Ultimatron LiFePO4 12.8V 115Ah – Lithium auxiliary battery in original dimensions for VW California T5/T6

This lithium battery is a perfect replacement for the original auxiliary battery in the VW California T5 and T6. The housing is an exact match to the original dimensions – it fits into the existing battery tray without any modifications and is therefore directly compatible with the standard wiring.

With a true lithium capacity of 115Ah, it offers almost three times the usable energy compared to a standard AGM or gel battery (approx. 36–40Ah usable). Ideal for extended periods of inactivity, off-grid camping, and the use of electrical appliances without shore power.

The battery features an integrated BMS (battery management system) and a heating function , enabling safe charging even in sub-zero temperatures. All operating data, such as voltage, state of charge, and temperature, can be viewed via Bluetooth using an app.

Advantages at a glance:

  • Suitable for VW California T5 and T6 – no modifications required to place the battery*

  • Approximately three times the usable capacity compared to the original battery

  • Integrated heating system for winter operation

  • Bluetooth monitoring via smartphone

  • Weight only 11 kg

Perfect for anyone who wants to convert their California to lithium – simple, effective and a perfect fit down to the last detail.

* A charging booster is required when converting from AGM to LiFePO4 technology. Cables and fuses must be checked accordingly.
