  • E-bike battery
It’s a great e-bike battery.

  • E-assist fuel
May require a modification of the power cable depending on your configuration. Good value for the price.

  • 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. ... show more

  • Good stuff
The battery has met my expectations in every way.

  • Third Time's the Charm
After receiving 2 batteries that you couldn't remove the key while in use (riding) even though the seller said they had them, they finally sent the upgraded model. With work, it just fit with 1/4" to spare on a 2016 Rad Rover. They said it would fit, and it did. This will require modification of the mounting bracket to fit the Rad's bracket receivers. As well, you'll be crimping or soldering the electrical connection. ... show more

  • It’s working
Still testing, bought the 13ah a few years earlier and that one is already not holding a charge. This one advertises a better cell, we shall see. The 13ah one no longer seems to be available so maybe this one will hold up.

  • The connector on the bottom failed with the first use, the warrantee is only good for 1 month.
DO NOT BUY! The connector on the bottom burned up. The warrantee is only good for 1 month! Most of the projects I do it takes me at least one month before I get around to even unboxing the unit.

  • 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. ... show more
