The Victron Battery Balancer draws a limited current from the higher-voltage battery so a properly matched 24V lead-acid bank can charge more evenly.\u003c\/p\u003e\n\u003c\/div\u003e\u003csection style=\"margin:26px 0;padding:28px;color:#0B1220;line-height:1.7;\"\u003e\u003ch3\u003eChoose the number of balancers for the bank\u003c\/h3\u003e\n\u003cp\u003eOne balancer is designed around two 12V batteries in series, forming a 24V bank. A 48V string made from four 12V batteries requires three balancers in the manufacturer’s arrangement. This listing includes one unit, not the three-unit set needed for that 48V configuration. Review the diagram for parallel strings as well as series connections.\u003c\/p\u003e\n\u003ch3\u003eUnderstand the limited balancing current\u003c\/h3\u003e\n\u003cp\u003eBalancing begins when the voltage difference reaches about 50mV. The unit draws up to 0.7A from the higher-voltage battery when the difference exceeds 100mV. It is intended to help manage battery-to-battery imbalance during charging, rather than to supply the charging current for the whole battery bank.\u003c\/p\u003e\n\u003ch3\u003eCheck charging thresholds and voltage limits\u003c\/h3\u003e\n\u003cp\u003eThe balancer turns on at approximately 27.3V, with a specified tolerance of ±1%, and turns off around 26.6V. Its maximum is 18V per battery and 36V total across each balancer. Confirm the charging profile and battery arrangement against those limits; nominal voltage alone does not describe every operating condition.\u003c\/p\u003e\n\u003ch3\u003eUse indicators and the alarm contact\u003c\/h3\u003e\n\u003cp\u003eA green LED indicates operation, orange indicators identify the balancing side and a red LED indicates an alarm. The alarm threshold is a 200mV difference and resets around 140mV. A normally open alarm relay is rated 60V\/1A. An external reset button can be added separately according to the wiring instructions.\u003c\/p\u003e\n\u003ch3\u003eInstall close to the bank in a protected location\u003c\/h3\u003e\n\u003cp\u003eThe unit measures 100 × 113 × 47mm in height, width and depth and weighs about 0.4kg. It is rated IP22 with an operating range of -30°C to +50°C. Mount vertically in a ventilated location close to the batteries, but not directly above them where corrosive gases can collect. Screw terminals accept up to 6mm², approximately 10 AWG; select the actual wiring and protection from the manual.\u003c\/p\u003e\n\u003ch3\u003eStart with suitable, fully charged batteries\u003c\/h3\u003e\n\u003cp\u003eBalancing equipment cannot repair a defective battery or correct every consequence of mismatched age, capacity or condition. Follow the manufacturer guidance for initial charging and battery matching before putting the bank into use. Persistent imbalance deserves investigation rather than simply adding more balancing devices.\u003c\/p\u003e\n\u003ch3\u003eWhat is included?\u003c\/h3\u003e\n\u003cp\u003eOne Victron Battery Balancer, exact SKU BBA000100100. Batteries, battery charger, cables, fuses and optional alarm-reset button are separate. For a four-battery 48V series string, select the required quantity of three individual units and follow the official connection diagram.\u003c\/p\u003e\n\u003ch3\u003eIs this an internal lithium cell balancer?\u003c\/h3\u003e\n\u003cp\u003eNo. This product works between the specified series-connected batteries. It does not replace an internal cell-level BMS or make an arbitrary lithium arrangement compatible. The manufacturer’s lead-acid series-bank application and voltage limits should guide selection; confirm any other application directly before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"\/collections\/accessories\"\u003eCompare power accessories\u003c\/a\u003e · \u003ca href=\"\/pages\/power-planner\"\u003ePlan your battery system\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.victronenergy.com\/upload\/documents\/Manual-Battery-Balancer-EN.pdf\"\u003eManufacturer specifications and installation guidance\u003c\/a\u003e · \u003ca href=\"\/pages\/contact\"\u003eAsk Torven Power about compatibility\u003c\/a\u003e\u003c\/p\u003e\u003c\/section\u003e\u003c!-- TORVEN_DESCRIPTION_END --\u003e\u003c!-- TORVEN_SPECIFICATIONS_START --\u003e\u003csection style=\"margin:26px 0;padding:28px;border:1px solid #E5E7EB;border-radius:14px;background:#FFFFFF;\"\u003e\u003cp style=\"margin:0 0 8px;color:#DEA61D;font-size:13px;font-weight:800;letter-spacing:1.2px;text-transform:uppercase;\"\u003eProduct Data\u003c\/p\u003e\n\u003ch2 style=\"margin:0 0 14px;color:#0B1220;font-size:26px;line-height:1.25;\"\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x:auto;border:1px solid #E5E7EB;border-radius:12px;\"\u003e\u003ctable style=\"width:100%;border-collapse:collapse;font-size:15px;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background:#0B1220;color:#FFFFFF;\"\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eManufacturer\u003c\/th\u003e\n\u003ctd style=\"padding:14px 16px;\"\u003eVictron Energy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eExact SKU\u003c\/th\u003e\n\u003ctd style=\"padding:14px 16px;\"\u003eBBA000100100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eTypical arrangement\u003c\/th\u003e\n\u003ctd style=\"padding:14px 16px;\"\u003eTwo 12V batteries in series;
