PowerBrick+ Smart BT 12V 135Ah lithium battery PB+BT12/135

The PowerBrick 12V-135Ah "Smart BT" lithium-ion battery offers a high level of safety thanks to the use of cylindrical cells in Lithium Iron Phosphate (LiFePO4 or LFP) technology.

The PowerBrick 12V-135Ah "Smart BT" 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 12V-135Ah "Smart BT" lithium battery can be installed in any position (upright, on its side or upside down).

The electrical parameters of the PowerBrick 12V-135Ah "Smart BT" lithium battery are fully compatible with those of a 12V AGM lead 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 an AGM 100Ah battery).

The PowerBrick 12V-135Ah "Smart BT" lithium 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 virtually 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 12V batteries (VRLA, AGM or OPZ lead-acid batteries), which are inefficient and harmful to the environment (use of heavy metals and complex recycling).

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