The 24V 25Ah LiFePO4 Battery is a 25.6-volt pack of 640 watt-hours on M6 terminals, rated IP65. It is the entry size in the 24-volt range, for small trolling motors, solar lighting columns and light industrial equipment.
Why 24 Volts
Half the current for the same power
Power is volts times amps. A 600-watt load pulls 50 amps at 12 volts and 25 at 24. Halving the current halves the voltage drop along a cable run and cuts the heat in every connection, and it lets an installer use thinner, cheaper wire for the same job. A machine built at 24 volts carries that advantage through its whole harness.
The Loads
640 watt-hours in service
A small 24-volt trolling motor, a solar area light on a tall column, a mobile signal board and a light industrial trolley all sit in this band. The 25-amp continuous rating covers those loads, and the 50-amp peak takes a motor start. On a solar column the pack banks a day of panel output for a full night of LED lighting.
Build
Series and parallel
Eight cells in series make the 25.6 volts. Two packs in series reach 48 volts for a larger machine, and packs join in parallel for more capacity once they rest at the same voltage. The M6 terminals take the ring lugs a 25-amp circuit uses.
Solar Sizing
Matching the panel to the night
A solar column pairs the pack with a panel matched to its nightly burn. A 20-watt LED head running twelve hours uses 240 watt-hours, and a 100 to 150-watt panel replaces that across a day of decent sun. 640 watt-hours then leave two full nights in reserve for bad weather. Set the controller to a 24-volt LFP profile and switch off any equalization stage.
