Marsen Energy 36V 12Ah High Power BGT/BGTX Skateboard Battery

This is the high power version of the battery upgrade for Evolve Bamboo One, Gen 2, GT and GTX. It uses Samsung INR21700 40T 4Ah cells and can output 50% more power than the standard 12Ah. 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 99.99% pure Nickel strips using a commercial grade 15KVA inverter battery welder for strong quality welds. 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.

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 designed to make installing the battery easier 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 INR21700 40T cell is rated to 30 Amps so voltage sag is reduced to a minimum when a 10S3P battery pack is used. This will provide 90 Amps continuously and over 120 Amps for short periods. For a more detailed explanation of voltage sag see Jay Boston's youtube clip. Voltage Sag
