AMPS - Battery Monitor BM1
The Battery Monitor - 1 (BM1) 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 BM1, 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 BM1 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, of course)
Current passing the shunt at any given time (in Amperes)
The App will also provide history and data-logging for your system
The BM1 comes with :
1x Bluetooth compatible remote display
1x BM1 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). Additonal 3m / 6m shall give you 4m or 7m respectively as you use the pre-existing 1m as well.
