Deep Cycle LiFePO4 Batteries

Start by deciding whether the project actually needs an added function. Compare the Regular series for straightforward power supply, Smart LCD when status must be visible at the battery, Bluetooth for phone-based monitoring, and Self-heating only when low-temperature charging is a defined requirement. Confirm that the required function exists at the selected voltage and capacity.

Start with the energy your equipment uses and the runtime you need. Nominal energy in Wh = battery voltage in V × capacity in Ah. Allow for the usable discharge range, conversion losses and a suitable reserve, then check continuous and peak current as well as capacity.

It is compatible only when its output behavior meets the selected battery’s requirements. Record maximum output voltage, current, charging stages, float, equalization and temperature compensation. Equalization, desulfation or prolonged high-voltage float modes require particular attention and may need to be disabled or replaced.

Only when the exact model explicitly supports the intended configuration. Use batteries of the same model, capacity, batch and state of charge, follow the permitted series/parallel count, use balanced cable lengths and suitable fusing, and do not mix feature series or new and aged batteries.

Self-heating mainly addresses charging conditions in cold environments; it does not remove all low-temperature limits. Provide minimum ambient temperature, cold-soak duration, charging source and available charging power, then check heating start and stop temperatures, heating energy consumption and the battery’s cold charge/discharge limits.
