PowerBrick+ 12V 70Ah Lithium Battery PB+12/70
The PowerBrick+ 12V-70Ah battery delivers an impressive 0.90 kWh of energy in a compact design. Utilising Lithium Iron Phosphate (LiFePO4) technology, it offers exceptional runtime and constant voltage stability, far surpassing the performance of traditional lead-acid batteries for demanding applications.
Increased capacity and impressive lightness
- 0.90 kWh energy: A 70Ah power reserve ideal for deep and prolonged discharge cycles.
- High performance: Thanks to the ability to discharge to 100% of its capacity, this 70Ah battery is a cost-effective replacement for a 140Ah to 150Ah AGM lead-acid battery.
- Robust IP65 design: Its waterproof ABS casing protects the battery from dust and water splashes, ensuring maximum reliability in marine or outdoor environments.
Intelligence and safety: The integrated BMS
Each battery features an innovative battery management system (BMS) that ensures the protection and health of the cells:
- Active protection: Safeguards the battery against overcharging, over-discharging and short circuits.
- Continuous balancing: Optimises the charge of each cell individually to maximise the battery pack’s lifespan.
- Intrinsic safety: LiFePO4 chemistry is stable and non-flammable, ensuring use without risk of explosion.
Universal "Plug & Play" installation
Upgrade your system effortlessly. The PowerBrick+ is designed to be directly interchangeable with older batteries (VRLA lead-acid, AGM, Gel):
- Electrical compatibility: Fits perfectly with your existing 12V chargers.
- Versatile mounting: Its sealed technology allows installation in any position.
- Environmentally friendly: Free from acid and heavy metals, it facilitates recycling and complies with environmental standards.
