Customer Reviews

Overall rating: 4.5 / 5 from 2 reviews.

It’s been pretty reliable over the last year. I bought the BMS as well for closed loop control. Easy to install other than weighing 300lbs. I don’t love the cell voltage limits seems like they are under utilizing the battery, probably in the name of safety. Overall good hardware and support though so I recommend
