What is in the kit

  • BullTron Polar 185 Ah: LiFePO4 battery with 12.8 V, built-in heating for charging in the cold and a P-BUS connection for the Control Unit PCU.
  • Charge booster DCB 12V: charges the lithium battery while driving with its own charging curve and limits the current the alternator has to deliver.
  • Class T fuse 200 A with holder: the main fuse directly at the positive terminal, with a high breaking capacity for the short-circuit current of a lithium battery.
  • Battery main switch XD1: disconnects the battery from the electrical system during downtime and in the event of a fault.

With or without shore power charger

If your existing charger has a lithium charging curve and its float charge can be switched off, kit 1 is enough. Otherwise choose kit 2 with the ACE 12/44 charger, whose charging program for lithium batteries can be selected on the control panel.

Does the kit fit my electrical system?

The kit is designed for 12 V electrical systems with an alternator. The fuse depends on the cable cross-section: the cable configurator calculates the right value. The article Converting from AGM to lithium explains the conversion step by step.
