Equalises the state of charge of two series-connected 12 V batteries (24 V)
Use several to balance 48 V banks or series-parallel strings
Turns on above 27.3 V, so it only works while charging
Draws up to 0.7 A from the higher battery to bring them back into balance
Alarm relay and LED indicators if the deviation gets too big
Alarm reset terminals for a push button
Over-temperature protection
Only 0.7 mA draw when off
Where to use it
The Battery Balancer is for 24 V and 48 V lead-acid battery banks (AGM, gel or flooded) made from 12 V batteries in series, in boats, motorhomes and off-grid systems.
A small imbalance between batteries in series causes one to be overcharged and the other undercharged, shortening the life of the whole bank. The balancer corrects this and alerts you if a battery is failing.
