• In series, to obtain a 24V system with a capacity of 160Ah
• Separately, to power two independent installations

This flexibility allows for storage adaptation to different projects: camper, converted van, boat, cabin, off-grid hut, or backup power supply.

Two LiFePO4 batteries to replace a heavy and bulky lead set

LiFePO4 technology allows for storing more energy in a lighter and more compact format than an equivalent set of lead-acid batteries. This set of 2 batteries represents an interesting solution for installations where weight, available space, and lifespan are important.

Each battery weighs approximately 18.7 kg, for a total weight of approximately 37.4 kg for the set. The integrated handle facilitates handling during installation or replacement.

150A BMS integrated on each battery

Each battery has its own 150A BMS management system. This device monitors the internal operation of the battery and contributes to its daily protection.

The BMS provides protection against:

• Overcharging
• Excessive discharge
• Overcurrents
• Short circuits
• Abnormal temperatures
• Unsuitable charging conditions
• Cell imbalance

In parallel setup, currents can be distributed between the two batteries if the installation is correctly wired. It is essential to use cables of the same length, same section, and appropriate protections to achieve balanced distribution.
