36v 40ah battery

1 have a 12ft hunting kayak with the three ho Newport outboard connected to this 40ah 36v lithium battery. The battery management (bms) app is great ! Took this rig out and ran at mostly full throttle for twenty minutes around the lake . When done the battery was still at 91% charge !! All works great!!!!

Dependable smart power!

A quality battery made from quality cells, and from a quality name brand. The Bluetooth connected battery tells me in real-time my usage and remaining range. No reason to have battery/range anxiety with the Newport Vessels battery App. More enjoyable time on the water with less worry!
