Lithium-Ion-Battery BTLi 12-100B BTLi 12-120B


The batteries of the BTLi series are maintenance-free lithium-ion rechargeable batteries (LiFePO4) with a service life expectancy of >5000 cycles and only 40% of the weight of lead-acid batteries. They use a built-in Battery Management System (BMS) for maximum reliability. Excellent for camping, outdoor and caravan but also e.g. for UPS systems, DC power supplies, security systems and as solar or wind energy storage.

The BTLi 12-120B and BTLi 12-100B also have a built-in Bluetooth interface, which can be used to monitor the charge level and battery status at any time via Android or IOS app.
