Protection

The balancer evens out the voltage of the six cells. It does not disconnect the pack on over-charge, over-discharge or over-current. Use a fuse, and a charger and load suited to the pack's limits.

Charging and voltage

This pack is designed for 12V vehicle systems. Six 2.3V cells in series give a nominal 13.8V. The charge cut-off voltage of 17.4V (2.9V per cell) is a limit, not a voltage to charge to for use in a vehicle.

• Charge the pack with a 13.8V charger. A 13.8V source stays well below the 17.4V charge cut-off, so the usable capacity may be lower than the nominal figure.
• Direct connection to a vehicle alternator has not been confirmed. The alternator's charging voltage and current must be checked for your vehicle first. To charge from the engine, a current-limited DC-DC charger suited to 6S LTO packs is recommended.
• Do not charge the pack to 17.4V with another charger and then connect it to 12V equipment. A fully charged pack is at a higher voltage than many 12V systems accept. Check the maximum voltage of your equipment first.
• Do not discharge below 9V. The pack will not stop discharging by itself.
