- 300 A continuous and 1,000 A peak current
- Integrated heating: charging down to −30 °C
- Dual BMS with 5 A active balancer
- Bluetooth and Wi-Fi app for state of charge and cell voltages
- Integration into philippi P-BUS and the PCU Control Unit

In the philippi on-board system.
All BullTron Polar batteries can be integrated into the philippi P-BUS system. The philippi Control Unit PCU then shows the battery’s state of charge, voltage, current, cell voltages and temperature on its touch display, together with tanks, energy flow and loads. You see and control the battery and on-board system in one place.
Frost-proof charging.
The heating elements surround the cells and start below 0 °C as soon as charging current is present, at up to 10 A or 150 W. The heat goes straight into the cells, so according to the manufacturer the battery charges down to −30 °C. Without charging current the heating stays off; self-discharge is about 1 to 3 % per month.
Lots of energy under the seat.
The under-seat format uses the space beneath the driver or passenger seat. A dual BMS and 300 A continuous current also supply large inverters, and the battery can be installed upright or lying down.
Made by BullTron, supported by philippi.
BullTron develops and assembles its LiFePO4 batteries in Germany. The screwed housing can be opened, and BMS, balancer and heating are replaceable. philippi is a BullTron wholesaler in Remseck am Neckar and advises on selection, installation and conversion: +49 7146 87 44 0.
In the philippi P-BUS system
All BullTron Polar batteries can be integrated into the philippi P-BUS system. The philippi PCU Control Unit then shows state of charge, voltage, current, cell voltages and temperature. The connection is made with our BullTron P-BUS adapter: a plug-and-play cable, about 30 cm long, with an integrated T-piece for further P-BUS devices.

Frequently asked questions. Answered briefly.
Can I charge the BullTron Polar Untersitz 12 V 540 Ah in frost?
Yes. The integrated heating starts below 0 °C as soon as charging current is present and warms the cells evenly from the outside. According to the manufacturer, the battery thus charges at temperatures down to −30 °C. Without charging current the heating stays off and does not drain the battery while parked or in winter storage.
Can the battery be connected to the philippi PCU?
Yes. All BullTron Polar batteries can be integrated into the philippi P-BUS system. The PCU Control Unit then shows state of charge, voltage, current, cell voltages and temperature on its touch display, together with tanks and loads. The BullTron app via Bluetooth and Wi-Fi also remains available, for example for settings.
Can I simply replace my lead-acid or AGM battery?
According to the manufacturer, a one-to-one swap for lead-acid, GEL or AGM batteries is possible without changing the chargers. Still check whether your chargers offer a LiFePO4 profile with a charge voltage of 14.2 to 14.6 V. philippi in Remseck advises you on the conversion on +49 7146 87 44 0.
