230Ah
230A Continuous Charge and Discharge with 460A Pulse Capability
The impressive 230A continuous output can easily power a 2000W inverter and handle additional power-hungry 12V devices. With a 460A pulse capability for 30 seconds, this battery can also support a 3000W inverter and compatible devices that surge to 3000W during startup.
4000+ Cycles
4000+ Cycles @ 80% DoD 0.5C
The battery is rated to be discharged at a constant rate of 115A, down to 80% of the battery's capacity, and then recharged at 115A for over 4000 cycles. After this, the battery is rated to have reduced its usable capacity to 80% of the expected capacity.
