Installation tips

• Choose a unique architecture: 24V or 48V depending on the equipment used
• Use only chargers, regulators or inverters compatible with LiFePO4
• Balance the batteries before any series or parallel assembly
• Install DC fuses or circuit breakers adapted as close as possible to the battery bank
• Size the cables according to the current, length and allowable voltage drop
• Do not mix with lead batteries or batteries of another model
• Do not connect a wind turbine, solar panels or a generator directly without appropriate regulation
• Provide a ventilated, protected and accessible location
• Have the installation validated by a professional for any high-power installation

Why choose the set of 4 batteries?

• To create a large capacity lithium storage
• To power an autonomous system for longer
• To build a 24V very long autonomy bank
• To achieve a 48V architecture suitable for compatible inverters
• To reduce clutter compared to an equivalent lead park
• To have Bluetooth monitoring on each battery
• To prepare a more robust solar or hybrid installation

Important precautions

• Do not use as an engine starter battery
• Do not immerse despite IP65 rating
• Do not charge with a non-compatible lead charger LiFePO4
• Do not exceed the permissible currents
• Do not perform a 96V assembly if the maximum announced series configuration is limited to 2S
• Check the compatibility of all equipment before connection

Contents of the lot
