PowerBrick+ 48V 25Ah lithium battery PB+48/25

48V 25Ah LiFePO4 Lithium battery - PowerBrick+ : Autonomy and safety

The PowerBrick+ 48V-25Ah lithium-ion battery offers maximum safety thanks to the use of cylindrical cells in Lithium Ferro Phosphate (LiFePO4 or LFP) technology.

The PowerBrick 48V-25Ah incorporates an innovative control system (BMS) in its casing, ensuring a very high level of safety during use. The BMS constantly monitors and balances the battery cells, to protect the battery and extend its life. The BMS also protects the battery from mishandling: deep discharge, overcharging, etc.

The PowerBrick+ range has been designed to replace lead-acid batteries, offering quadruple the energy density for the same weight and size.
Thanks to its technology, the PowerBrick+ 48V-25Ah lithium battery can be installed in any position (upright, on its side or upside down).

The electrical parameters of the PowerBrick+ 48V-25Ah lithium battery are fully compatible with those of a 48V AGM lead-acid battery. In the vast majority of cases, the charging system can be retained unchanged, and no additional accessories are required for replacement.

Since a PowerBrick+ battery can be discharged to 100% of its capacity, a lead-acid AGM battery can be replaced by a PowerBrick+ with a capacity 2x lower than that of the lead-acid battery (e.g.: a PowerBrick+ 50Ah replaces a 100Ah AGM battery).

The PowerBrick+ 48V-25Ah lithium battery has a nominal voltage of 51.2V. It can be easily assembled in series (up to 4 batteries in series) and in parallel (up to 15 batteries).

The voltage of the final assembly can be 48V and up to 192V (for 4 packs assembled in series), which meets the needs of almost all electrical applications for traction, solar or wind storage, service, robotics, carts, etc.

The battery is protected by a splash-proof, dust-proof ABS case (IP65).

PowerBrick+ products are lightweight, compact, high-performance and can be used for all types of applications. PowerBrick+ directly replaces old-generation batteries (VRLA, AGM or OPZ lead-acid batteries) in 48V, which are inefficient and harmful to the environment (use of heavy metals and complexity of recycling).

The PowerBrick+ range comes with a 2-year commercial warranty, extendable to 5 years.
