    Great battery.
  

*by K***0 on Reviewed in the United States on October 18, 2019*

I installed this on a fat ebike build and I weigh 280lbs. This battery will allow me to travel at least 20 miles on a single charge. The straps are great, and are tough. The straps also work great to protect the frame as pictured.
