Customer Reviews
After 3 months of waiting, my battery finally arrived. Chilean customs delayed the delivery process, but the seller quickly shipped the battery. I thank the seller and the team for extending the cable that connects to the motor because I have an Imortor 3 and will be able to leave the battery in a bicycle luggage rack. I had no problem starting the motor; I just need to assemble it and test its effectiveness on the road. The Imortor 3 batteries have very low capacity. Thank you, I will update my review on the road.
Ordered one each of 40A and 20A... It was frustrating because the delivery status wasn't updated, but it finally arrived... The 40A connection jack was unexpected and slightly misaligned, but it shouldn't cause major issues during installation.
40A is very heavy. Adult male: It feels heavy in one hand, about 15 kg. This will be used for Bafang Motor.
20A is going to be used as a supplement for my existing short-legged bicycle this winter and then disposed of... The low winter temperatures are tough on electric batteries... I'm considering using the Styrofoam packaging as insulation material.
Got my order fast packaging was good the seller checked in a week later to ask about battery use i’ll tell my friends to buy here
Tried so many e-bike batteries before but this one’s a total game-changer! The seller even checked in after delivery to make sure i got it working—such a nice touch
As someone who commutes 15 miles daily this battery is a lifesaver i charge it once a week and the seller walked me through every setup step when i got stuck
