These worked well with my refurbished ebikes
I used this replacement battery on my storm damaged ebike and so far (bought two for two bike repairs) it works great. It was more powerful than the original and seems to hold a charge for many days of riding around our winter vacation island. Only time will tell if this replacement e-bike battery will last a number of years. I do hope so, as these are not that cheap and so the cost can be justified IF I can get at least 3 years. These were also much cheaper than the factory originals.

It works and the bike is faster
Appears to be a good battery and I'm happy with the speed increase. I find not having a key ignition on the battery is a negative. It only has a on/off switch which isn't effective anti-theft. This could be an improvement for future iterations. It is a 200$ cheaper battery when compared to the bike manufacturer and is spec wise a better battery. Hopefully it lasts

Very nice
Durable and long lasting battery life. I’ve put over 2800 miles on my bike/battery and it’s held up to drops, mud, rain, and more. They’re not cheap but don’t cheap out on your battery, you’ll only disappoint yourself. I ordered the 20ah size and it has a huge battery life.

Perfect for my eBike !
Used this product for an eBike I built last year. Works VERY well. LONG battery life. Utilize a durable form fitting bag that Velcro's to the bike frame instead of mounting directly to the frame unprotected. Have never drained the unit in a single bike ride. So far, 20+ miles & still have power. Only downside is the weight.

Battery life
Doesnt feel like I got a 20ah battery.. more like a 14ah with a 20ah sticker on it. Gunna take it to get checked.. does not have easy access to fuses and can short out without an easy fix..

Great battery and great service after sale
I liked the battery power overall. I had it installed on a trike and never left me stranded . Plenty of power for hills I also liked support a year plus after the sale I had misplaced my battery lock key and they were willing to provide a replacement key if needed. Luckily I found the key but their willingness to provide support exceeded my expectations!
