Choose the load curve

• It is important to choose the correct charging curve, adapted to the battery
technology. A wrong choice can cause irreversible damage. In particular, there
is a risk of overheating and harmful gases in the event of overvoltage on the
battery.
The LITHIUM charging cycle is only compatible with LiFePo4 batteries with integrated
BMS (Battery Management System).

Maintenance

If necessary, the fuses must be replaced by identical products.
This booster cannot be disassembled and the electronic board is inaccessible.
Therefore, with the exception of the fuses, all on-site maintenance is prohibited.

Battery precautions

• Disconnect the DC power supply before servicing, cleaning or working on
circuits connected to the DC/DC booster.
• Once disconnected, isolate the battery connection terminals.

Chemical and gas risks

• It is important to ensure that the area around the batteries is well ventilated. The
gas produced by the batteries can be explosive. Protect the eyes of all persons
in the vicinity of the batteries. Ensure adequate ventilation to avoid accumulation
of harmful and/or dangerous gases. Do not smoke, use open flames or cause
sparks near the batteries at any time.
• It is important to make sure that the battery voltage matches the output voltage
of the DC/DC booster.
• It is important to make sure that no corrosive products come into contact with
the eyes or skin when working on the batteries.
• Always remove metal objects from hands, wrists and neck, such as rings,
bracelets, watches or necklaces.
• Always work with ungrounded battery. If necessary, the battery ground
connections should be made last.
