A 12V 40Ah sodium-ion starting battery for engine cranking and start-stop duty, replacing lead-acid in a smaller, lighter envelope. It carries 480 Wh of usable energy and delivers 120A continuous \u2014 a full 3C draw, with headroom for the surge loads motive duty demands.<\/p>\n
Charging at 40A brings it to full in roughly 1.5 hours. The operating window is -40~80\u00b0C on discharge and -20~50\u00b0C on charge. The pack measures 355 x 176 x 188 mm (Group Size H8) and weighs 7.2 kg.<\/p>\n
Within our 12V range this sits between the 30Ah and 42Ah builds. If your runtime target is tighter than expected once we model the duty cycle, the 42Ah configuration is the usual next step; if weight or envelope is the binding constraint, the 30Ah build is lighter.<\/p>\n
Case format, terminal position and polarity, cranking rating and cold-weather behaviour are specified per platform. BMS communication over CAN or RS485 is available where the vehicle expects it, with Bluetooth for diagnostics.<\/p>\n
