Ultimatron Heat Pro 200Ah 12V battery for Caravan & Motorhome
Lithium battery with a capacity of 200Ah for caravan, motorhome or boat with a built-in heating system, allowing it to be charged even during winter. With a continuous discharge capacity of 200A, it is also suitable for inverters up to 2000W. Ultimatron Heat 200Ah features a BMS (battery management system) that protects the battery against incorrect charging, high temperatures and overload. Thanks to its BMS, you can replace your lead-acid battery (not starter batteries) directly without making any adjustments to the electrical system. The battery can also be connected in parallel with up to 4 batteries for increased capacity.
READ MORECapacity: 200 Ah (2560 Wh)
Output capacity: 12V/200 A (approx. 2500W)
Nominal voltage: 12.8V
Weight: 21.3 kg
Lifespan: approx. 15 years (6000 cycles at 80%)
200Ah Lithium Battery for Caravan and Motorhome – Operates in Sub-zero Temperatures
Battery with high capacity, low weight, compact size and significantly longer lifespan than a traditional lead-acid battery. The advantage of a lithium battery is that it charges much faster than a conventional battery, and you can use almost the entire battery capacity compared to around 50% from a traditional battery. This means that this battery corresponds to approximately 300Ah in traditional batteries, at a significantly lower weight and smaller size.
A unique feature of this LiFePO4 battery from Ultimatron is its built-in heating system, which heats the battery before charging when needed. This makes it especially suitable for those who use their caravan/motorhome even during the colder parts of the year. The battery has an integrated BMS (Battery Management System) for maximum safety and lifespan. Thanks to the built-in electronics, the battery can be charged via a standard constant voltage charger, solar charge controller, etc.
Bluetooth
The BMS also has a Bluetooth connection, allowing you to connect it to your phone to monitor the battery status. There you can see:
- State of charge
- Voltage
- Available capacity
- Number of charge cycles
- Temperature and battery health status
Ultimatron Heat 200Ah Lithium Battery for Caravan/Motorhome
- Drop-in replacement – no external components required
- Built-in heating system for charging even in sub-zero temperatures
- Bluetooth connection – connect to app to read battery status
- Designed to replace a traditional battery (equivalent voltage and terminal connections)
- Long lifespan – 15 years under normal use (5–10 times longer than a traditional lead-acid battery)
- Low weight (save approx. 60 kg)
- High capacity – actual usable capacity equivalent to a 300 Ah lead-acid battery
- Environmentally friendly
- Built-in protection via BMS (Battery Management System)
- The system automatically balances the cells, extending battery lifespan (often what distinguishes high-quality from low-quality lithium batteries).
- 3–10 times faster charging

Which chargers/solar panels are compatible with the battery
Ultimatron’s BMS supports virtually all battery chargers and solar panels and works directly with the motorhome/caravan charger. It supports all external chargers that provide a steady current during charging. With so-called smart chargers that pulse the current to recondition lead cells/maintenance charge, the BMS will shut off charging. However, many smart chargers can be set to a non-pulsating charging mode. For those charging via solar panels, the battery supports up to 100A.
