AMPS - Battery Monitor BM2 The Battery Monitor - 2 (BM2) is AMPS’ high precision power management device, intended for use in the DC negative. Installed correctly, the shunt will accurately measure discharge and charge at any given time.The BM2, as a modern battery solution, is suitable for all battery types (Lead acid, Lithium, etc) and is able to be read both from a live Bluetooth feed as well as from the remote fitted to the unit.The BM2 monitors your battery bank and DC circuits, giving you accurate information on :Remaining battery capacity (measured both as Ampere Hours and as a percentage reading)Battery bank voltage (in Volts)Current passing the shunt at any given time (in Amperes)The App will also provide history and data-logging for your systemThe BM2 comes with :1x Bluetooth compatible remote display1x BM2 shunt (with mounting bracket)1x Shunt power cable (1m)1x Remote cable (1m by default, 3m and 6m options available - if shunt and remote are further away that 1m) IP44 rated Amperage Rating Continuous Up to 500A Maximum current monitoring Up to 999A BM1 Bolt Size 8mm / M8 - 40mm long Working Voltage Range 8V-80V Wattage consumption 0.144W (12mA at 12V) Standby consumption 0.006W (0.5mA at 12V) Quiescent / Sleep current 0.0006W (50uA at 12V) Capacity accuracy +/-0.5% Voltage accuracy +/-0.5% Current accuracy +/-0.5% Capacity Ah setting up to 999Ah | 9999Ah (app) Weight 600.0g (Shunt + Remote) IP rating IP44 rated BM2 - remote | shunt | 1m cable3m - 3 meters of corded extension cable between shunt and remote (optional needs adding to cart)6m - 6 meters of corded extension cable between shunt and remote (optional needs adding to cart) 3m / 6m can be added to the existing 1m. 3m +1m or 6m +1m becomes the maximum length if ordered.
