## Questions & Answers

**Q: will these fit a ew-m34 scooter?**
A: Thank you for your question, we have checked the parameters of EW-m34 scooter, our battery can be suitable, because it is two batteries in series, we suggest you use 24V lifepo4 charger to charge the battery.

**Q: bms --does it have auto recovery for over discharge on up hill travel ?**
A: Thanks for asking, it has nothing to do with the BMS, the current will increase on uphill and the displayed mileage will decrease, it will slowly return to normal when you get to a flat road.

**Q: Will these batteries work in a golden buzzaround xl gb117?**
A: I have checked the GB117 and our batteries will work, but you will need to check how many amps the original battery is to choose the right one.
Hope my answer helps!

**Q: Will this work for the Tzora Elite mobility scooter?**
A: Yes, it can be applied.

### ⭐⭐⭐⭐⭐ UPDATE 6/3/25 *******Holy crap!!!!!!!! 10 stars still isn't  isn't enough  ****See Note****
*by R***K on October 28, 2024*

** Final Update** Maybe...The last couple days have been intense, and even though I beat the absolute snot out of these batteries, they never missed a beat. Yesterday saw 8 miles around the neighborhood, and only one lost bar. **remember though, it isn't completely accurate** Rescued some ducklings, went to the store a few times, etc...Today however, I hooked up my old bike trailer to the chair and went full grocery shopping. Now even though this was 10 miles round trip, I'm hauling a trailer with a few steep grades along the way. Got to the store, I'd lost a bar, I expected it, so I plugged it in while I shopped using the handy "mart cart" Full load minus trailer was close to 80 pounds (36Kg) With the trailer, and me on board, it was about 260 lbs (118Kg) The full capacity of the chair with 18AH batteries is 300 lbs (140Kg) Remember, these are 12AH. That short 1 hour charge got me all the way to the gas station near my house, where I had to stop anyway. I put it on charge for 5 minutes, and hobbled in to get what I needed and made it home no issues. NEVER, even with my old chair, that had 35AH batteries compares to these. I'm not saying they'll last longer, but they are significantly lighter, and apparently far more power dense. I want to see what a 100AH ones on my trailer will do. Add a solar panel, Unlimited range...lol. Oh, Yeah, that's a cooler on the back, too.7 months in... My old batteries would need replacing by now. These just took me on a 5 mile round trip over on a rough shoulder with a steep hill. Even though these are lower capacity compared to the old lead acid, they more than make up for it in weight savings. Essentially making it easier for the batteries to move the chair.I have a set of smaller ones in my cart for a RC lawnmower project I'm working on. Compared to the old batteries, I wish I could give these 10 stars.**original Review**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.

### ⭐⭐⭐⭐⭐ Great upgrade over SLA batteries
*by J***S on April 2, 2025*

I purchased this battery to replace the worn-out SLA battery in the small UPS (uninterruptable power supply) I use to back up my desktop PC. The decision to switch from SLA to Lithium-iron-phosphate battery chemistry was easy as LiFePO4 batteries cost about the same as SLA batteries but are much lighter and last much longer than SLA batteries. My UPS is over ten years old and, at the time I purchased it, SLA batteries were considered the battery of choice. If purchased today, it’s highly likely the battery would be LiFePO4 technology. LiFePO4 batteries are easily confused with Li-ion batteries commonly used with portable power tools. LiFePO4 batteries are more reliable, have longer lifespans, and are safer than Li-ion batteries. The battery easily fits into the same space as the SLA battery it replaced. I haven’t needed to find out if the battery works as well in a power out scenario, however, my UPS runs a test program several times a week so I’m certain I can rely on it should the need arise.

### ⭐⭐⭐⭐⭐ Update: Li-ion batteries work great. Been 7 months....
*by A***O on March 2, 2023*

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!
