Availability: In Stock
Marsen Energy 36V 17.5Ah Carbon GT Electric Skateboard Battery Upgrade. It uses Panasonic 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 Evolve standard or fast charger. The cells are spot welded together with 99.9% pure 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) BMS not supplied, the BMS from existing Evolve battery is required. The 12AWG silicone power leads are fitted with T-style Deans connector and a high current clamp connector for a solder free fast connection. We recommend the use of a heatsink spacer to provide extra space to fit the larger battery as well as extra space for cooling. These are available from us. Spacer

# Power capacity according to the specifications of the cell manufacturer. The power capacity available during operation is lower to increase service life.
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
