24V 230Ah LiFePO4 Battery

Double down on voltage & adventure

Running a 24V leisure electrical system? We’ve used the same cells, case, and BMS as our flagship 460SMART3 battery to create a new 24V 230Ah model. You can now enjoy all the benefits of our 12V SMART batteries - just with a different cell configuration to double the voltage. Each battery provides a colossal 6400W of continuous charging and discharging.
