Adjust the cut-off voltage to 14.6V (4S LiFePO4) or 3.65V per cell. The adjustable thresholds support both Li-ion and LiFePO4 chemistries.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: What is the maximum current this module can handle?\u003c\/strong\u003e\u003cbr\u003eA: The relay contact rating determines maximum current. Check the relay specifications on your specific module — typically 10A to 30A depending on the relay used.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Can I use XH-M603 with a 12V lead-acid battery?\u003c\/strong\u003e\u003cbr\u003eA: The module is designed for lithium batteries. For lead-acid batteries, the voltage thresholds differ (13.8V float, 14.4V absorption) — adjust accordingly, but a dedicated lead-acid charge controller is recommended.\u003c\/p\u003e\u003chr\u003e\u003ch3\u003ePackage Contents\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1× XH-M603 Lithium Battery Charging Control Module\u003c\/li\u003e\u003c\/ul\u003e","brand":"Keszoox","offers":[{"title":"XH-M603","offer_id":46991475310827,"sku":"14:350852#XH-M603","price":12.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1005\/8731\/files\/xh-m603-12-24v-lithium-battery-charging-control-module.webp?v=1761630994","url":"https:\/\/keszoox.com\/products\/xh-m603-lithium-battery-charging-control-module-12-24v-led-display-auto-cutoff","provider":"Keszoox","version":"1.0","type":"link"}
