Polar 350Ah under-seat battery incl. Smart BMS with 300A continuous current & BT/WiFi app

Optimum lead-acid battery replacement with up to 10 times the service life
BullTron LifePO4 batteries are an optimum lead-acid battery replacement with all the advantages of lithium iron phosphate batteries.
They offer a weight reduction of up to 85%, high energy reserves and stable voltage even under extreme loads.
The batteries have been specially developed to achieve an optimum ratio of size, weight, performance and service life.
An extremely long service life is guaranteed even with regular deep discharges (3500 cycles at 100% DOD/discharge depth or 6000 cycles at 80% DOD/discharge depth) thanks to the latest lithium technology, making BullTron® batteries the ideal supply battery.

The battery is suitable for 12V systems.

• 12V parallel connection is possible (increase in capacity)
• Series connection 24V, 36V, 48V is also possible (balancer between the individual batteries recommended)

Advantages

• Design, development & assembly in Germany
• Screwed housing (can be opened)
• All cables and electronic components can be replaced (screwed)
• Use of high-quality & durable components
• up to 75% longer cycle life than other LiFePO4 batteries
• up to 45% smaller and up to 35% lighter than other LiFePO4 batteries
• Battery sizes up to 540Ah suitable for under-seat mounting
• Automatic disconnection of the battery in the event of a short circuit

Safest lithium technology (LiFePO4)
BullTron batteries use lithium iron phosphate technology (LiFePO4), currently the safest lithium technology on the market. All batteries consist of powerful and very durable (LiFePo4) cells and an integrated battery management system (BMS). The BMS permanently protects the individual cells and the entire battery against over/under voltage, over/under temperature, overload and short circuit (automatic shutdown without damage).
Premature failure of the battery due to external influences or incorrect use is effectively prevented by the BMS.
