color:#2D3748;\"\u003e\n Yes. The charger has two independently operating banks: a 12V 15A bank and a 36V 10A bank. The 12V bank can be set to LiFePO4, lead-acid, or AGM mode, while the 36V bank is dedicated to a compatible 36V LiFePO4 battery.

Do not assume that one 36V output will correctly balance three independent 12V batteries connected in series. Follow the individual battery manufacturer's series-charging instructions; use a multi-bank 12V charger when each 12V battery must be charged and balanced separately.\n \u003c\/p\u003e\n \u003c\/details\u003e\n\n \u003cdetails style=\"background:#FFFFFF; border:1px solid #E2E8F0; border-left:5px solid #ED1B4A; border-radius:10px; padding:18px;\"\u003e\n \u003csummary style=\"cursor:pointer; color:#1A202C; font-weight:700; font-size:16px; line-height:1.4;\"\u003e\n Can I permanently mount this charger inside my boat?\n \u003c\/summary\u003e\n \u003cp style=\"margin:14px 0 0 0; color:#2D3748;\"\u003e\n Yes. It is designed as an onboard charger and uses an IP67 epoxy-filled enclosure. Mount it securely with the published 6.5mm mounting holes and appropriate M6 hardware, maintain more than 30mm of clearance, and keep the cooling area unobstructed. IP67 does not excuse damaged cables, loose glands, poor mounting, or unsafe AC connections.\n \u003c\/p\u003e\n \u003c\/details\u003e\n\n \u003cdetails style=\"background:#FFFFFF; border:1px solid #E2E8F0; border-left:5px solid #2E91E5; border-radius:10px; padding:18px;\"\u003e\n \u003csummary style=\"cursor:pointer; color:#1A202C; font-weight:700; font-size:16px; line-height:1.4;\"\u003e\n Is the charger fanless?\n \u003c\/summary\u003e\n \u003cp style=\"margin:14px 0 0 0; color:#2D3748;\"\u003e\n No. The charger uses an aluminum housing and bottom cooling plate together with a temperature-controlled waterproof cooling fan. The fan operates as needed for heat management.
