PowerBrick+ 12V 12Ah Lithium Battery PB+12/12

The PowerBrick+ 12V-12Ah battery represents the new generation of energy storage. Designed using Lithium Iron Phosphate (LiFePO4) technology, it outperforms traditional batteries in terms of performance, durability and safety.
A powerhouse of performance and lightness
- Four times the energy density: Enjoy significantly longer runtime with the same footprint as a lead-acid battery.
- 2-for-1 replacement: Thanks to its ability to discharge to100%of its capacity, this 12Ah battery is a cost-effective replacement for a much higher-capacity AGM lead-acid battery.
- Flexible installation: Its sealed design allows installation in any position (upright, on its side or upside down).
Intelligence and safety: The integrated BMS
Each battery features aninnovative management system (BMS) that acts as an electronic brain to ensure total reliability:
- Active protection: Prevents damage caused by deep discharges or excessive charging voltages.
- Continuous balancing: Optimises the charge of each cell to maximise battery life.
- Intrinsic safety: LiFePO4 chemistry is stable and non-flammable, eliminating any risk of explosion or fire.
Plug & Play compatibility
Upgrade your system effortlessly. The PowerBrick+ is designed to be directly interchangeable with older batteries (VRLA lead-acid, AGM, OPZ):
- Electrical compatibility: Works perfectly with your existing 12V chargers.
- Eco-friendly: Free from heavy metals and acid, it facilitates recycling and protects the environment.
- IP65 protection: Its robust ABS casing is resistant to dust and water splashes.
