FAQ
1. What is the expected lifespan and cycle count of this battery?
The Callsun 12V 100Ah LiFePO4 Deep Cycle Battery with 100A BMS offers up to 5,000 cycles at 80% depth of discharge, providing a lifespan of around 10 years under normal usage conditions.
2.How many batteries can I connect together in series or parallel?
The battery supports up to a 4S4P configuration (4 in series and 4 in parallel). This allows you to build an expandable modular 12V to 48V system with a maximum energy capacity of up to 20.48kWh.
3.Can this deep cycle battery be used to start a car or truck engine?
No. This is a deep cycle battery designed for continuous power storage and backup. It cannot provide the massive cranking amps required to start a standard vehicle engine.
4.What size inverter can I safely use with the built-in 100A BMS?
The integrated 100A BMS limits the maximum continuous discharge current to 100A. For a single 12V battery, you should pair it with a maximum 1000W to 1200W inverter to prevent triggering overcurrent protection.
