PowerBrick® Lithium Ion battery 12V-40Ah - LiFePO4
This Lithium-ion 12V-40Ah battery has been designed thanks to the know-how of PowerTech Systems, french company specialized in the conception of high performance lithium-ion batteries.
Safety
The PowerBrick® 12V-40Ah battery offers a high level of safety through the use of cylindrical cells using Lithium Iron Phosphate LiFe (LiFePO4) technology. the battery embeds an innovative control system (BMS, Battery Management System) that ensures a very high level of safety during operation. The BMS constantly monitors and balances the cells of the battery. BMS also protects battery from misuse and increases its lifespan.
The 12V-40Ah lithium battery is protected by a waterproof ABS case that resists to water projection and dust (IP55 for PowerBrick® STANDARD battery or IP65 for PowerBrick® PRO+ version).
Designed for Drop-In replacement of lead-acid batteries
The PowerBrick® product line has been designed to replace lead-acid batteries. It offers high energy density, for a low weight and a small space requirement.
The electrical parameters of PowerBrick® are compatible in all respects with those of a 12V lead-acid battery. There is almost never need to replace original charger to use a PowerBrick®, as soon as the charger is delivering voltage within the product specification.
Caution : This battery is a traction or utility battery designed to deliver high levels of current. It may not be suitable for starting an internal combustion engine.
If you nevertheless have to crank an internal combustion engine, check that the current level of the starter motor is compatible with the maximum current that the battery can deliver.
If you are looking for a dedicated engine start battery, please see the PowerStart product range.
Easy installation
Each PowerBrick 12V-40Ah lithium battery has a nominal voltage of 12.8V. It can be connected in series (up to 4 batteries in series) and in parallel (up to 16 batteries for PRO version). Thanks to its technology, the PowerBrick 12V-40Ah battery can be installed in any position (lying on the side, upside down, etc.).
The final assembly voltage can be from 12V, up to 48V (with 4 elements in series). This covers almost most common electrical applications (traction, solar storage, wind power).
For an application with a voltage greater than 75VDC, the installer must be trained to the risks of low voltage (LV)
The 12V-40Ah LFP battery pack is ideal for wind and solar energy storage, AGV (automated guided vehicle), marine, boats, traction, small EV, forklifts, robotics, and much more...
Lithium Iron Phosphate (LiFePO4) batteries have a lower ecological footprint
The PowerBrick® 12V-40Ah is designed to drop-in replacement of old generation Lead acid batteries. VRLA and AGM batteries provides poor performances and are harmful for the environment through the use of heavy metals and acid electrolytes.

Compacte,légère , mais j’ai du changer les cosses de mon minn kota pour adapter à la batterie.
Serait intéressant que les ingénieurs puissent trouver des cosses adaptables.

J’ai besoin d’une batterie pour faire fonctionner ma monture de télescope CGX-L. Cette batterie de 40 Ah convient parfaitement. Elle ne fait que 5 kg. Pour une même utilisation, une batterie au plomb (qui ne peut se décharger qu’à 50%) ferait 80 Ah pèserait 20 kg.
La tension maxi de 13,8 volts qui correspond à la batterie pleine est sans inconvénient. La monture fonctionne fort bien.
