It does not disconnect the pack on over-charge, over-discharge or over-current. Use a fuse, and a charger and load suited to the pack's limits.\u003c\/p\u003e\u003ch3\u003eCharging and voltage\u003c\/h3\u003e\u003cp\u003eThis pack is designed for 12V vehicle systems. Six 2.3V cells in series give a nominal 13.8V. The charge cut-off voltage of 17.4V (2.9V per cell) is a limit, not a voltage to charge to for use in a vehicle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCharge the pack with a 13.8V charger. A 13.8V source stays well below the 17.4V charge cut-off, so the usable capacity may be lower than the nominal figure.\u003c\/li\u003e\n\u003cli\u003eDirect connection to a vehicle alternator has not been confirmed. The alternator's charging voltage and current must be checked for your vehicle first. To charge from the engine, a current-limited DC-DC charger suited to 6S LTO packs is recommended.\u003c\/li\u003e\n\u003cli\u003eDo not charge the pack to 17.4V with another charger and then connect it to 12V equipment. A fully charged pack is at a higher voltage than many 12V systems accept. Check the maximum voltage of your equipment first.\u003c\/li\u003e\n\u003cli\u003eDo not discharge below 9V. The pack will not stop discharging by itself.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AURINET POWER","offers":[{"title":"30Ah","offer_id":68503334912281,"sku":"AP-L12-30","price":260.0,"currency_code":"USD","in_stock":true},{"title":"40Ah","offer_id":68503334945049,"sku":"AP-L12-40","price":305.0,"currency_code":"USD","in_stock":true},{"title":"45Ah","offer_id":68503334977817,"sku":"AP-L12-45","price":310.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1037\/3385\/4489\/files\/Aa8c7c31ad4cd49e2aa5017ac5a55ca12S.webp?v=1793947961","url":"https:\/\/aurinetpower.com\/products\/ap-l12-12v-lto-battery-pack-car-audio","provider":"AURINET POWER","version":"1.0","type":"link"}
