It is designed for installers building 24V systems from 12V batteries, where small differences in cell condition or charge acceptance cause imbalance over time. Left uncorrected, this imbalance shortens battery life and reduces usable capacity. The Battery Balancer corrects this automatically without any need for programming or user adjustment.\u003c\/p\u003e\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBalances two 12V batteries wired in series in a 24V battery bank, correcting voltage differences between them.\u003c\/li\u003e\n\u003cli\u003eActivates automatically once the difference between the two batteries exceeds 0.1V, drawing up to 0.7A from the higher battery.\u003c\/li\u003e\n\u003cli\u003eRequires no configuration, software or user intervention once wired in.\u003c\/li\u003e\n\u003cli\u003eLED indicator shows balancing activity at a glance, making it easy to confirm correct operation during installation checks.\u003c\/li\u003e\n\u003cli\u003eMultiple Battery Balancers can be connected in series for 48V systems built from 12V batteries.\u003c\/li\u003e\n\u003cli\u003eCompact, sealed enclosure suited to installation in battery boxes, plant rooms and marine or vehicle compartments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eIn a 24V bank made from two series-connected 12V batteries, one battery will often charge or discharge slightly faster than the other due to manufacturing tolerance, age or temperature variation. Over repeated cycles this drift widens, leading to one battery being consistently overcharged while the other is undercharged. The Battery Balancer monitors the midpoint voltage between the two batteries and draws current from the higher one whenever the imbalance exceeds 0.1V, bringing both batteries back into alignment.\u003c\/p\u003e\n\u003cp\u003eBecause the unit works passively and continuously, it requires no interaction with the charge controller, inverter or battery monitor. It sits alongside the battery bank and does its job independently, which makes it straightforward to retrofit into existing 24V systems as well as specify for new installations. For 48V banks built from four 12V batteries, two Battery Balancers are wired in series to cover both halves of the bank.\u003c\/p\u003e\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSKU: BBA000100100\u003c\/li\u003e\n\u003cli\u003eGTIN: 8719076020950\u003c\/li\u003e\n\u003cli\u003eWeight: 0.34 kg\u003c\/li\u003e\n\u003cli\u003eActivation threshold: 0.1V difference between batteries\u003c\/li\u003e\n\u003cli\u003eBalancing current: up to 0.7A\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e24V battery banks assembled from two 12V lead-acid, gel or AGM batteries in series.\u003c\/li\u003e\n\u003cli\u003e48V battery banks assembled from four 12V batteries, using two Battery Balancers.\u003c\/li\u003e\n\u003cli\u003eOff-grid solar installations where consistent charge balance extends battery service life.\u003c\/li\u003e\n\u003cli\u003eMarine and vehicle 24V systems where space for balancing equipment is limited.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Victron Battery Balancer\u003c\/li\u003e\n\u003cli\u003eConnection cables for wiring across the battery pair\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eFit the Battery Balancer across the midpoint of the 24V bank, connecting to the positive and negative terminals of each battery in the series pair. Confirm battery chemistry and wiring configuration before installation. For 48V banks, install two units in series and verify polarity carefully. As with any DC battery wiring work, use a qualified installer where the system forms part of a wider solar PV, inverter or off-grid installation.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":47486537204046,"sku":"BBA000100100","price":35.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/victron-battery-balancer-bba000100100-212552.jpg?v=1747941520","url":"https:\/\/voltaconsolar.com\/products\/victron-battery-balancer-24v-48v","provider":"VoltaconSolar","version":"1.0","type":"link"}
