Marsen Energy 36V 15Ah Carbon GT Electric Skateboard Battery

The 15Ah battery upgrade uses the new generation Samsung INR1865030Q-T6 3000mAh cells in a 10S5P configuration to provide up to 100 amps continuous. The nominal voltage is 36V with a charge voltage of 42 volts so it can be charged using Evolves 2A charger or the fast 4A charger. Marsen Energy also sell the 4A fast chargers suitable for this battery. 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 compared to standard silicone AWG wire. It has an 11 wire JST connector for BMS balancing (compatible with Evolve BMS). BMS not supplied, BMS from existing Evolve battery required. The 12AWG silicone power leads are fitted with T-style Deans connector and a high current clamp connector, no soldering required. 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 (recommended). Spacer

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
