The Victron Energy Battery Balancer (BBA000100100) is designed for users with 24V lead-acid battery banks to equalize the state of charge between series-connected 12V batteries. Its key benefit is improving battery bank longevity and reliability by preventing imbalances. A key caveat is that it is only suitable for lead-acid batteries and operates when charge voltage exceeds 27V. This device automatically diverts up to 1A from the higher-voltage battery to achieve charge balance, requiring no user settings or external control.

It is designed specifically for lead-acid batteries (flooded, AGM, Gel) used in series to create a 24V bank.
This specific model is for 24V systems. For 48V systems, you can parallel three Battery Balancers.
The balancer activates when the charge voltage exceeds 27V. You can monitor the voltage across each 12V battery; the balancer will draw current from the one with the higher voltage, causing their voltages to converge.
The Battery Balancer can divert a maximum of 1 Ampere (1A) from the higher-voltage battery to the lower-voltage battery.
No, the Battery Balancer operates automatically without any user settings or external control required.
In a series bank, an unbalanced battery can lead to undercharging of one battery and overcharging of another during charge/discharge cycles. Over time, this causes premature capacity loss, sulfation, and reduced lifespan for the entire bank.
Yes, multiple balancers can be paralleled. For example, three balancers are needed to balance a 48V battery bank.
Verify that the system voltage is consistently exceeding 27V during charging. Check all wiring connections to ensure they are secure and correct.
Ensure the voltage difference between the two series batteries is significant enough for the balancer to engage (typically more than a few tenths of a volt). Check that the batteries are indeed lead-acid types.
Ensure there is adequate ventilation around the balancer. Check that the battery bank is not severely unbalanced, causing the balancer to divert its maximum current continuously.
The balancer only operates during charging when voltage exceeds 27V. If the system voltage does not reach this threshold, the balancer will not function. Address the charging system itself.
Setup: The Battery Balancer connects directly across the two series-connected 12V batteries in a 24V bank. Ensure the system is disconnected from any loads and chargers before wiring. Follow the wiring diagram provided in the user manual carefully, paying close attention to polarity and ensuring secure connections. The device activates automatically when the charging voltage exceeds 27V.
Compatibility: This product is exclusively designed for lead-acid batteries (flooded, AGM, Gel) configured in series to form a 24V bank. It is not compatible with 12V or 36V systems directly, nor is it suitable for lithium-ion chemistries. For 48V systems, multiple units (three) can be paralleled.
Care: The Victron Battery Balancer is a maintenance-free device. Keep the unit clean and dry. Ensure ventilation around the device to prevent overheating. No user-serviceable parts are inside; refer servicing to qualified personnel.
