For lead-acid replacement projects, confirm charger settings, current requirements, terminal layout, and installation space before selecting the battery.
Use a compatible LiFePO4 charger with a CC/CV profile. The recommended charging current is 64A, with a charge voltage of 14.4V ± 0.2V.
The battery includes self-heating and low-temperature protection. Follow the product manual for heater activation and charging conditions; low ambient-temperature operation depends on the battery reaching its permitted charging temperature. Heating time varies with starting temperature and installation conditions.
Series and parallel installations require compatible, correctly matched batteries. Confirm the permitted configuration, charger and inverter compatibility, cable sizing, fusing, and terminal polarity with Surlon Power before installation. Share any startup or surge-current requirements as part of the system review.
