What is the recommended battery bank for thrusters?

Sleipner recommends that the thrusters are connected to a battery bank that is not protected by a Battery Management System (BMS).

Typically this means lead-acid, AGM, gel, or similar kinds of batteries. This is important because thrusters draw a lot of currents quickly, and the high amp draw may lead the BMS system to think that there is an issue with the system and consequently disconnect the batteries from the circuit, in which case you would lose maneuverability.

Disclaimer: Ensure battery/energy source is installed according to CE/ISO current rules and regulations and by licensed electricians.
