Lithium Ion battery 12V-7.5Ah - LiFePO4 - PowerBrick®
This Lithium-ion 12V-7.5Ah 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-7.5Ah 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-7.5Ah lithium battery is protected by a waterproof ABS case that resists to water projection and dust (IP55 for PowerBrick® STANDARD battery or IP66 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.
Easy installation
Each PowerBrick 12V-7.5Ah 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 10 batteries). Thanks to its technology, the PowerBrick 12V-7.5Ah 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-7.5Ah 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-7.5Ah 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.

Frequently Asked Questions - PowerBrick® product line
What are the differences between PowerBrick® Standard and PowerBrick® Pro version ?
The main differences between the professional range (PowerBrick® Pro+) and the consumer range (PowerBrick® Standard) are:
- The Standard range uses high quality LiFePO4 Lithium cells which allow to reach 2000 cycles at 100% depth of discharge at 1C.
- The PRO+ range uses a new generation of Lithium cells, with better performance. These cells allow to reach 4500 cycles at 80% DoD.
In addition, these cells are sorted and matched for the constitution of the pack. This guarantees a homogeneous ageing over time and better performances. - The Pro+ range uses a more robust embedded BMS that allows higher power levels than the Standard range. This is particularly useful for applications using high inrush currents (starting an electric motor, accelerating a vehicle, starting a microwave oven, refrigerator, air conditioning, etc.)
- Different IP (International Protection) level of the product enclosure.
- Limitation on the number of battery that can be assembled in series and / or parallel.
- Higher energy efficiency for the PRO+ range
- Warranty period limited to 2 years on the standard range, 5 years for the professional range.
All datasheets are available for each product, making it possible to compare the performances of the different products.
For example, here are the differences between the two ranges for the PowerBrick 12V-100Ah:
 PowerBrick Standard |  PowerBrick Pro+ + matched cells | |
| Operation Life | 3000 Cycles at 80% DoD | 4500 Cycles at 80% DoD |

How long does a PowerBrick® battery last ?
PowerBrick® batteries using Lithium-Iron-Phosphate technology and equipped with advanced BMS system, offer the following features:
- PowerBrick Standard: 2000 charge-discharge cycles at 100% DoD (depth of discharge). 3000 Cycles at 80% DoD
- PowerBrick Pro+ : 3000 charge-discharge cycles at 100% DoD (depth of discharge). 4500 Cycles at 80% DoD
- Example #1: A PowerBrick Pro+® 12v-100Ah, after being discharged at 80% DoD during 4500 cycles, is now a 12V battery with a capacity of 80Ah.
- Example #2: A PowerBrick Standard® 12v-100Ah, after being discharged at 100% DoD during 2000 cycles, is now a 12V battery with a capacity of 80Ah
In term of time duration, If you discharge 80% of the PowerBrick® and then recharge it every day, 7 days a week for height years, you will still have 80% of usable battery energy left. This is a large increase in lifespan compared to a conventional Lead Acid battery (AGM, Gel) rated at 500 cycles for 50% DoD cycles.
