Ultimatron Heat 200Ah 12V battery for Motorhomes
Lithium battery with integrated heating system specially designed for installation under the seat of Fiat Ducato, Citroën, Peugeot etc. The heating system allows charging even in winter. The Ultimatron Heat 200Ah has a BMS (Battery Management System) that ensures and protects the battery from 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 to increase capacity.
READ MORECapacity: 200 Ah (2560 Wh)
Output capacity: 12V/150 A (approx. 1900W)
Nominal voltage: 12.8V
Weight: 23.3 kg
Lifespan: approx. 15 years (6000 cycles to 80%)
200Ah Lithium Battery for Under-Seat Installation
High-capacity battery with low weight, compact size, and significantly longer lifespan compared to traditional motorhome batteries. A unique feature of this LiFePO4 battery from Ultimatron is the built-in heating system, which warms the battery before charging when needed. Perfect for those who use their motorhome during the colder seasons. Lithium batteries also charge much faster and can utilize nearly the entire capacity, unlike traditional batteries which typically use about 50%. This makes it equivalent to about 300 Ah in traditional batteries—at a much lower weight and smaller size.
The battery includes a built-in BMS (Battery Management System) for maximum safety and longevity. Thanks to the internal electronics, it can be charged using a standard constant-voltage charger, solar regulator, etc.
Bluetooth
The BMS also includes a Bluetooth connection, allowing you to check battery status on your phone. You can monitor:
- Charge status
- Voltage
- Available capacity
- Number of charge cycles
- Temperature and battery health

Compatible chargers / solar panels
The BMS in Ultimatron supports virtually all chargers and solar regulators and connects directly to the camper's built-in charger. It works with any charger that delivers a stable current. With so-called smart chargers that pulse for reconditioning lead batteries, the BMS will shut off charging. Many smart chargers can be set to non-pulsing mode. For solar, the battery supports up to 80A.
