Marsen Energy 36V 17500mAh Carbon GT Electric Skateboard Battery Upgrade

Marsen Energy 36V 17500mAh Carbon GT Electric Skateboard Battery Upgrade. It uses Sanyo GA 3500mAh cells in a 10S5P configuration to provide up to 50 amps continuous or 80 amps for short periods ( 2-3 mins) . The nominal voltage is 36V with a charge voltage of 42 volts so it can be charged using our standard 2A charger or the fast 4A charger. The cells are spot welded together with Nickel strips using a commercial grade 15KVA inverter battery welder for strong quality welds. The 5P sections are joined with braided copper wire to increase flexibility of the pack as well as reducing the width of the pack. It has an 11 wire JST connector for BMS balancing (compatible with Evolve BMS) The 12AWG silicone power leads are fitted with T-style Deans connector and a high current clamp connector for a solder free fast connection so batteries can be changed in the field. We can supply a custom designed plastic spacer for the controller heatsink to provide extra space to fit the larger battery as well as extra space for cooling.

The shipping price on these batteries includes full insurance to cover for the unlikely event of damage or loss during freight. 

Voltage Sag

One of the main issues with the some electric skateboard batteries is voltage sag when under high load such as going up hills. By using a higher rated cell the voltage sag can be reduced.  For a more detailed explanation of voltage sag see Jay Boston's youtube clip. Voltage Sag
