The Victron Energy Battery Balancer is a battery equalizer that eliminates charge imbalance between series-connected 12V batteries in 24V and 48V banks, drawing up to 1A from the highest battery so all units converge to the same state of charge. It's the best-fit purchase for owners of lead-acid or lithium series banks suffering premature capacity loss. Buy online now for $39.32 — half off the $78.63 compare-at price — and apply coupon OUTPOST12 for an extra 12% discount.
A 48V bank (four series 12V batteries) needs three Battery Balancers — one across each adjacent battery pair. A 24V bank needs just one balancer across the two series batteries. Multiple balancers can be paralleled for higher balance current if needed.
Connect the balancer across the two series 12V batteries: sense leads to each battery's positive terminal and the common midpoint. When charge voltage exceeds 27V in a 24V system, the balancer activates and pulls up to 1A from the higher-voltage battery, equalizing the pair. Installation should follow applicable electrical codes.
Versus passive equalizers or replacing batteries early, the Battery Balancer directly fixes the root cause of imbalance for $39.32. It's the affordable, proven Victron solution compared to costly balancer modules from lesser brands.

Three. One balancer across each pair of adjacent series 12V batteries in the 48V string. A 24V bank needs only one.
Connect it across the two series 12V batteries — sense leads to each positive terminal with the common midpoint. It activates when charge voltage exceeds 27V and balances the pair at up to 1A.
Yes. It works with series-connected 12V lithium banks, helping keep individual batteries at equal state of charge. Verify your lithium BMS configuration supports top balancing across batteries.

My 48V bank had one battery consistently lagging and I was babying it constantly. Two months with the Battery Balancer and all eight batteries now hold equal voltage. Simple to install, silent operation, and it should meaningfully extend bank life. Should have installed this from day one.
Wired it across my 24V series pair per the manual, LED confirmed operation, and I haven't thought about it since. Voltages check equal every time I test. Exactly what it's supposed to do.
One balancer handles a 24V pair but a 48V bank needs multiple units — read the manual before ordering so you buy the right count. The unit itself works well and has kept my series strings matched for a year now.
It does equalize, but don't expect overnight miracles — it took several weeks to bring my drifted bank back into line. Patience required. Build quality is good and it runs cool.
Noticing my older flooded batteries no longer taper off unevenly by the afternoon. Charging completes faster as a whole because no single laggard holds the charger on. Great little device.
If you run 24V or 48V from series 12V batteries, imbalance is silently killing your capacity. This addresses it automatically. Installation is simple if you're comfortable with battery wiring. Only knock is the price for multi-unit setups.
Quiet, cool, effective. Bank voltages are matched for the first time in years.
