Description
Victron Battery Balancer for 24V/48V Systems | Boat Supply Store
For vessels operating 24V or 48V systems, this device actively equalizes charge state across series-connected 12V batteries, a critical function to prevent premature failure. It activates when system voltage exceeds 27V, drawing up to 1A from the higher-voltage battery to ensure all cells converge to an equal charge level. This technology is particularly beneficial for offshore fishing trips on the Gulf Coast where consistent power is essential and battery bank longevity is paramount.
Key Features
- Equalizes state of charge for two series-connected 12V batteries.
- Balances parallel strings of series-connected batteries.
- Activates automatically when a 24V system charge voltage exceeds 27V.
- Transfers up to 1A of current from the highest voltage battery.
- Ensures all batteries achieve a uniform state of charge.
- Scalable for 48V systems by paralleling multiple units.
- Prevents premature battery failure and extends lifespan.
- Maximizes overall battery bank performance and reliability.

Common Concerns Answered
Will this unit balance individual batteries in a bank, or is it only for series configurations?
The Victron Battery Balancer is specifically designed to equalize the charge state between two series-connected 12V batteries. It is not intended for balancing individual batteries within a bank or for systems that are not configured in series.
Does the battery balancer actively charge the batteries?
No, this unit does not actively charge batteries. Its function is to equalize the existing charge levels between series-connected 12V batteries, ensuring they maintain a similar state of charge and preventing one from being overcharged or undercharged relative to the other.
Is the Victron Battery Balancer compatible with 36V battery systems?
The Victron Battery Balancer is designed for 24V systems (two series 12V batteries) and can be paralleled for 48V systems. It is not compatible with 36V battery banks.
Frequently Asked Questions
What is a Victron Battery Balancer used for?
A Victron Battery Balancer is used to equalize the charge state between two series-connected 12V batteries, ensuring they remain at the same level of charge. This process prevents premature battery failure and maximizes the lifespan and performance of 24V and 48V battery systems.
How does the Victron Battery Balancer work?
When the charge voltage in a 24V system exceeds 27V, the balancer activates and draws up to 1A of current from the battery with the higher voltage, transferring it to the battery with the lower voltage until they reach an equal state of charge.
Can I use multiple Victron Battery Balancers together?
Yes, multiple Victron Battery Balancers can be paralleled to manage larger battery banks, such as 48V systems, by using two units for a 48V bank.
What is the maximum current the Victron Battery Balancer draws?
The Victron Battery Balancer draws a maximum of 1A from the battery with the highest voltage when it is actively balancing the charge.
What voltage triggers the Victron Battery Balancer to activate?
The Victron Battery Balancer activates when the charge voltage of a 24V system exceeds 27V.
