Well made. Quality product. Great Customer Service
It was perfect for what we needed! AWESOME REPLACEMENT / UPGRADE - it has everything you need. All in one kit. This was a God-send for us. One of our ebike suppliers experienced massive battery failures with no warranty replacements available. This company's product has really come through for us. It has a roomy front compartment for the controller (control module) and all the wires can run through that front panel seamlessly. Well thought out. Well made. Beautiful battery pack and rack. Top notch. Very impressed. No issues. We just ordered four more actually. FIVE STARS

Great Product, Excellent Service!
I purchased the Joyisi R006 36V 14.5 AH battery to use with a 36V 250W Bafang/8 Fun BBSO1B Mid Crank motor kit. My son installed it on my Rans VRex Recumbent, and it is fantastic. I've charged the battery twice using it to run the motor through all 5 levels of help with no problems, and the rack makes for a sturdy and secure platform for the battery.At some point in the first week I lost one of the two keys meant to lock the battery to the rack. I couldn't copy the key locally, so I wrote to Joyisi through Amazon. They quickly contacted me by email, and sent me a new locking mechanism with two keys. Their response was very prompt, and the new lock was easy to install.I would recommend this battery/motor combination to anyone - five stars!
