights flickered the batteries failed, and now won’t hold any charge. Replaced with normal lead acid and UPS works fine. Save your money and buy another battery unless you want to replace ever 6-12 months. ... show more

    • I was wrong!
Size: 12V 12Ah
EDIT: It looks like I made a mistake! I have very little experience with battery systems, so I'm sort of still experimenting. I had bought a battery monitor, and had one of the settings (# of cells) set incorrectly. After changing that setting, and charging the battery back to 100% it looks like it's holding just fine. Time will tell. The battery was well outside of the return window, but the seller reached out to me after my original review and offered to refund my money. That says a lot to me. I did not accept their offer. I think that the battery is fine. Lifepo4 batteries can be very expensive, and there are a lot of choices out there! If I have found a reliable power source for my radio at an economical price, then I'll consider that a win. Hooked up to a radio. It maintained voltage well. I set the radio on scan and ran it down to below 50%, which took longer than I expected. Used the correct charger to top it off to 100%. Let it sit for a week disconnected. When I hooked it back up again it was at 76%. ... show more
