NASA BM-1 Battery

The BM-1 is designed to monitor performance of 12 volt lead acid battery systems with capacities of up to 600 Amp hours. It is supplied complete with a precision 100 AMP shunt and a prefabricated cable assembly to enable simple DIY installation. The unit continuously monitors voltage, current (charge or discharge), number of amp/hours (charge or discharge), the batteries state of charge and the time to charge or discharge. It also monitors the voltage of the engine strat battery. This information leads to more efficient use of the battery, which can enhance battery life and reduce the risk of failure. Fully monitors domestic battery/bank Monitors voltage of engine start battery Specifications: - Supply voltage - BM-1 12V 8 – 16 Volts DC - BM-1 24V 16 – 32 Volts DC - Supply current 1.5 milliamps - Battery capacities 5 – 600 AMP Hour - Load current 100 AMPS Maximum - Charge current 100 AMPS Maximum - Shunt Standard 50 millivolt @ 100 AMP Cables supplied: - 100 AMP shunt link to M8 Ring terminal. - 5 Metre from display unit to battery – fused and fitted with ring terminals for shunt, fuse holder and M8 ring terminal to battery. - Display unit - Standard 110mm square Clipper case.
