Integrated BMS for safe use

Each battery has its own BMS 150A. This management system helps protect the cells and stabilize the overall operation.

The BMS provides protection against:

• Overcharging
• Excessive discharge
• Overcurrents
• Short circuits
• Abnormal temperatures
• Unsuitable charging conditions
• Internal imbalances

For series or parallel setup, it is important to use identical batteries, at the same charge level, with appropriately sized cables and correctly dimensioned electrical protections.

Installation tips

• Check the charge status of the 4 batteries before connection.
• Use only identical batteries in the same setup.
• Provide appropriate fuses or circuit breakers on each battery line.
• Use cables of the same length and cross-section in parallel.
• Use a charger, solar regulator, or DC-DC charger compatible with LiFePO4.
• Do not use a lead charger with desulfation or equalization mode.
• Respect polarity during wiring.
• Install the batteries in a stable, dry, and ventilated location.
• Do not immerse the batteries despite the IP65 rating.
• Do not use these batteries as engine starter batteries.
• Adapt the converter to the final voltage of the battery bank: 12V, 24V, or 48V.
