Frequently Asked Questions
The system features high-performance lithium iron phosphate (LiFePO4) batteries with laser welding technology, designed for a lifespan exceeding 10 years under stable charging and discharging conditions.
The system has an IP20 protection rating, meaning it is designed primarily for indoor or sheltered environments. It is ideal for outdoor adventures or temporary power supply when housed in proper protective enclosures or dry conditions.
It features multiple protective functions, including input reverse polarity, under-voltage, over-voltage, output over-current, short circuit, and overheating protections, combined with active fan cooling.
The master-slave architecture works alongside passive balancing technology to monitor voltage differentials and manage balancing resistors. This prevents the "bottleneck effect" across battery modules, maximizing overall capacity and safety.
Yes, the system enables independent charge and discharge control. Even during overcharging or over-discharging states, the system maintains continuous connections at the ports to ensure an uninterrupted energy supply.
