Lithium PowerBrick+ 12V 250Ah battery

The Lithium-Ion PowerBrick+ 12V-250Ah battery offers great safety through the use of cylindrical cells in Lithium Ferro Phosphate (LiFePO4 or LFP) technology.

The PowerBrick 12V-250Ah integrates in its case an innovative control system (BMS) to ensure a very high level of safety in use. The BMS constantly controls and balances the battery cells, in order to protect the battery and increase its life. The BMS also protects the battery from any mishandling: deep discharge, charging voltage too high, etc.

The PowerBrick+ range has been designed to replace lead-only batteries advantageously, offering a quadrupled energy density for an equivalent weight and footprint.
Due to its technology, the PowerBrick+ 12V-250Ah lithium battery can be installed in any position (vertically, lying on the side or upside down).

The electrical parameters of the PowerBrick+ 12V-250Ah lithium battery are compatible in all respects with those of a 12V AGM lead battery. In the vast majority of cases, the charging system can be kept identical and no additional accessories are needed to perform the replacement.

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

The Lithium PowerBrick + 12V-250Ah battery has a nominal voltage of 12.8V. 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 12V and up to 48V (for 4 packs assembled in series), which meets the needs of almost all electrical applications of traction, solar or wind storage, servitude, robotics, trolleys, etc.

The battery is protected by a waterproof ABS box, resistant to splashes of water and dust (PROTECTION INDEX IP65).

PowerBrick+ products are lightweight, compact, high-performance and can be used for all types of uses and applications. The PowerBrick+ directly replace older generation batteries (VRLA Lead, AGM or OPZ batteries) in 12V, low performance and harmful to the environment (use of heavy metals and complexity of recycling).

The PowerBrick+ range benefits from a commercial warranty of 2 years, expandable to 5 years
