Marsen Energy 36V 12Ah GT Electric Skateboard Battery Upgrade for Evolve Bamboo One, Gen 2, GT and GTX. It uses the new generation Samsung INR1865030QT-6 3000mAh cells with a higher output of 20A. 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 4P 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. It has upgraded 12AWG silicone power leads (compared to the standard 14AWG) and fitted with T-style Deans connector and a high current clamp connector for a solder free connection.

Watch the installation guide to see how to upgrade.

Please allow up to 10 days lead time as batteries are made weekly from fresh cells to ensure the highest quality product. Our batteries are not stored for weeks at a time. Special requests for different configurations or plug types can easily be arranged.

The shipping price on these batteries includes insurance. 

All Evolve Bamboo boards require modifications to fit these larger upgrade batteries. Marsen Energy offer a riser plate for installing the battery providing the required extra space to house the larger battery. These are available for $55, they are CNC machined from ABS plastic and come with longer screws. 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. The Samsung INR1865030Q cell is rated to 20 Amps so voltage sag is reduced to a minimum when a 10S4P battery pack is used. This will provide safely 80 Amps continuously and over 100 Amps for short periods. For a more detailed explanation of voltage sag see Jay Boston's youtube clip. Voltage Sag
