The battery balancer equalizes the state of charge of two series connected 12V batteries, or of several parallel strings of series connected batteries. When the charge voltage of a 24V battery system increases to more than 27V, the battery balancer will turn on and compare the voltage over the two series connected batteries. The battery Balancer will draw a current of up to 1A from the battery (or parallel connected batteries) with the higher voltage. The resulting charge current differential will ensure that all batteries will converge to the same state of charge.
If needed, several balancers can be paralleled. A 48V battery bank can be balanced with three Battery balancers.
The Victron Blue Power battery charger is a standalone charger which is directly connected to the national grid used to recharge deep cycle batteries when drained. The Blue power charger regularly checks the state of charge, voltage and reconditions the battery when in an unfavourable condition. The Victron Battery chargers include blue power IP 20/ IP 65
Adaptive four (4)-stage charge characteristic
The Blue Power charger goes through four charge stages to effectively and efficiently recharge batteries: Bulk, Absorption, Float and Storage.
- The bulk charging stage is the charge cycle where the battery is fully drained
- The absorption stage is next after recharging the battery to estimated 70%
- The float charge stage is activated when the battery is fully charged
- The storage charge stage occurs after a couple of hours from the float stage where charge voltage is minimized to the lowest.
