Ultimatron ULS-12V-115Ah LiFePO4 Versorgungsbatterie

Ultimatron LiFePO4 12.8V 115Ah – Lithium Auxiliary Battery in Original Size for VW California T5/T6

This lithium battery precisely replaces the original auxiliary battery of the VW California T5 and T6. The casing matches the original format 1:1 – it fits directly into the existing battery compartment without modifications and is therefore fully compatible with the factory wiring.

With a true lithium capacity of 115Ah, it offers nearly three times the usable energy compared to the standard AGM or gel battery (approximately 36–40Ah usable). Ideal for longer standstill periods, self-sufficient camping, and the use of electrical appliances without shore power.

The battery features an integrated BMS (Battery Management System) as well as a heating function that allows for safe charging even in sub-zero temperatures. All operational data such as voltage, state of charge, and temperature can be monitored via Bluetooth through an app.

Advantages at a glance:

• Fits VW California T5 and T6 – no adjustments needed 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
• Weighs only 11 kg

Perfect for anyone looking to upgrade their California to lithium – simple, effective, and perfectly detailed.

* A charging booster is required when converting from AGM to LiFePo4 technology. Cables and fuses should be checked accordingly.
