    • A DIY battery upgrade
I got fittings that worked with the e-bike I had and now I have a new bike but that battery works and came in the mail I keep it in a bag on the handlebars on that bike but it can be mounted and definitely extended my range works well but you have to be careful with it you don't want to touch any of the cables to each other obviously it's just more of a battery for somebody who's okay with it but I do suggest a bag or something to keep it from getting punctured and out exposed I did have it in the rain which I don't even do on my own bike now ... show more

    • This company makes an outstanding product. It has surpassed my expectations!
I have a 1000w 26" bike kit, weigh 260 lbs and it took me 20 miles on a charge. Amazing! Need another one!

    • Own two of these and am happy with both.
I have purchase two of these so far, a 10AH version and a 20AH version. I’m happy to say that they both perform well and seem to be a good value for this kind of product. For reference, I am using a 1000watt 48v ebike kit (voilamart), and weight around 240lbs. With the 10AH version, using a level 2 pedal assist on average, I get around 35-40 miles to the charge. On the 20AH version I get upwards of 80+ miles to the charge. What I LOVE about the 10AH version especially is that it is much more compact than other units out there which makes for a better commuting experience around town in my opinion. ... show more

    • Battery cells leaked
Review Image by Darlene Darlene
I bought this battery in January 2023 and installed it on my son's razor 650. After a month and a half it wouldn't charge. I took the battery out and it immediately felt liquid from inside the battery. I removed the plastic casing the battery itself is only protected by string tape opened it up and everything got eaten away terminals and all. I am trying to get my money back so I can get a replacement. It has been over 6 days and the seller is very reluctant to refunds or replace my battery. ... show more

    • The real deal
The picture shows Panasonic 3400mAh cells and, after receiving two of these, they seem to perform well. I haven't capacity tested them but they certainly aren't those counterfeit fakes you sometime see at unreasonable sizes and prices. Good price, good product, though the barrel charging receptacles are a bit finicky. EDIT: Now that I have capacity tested them, they are closer to 14,000mAh, not 20,000. Still decent for the price but I'm not that thrilled with the false advertising. Further, I've repeatedly contacted the seller about this, with no response. ... show more

    • Good Battery
Seems like a good battery. I've cycled it a few times now and it's holding capacity just fine and can go over 20 miles easily with cpacity to spare.

    • Failed to follow through on return of defective item.
Failed to follow through on return of defective item. They keep promising to take this back but will not provide a return label to allow me to ship back this underperforming battery. This battery only provided about 2/3 the advertised 20 amp hour rating.
