Victron Battery Balancer

Battery balancer for series-connected 12V batteries in 24V and 48V battery banks. It equalises state of charge between battery legs to reduce imbalance during charging.

Key Features
State-of-charge balancing

Balances two series-connected 12V batteries, or multiple parallel strings of series-connected batteries, to help equalise charge levels.

24V and 48V system use

Suitable for 24V battery systems and 48V battery banks; multiple balancers can be used in larger banks.

Voltage deviation monitoring

Starts balancing when midpoint deviation exceeds 50 mV, with LED indication at higher deviation levels and alarm at 200 mV.

Alarm relay output

Includes a normally open 60V / 1A alarm relay for external signalling when the alarm condition is reached.

Protection and operating range

Features over-temperature protection, IP22 enclosure and an operating temperature range of -30 to +50°C.

Benefits
  • Helps reduce imbalance-related undercharge, overcharge, gassing and sulphation.
  • Supports batteries converging to the same state of charge during charging.
  • Can be used in larger battery banks by paralleling multiple balancers where required.
  • Provides a relay output for external alarm signalling.
Technical Summary

Victron Battery Balancer for up to 18V per battery and 36V total. Turn-on level 27.3V +/-1% and turn-off level 26.6V +/-1%. Maximum balancing current 0.7A when deviation exceeds 100 mV. Alarm trigger level 200 mV and reset level 140 mV. Normally open alarm relay rated 60V / 1A. Screw terminals 6 mm² / AWG10. IP22 enclosure, 0.4 kg, dimensions 100 x 113 x 47 mm.

Installation Notes

Install on a well-ventilated vertical surface close to the batteries, but not above them due to possible corrosive gases. Use at least 0.75 mm² for negative, positive and midpoint connections. In series-parallel connections, midpoint interconnecting cables must be sized to carry the current that can occur if one battery becomes open-circuited. If required for UL compliance, fuse these wires near the batteries with a 10A DC fuse.

Efficiency

Helps address state-of-charge imbalance that can shorten battery service life. Better and regular charging may resolve systematic undercharge issues in older battery banks.
