WARNING!
Short circuits, too deep discharges and too high charge currents will damage the battery

Always install an external safety relay!
Never charge a battery:
- when the safety relay has cut out;
- after it was discharged below the Battery Safety voltage;
- when the battery is damaged;
- when the battery was overcharged.
If in doubt, contact your supplier or Mastervolt.
