12V to 14.6V 10A DC-DC LiFePO4 Battery Charger | Lithium Iron Phosphate Charging 146W

Charge Your LiFePO4 Battery at the Correct Voltage — Directly from Any 12V Source

Upgraded to lithium iron phosphate (LiFePO4) batteries for your RV, boat, or off-grid system? You need a charger that outputs exactly 14.6V — the correct full-charge voltage for LiFePO4 chemistry. The Jason Bang Power 12V to 14.6V 10A DC-DC LiFePO4 Charger delivers precisely regulated 14.6V at 10A (146W) from any 12V or mixed-voltage source, with no AC outlet required.

Unlike generic "smart chargers" with unnecessary charge profiles for LiFePO4 cells, this DC-DC module provides constant-voltage regulated output at 14.6V — exactly what a lithium BMS expects to complete the charge cycle. Simple, reliable, and engineered for permanent installation in dual-battery systems, solar storage, and mobile power setups.

Why 14.6V for LiFePO4?

LiFePO4 batteries have a nominal voltage of 12.8V and a full-charge voltage of 14.2V–14.6V. Charging at 13.8V (lead-acid voltage) will chronically undercharge your lithium battery, reducing usable capacity and shortening cell life. This converter is purpose-built to deliver the correct charge voltage.
