Marsen 14Ah Electric skateboard pack.

• Capacity: 14Ah/14000mAh
• Nominal Voltage: 36V
• Discharge current: 150 Amps
• Standard Charge: 2 Amps
• Fast Charge: 4 Amps
• Charge Voltage: 42V
• Weight: 2500g
• Dimensions: 465mm x 140mm x 19mm

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

The 14Ah battery upgrade uses the newer Molicel P28A high power cells in a 10S5P configuration to provide up to 150 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. It has an 11 wire JST connector for BMS balancing (compatible with Evolve BMS). BMS not supplied, BMS from existing Evolve battery 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

Special requests for different configurations or plug types can easily be arranged to suit custom builds or other brands of skateboards. We can also install a choice of BMS’s to meet your requirements.

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

• Never completely discharge Li-ion battery.
• Charge fully before first use.
• Never use force to install (insert) Li-ion battery.
• Use only a high quality battery charger.
• Do not expose to heat.
• Do not short (connect) positive, and negative battery terminals. Keep battery that is not in use in plastic holder (or any insulating container).
• Do not charge unattended unless using an intelligent charger that shuts off at full charge.
• Do not store your Li-ion batteries fully charged (for extended period of time).
• Store in cold and dry place.
