Power
The nine Paralell cell configuration is capable of 550 amps and BMS restricted to 450Amps. 32.5kW power is easily achievable until BMS roll bakc kisks in. We have spent sevral months testinga nd evaulting the cell we are using and so confident we are extending our cell warranty to 18 months for this battery.
Exoskeleton / Casing
We have upgraded the casing to marine grade 316 stainless steel, so absolutely no rust issues here! Super tough and powder coated inside and out.
Connectors
The main battery to controller connectors we use are QS8 connectors of thicker 6AWG cables. The battery to bile to controler loom is included.
Fitting
The battery fits straight into the OEM bike frame. No need for spacers or hinges. But being 72v will need to fit our after market power loom to the controller via the trip switch fitting. Its a simple job, just swapping out the main red and black power cable.We include this free of charge.
