PB+12/7.5
0712971137790
PowerBrick+ lithium battery designed to power 12 V equipment and provide energy storage for light installations (off-grid solar batteries, servitude, emergency power, mobility). It uses LiFePO4 chemistry with cylindrical cells and an integrated BMS, which monitors charging/discharging, temperature and cell balancing. It is particularly suitable when you are looking for a compact, IP65-rated, waterproof battery that is easy to integrate into a small modular system.
- Specifications: 0.10 kWh (12.8 V, 7.5 Ah). Energy efficiency > 98%. 3,000 cycles at 100% DoD @ 1C and 4,500 cycles at 80% DoD @ 1C.
- Cells: cylindrical cells (4S5P architecture) in LiFePO4, designed to provide a stable 12 V power supply over repeated cycles.
- BMS + communication: integrated BMS that measures current, cell voltage and temperature, and controls balancing; BMS cut-off during charging at 14.8 V and BMS cut-off during discharging at 10 V.
- Compatibility + scalability: It allows you to build a modular set of up to 4 batteries in series (up to 48 V) and up to 16 batteries in parallel, in order to increase capacity and autonomy.

PowerBrick+ 12V 7.5Ah Lithium Battery PB+12/7.5
The PowerBrick+ 12V 7.5Ah 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 to 100% of its capacity, this 7.5Ah battery is a cost-effective replacement for a much higher-capacity AGM lead-acid battery (up to 15Ah).
- 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 an innovative 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 (Lead-acid VRLA, 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.

Important notice for our customers in Belgium:An environmental levy of €3.12 excl. VAT must be applied to the purchase of each PowerBrick+ PB+12/7.5 - 7.5 Ah lithium battery. Please add the corresponding product when purchasing this lithium battery. More information at the bottom of the page. |
Flexibility and modularity
The PowerBrick+ system adapts to all your projects, from robotics to solar storage, thanks to simplified scalability:
| Technical Data Sheet: Configurations & Applications | |
|---|---|
| Series connection | Up to 4 units (Final voltage from 12V to 48V) |
| Parallel connection | Up to 15 units (increased Ah capacity) |
| Applications | Electric traction, auxiliary power, marine, solar, wind power. |
Commitment and warranty
PowerBrick+ quality is backed by a 2-year commercial warranty, with the option to extend this to 5 years, ensuring your long-term peace of mind.
Performance and cost-effectiveness
LiFePO4 (Lithium Iron Phosphate) technology offers energy efficiency far superior to conventional batteries.
- Usable energy: Unlike lead-acid batteries (limited to 50%), this battery allows a 100% deep discharge.
- Extremely compact: For the same actual runtime, it is 50% lighter and 40% smaller than a lead-AGM battery.
- Stable power: The voltage remains constant throughout the discharge cycle thanks to virtually zero internal resistance.
- Energy efficiency: Efficiency greater than 98% (negligible Peukert losses).
Safety and built-in intelligence
Equipped with a latest-generation BMS (Battery Management System), the battery manages its own protection and optimisation.
- Ultra-safe chemistry: No risk of fire, explosion or thermal runaway.
- Integrated heating system: Ensures optimal charging and performance even in sub-zero temperatures.
- Bluetooth connectivity: Real-time monitoring via smartphone of State of Charge (SOC), State of Health (SOH) and cell voltage.
Durability and the environment
A sustainable investment designed to last for over a decade.
- Exceptional longevity: Over 3,000 cycles, equating to a lifespan of more than 10 years with regular use.
- Minimal self-discharge: Less than 3% loss per month in storage.
- Eco-design: Free from lead, acid and rare metals. No toxic outgassing.
