Batterie Lithium-Ion 24V-150Ah - PowerBrick

The Lithium-Ion PowerBrick battery 24V-150Ah offers high level of safety through the use of cylindrical cells in Lithium Ferro Phosphate technology (LiFePO4 or LFP).

PowerBrick 24V-150Ah integrates an innovative Battery Management System (BMS) in its casing to ensure a very high level of safety in use. The BMS constantly monitors and balances the battery cells to protect the battery and increase its life. The BMS also protects the battery from any misuse: deep discharge, high charging voltage, etc.

The PowerBrick range has been designed to replace lead-acid batteries advantageously, by offering a quadrupted energy density for an equivalent weight and size.
Thanks to its technology, the lithium battery PowerBrick 24V-150Ah can be installed in any position (vertically, lying on the side or head down).

The electrical parameters of the PowerBrick lithium battery 24V-150Ah are compatible in all respects with those of an AGM lead battery of 24V. In the vast majority of cases, the charging system can be kept the same and no additional accessories are required to perform the replacement.

Given PowerBrick can be 100% discharged, a lead acid or AGM battery can be replaced by a PowerBrick with half the capacity of lead acid battery (ie: PowerBrick 50Ah can replace a AGM 100Ah battery).

The PowerBrick Lithium battery 24V-150Ah has a nominal voltage of 25.6V. It can be easily assembled in series (up to 4 PowerBrick 12V in series, or 2 PowerBrick 24V in series) and in parallel (up to 16 PowerBrick in parallel).

The battery is protected by a waterproof ABS case, splash and dust resistant (Protection index IP65).

The products PowerBrick are light, compact, efficient and can be used for all types of uses and applications. PowerBrick are designed to drop-in replacement of old generation batteries (Lead VRLA, AGM or OPZ batteries) in 24V, that are low performance and harmful to the environment (use of heavy metals and acid electrolytes).

The PowerBrick range benefits of a 2-year commercial guarantee, extendable to 5 years

Frequently Asked Questions

How safe are Lithium-Ion PowerBrick+ batteries ?
PowerBrick+ batteries are using Lithium Iron Phosphate chemistry (LFP) that is one of the most safe Lithium-Ion technology. This chemistry is not subject to thermal runaway, is non-flammable and is considered as non-hazardous by international regulation standards.

Each battery is fitted with a high quality Battery Management System (BMS) that ensure a safeguard role during battery operation. The BMS is designed to deliver high power in complete safety for a very large spectrum of applications,
What can i use PowerBrick+ battery for ?
PowerBrick+ batteries are commonly used for Marine, Recreational vehicles, Golf Cart applications, CCTV, robotics, PV energy storage, etc..

PowerBrick+ Battery can be used for any system or application that would normally use Lead acid battery (AGM, GEL) in 12V, up to 48V. After removing your old batteries, place PowerBrick+ batterie in the same way.

You may use the same cables to reconnect PowerBrick+ battery.
Do i need to recharge battery immediately after operation ?
PowerBrick+ batteries can be partially charged or discharged unlike Lead Acid batteries that needs to be fully charged after use or before storage.

For instance, you can leave your battery half charged for some weeks without any issue.

If you plan to store battery for a long period (> 2 month), you need to charge battery at minimum 25% of SoC (State of Charge) before storage. It is necessary to check battery voltage every 6 month during storage.
How do I charge a PowerBrick+ Lithium-ion battery ?
PowerBrick+ lithium ion technology uses the latest and most advanced built-in battery management system (BMS) to monitor and prevent damage to the battery during use.

You may utilize a Lead-acid charger with PowerBrick, but some customers prefers using a Lithium charger to keep a better lifespan.

Several charging sources are possible:
  • Alternator: Most alternators (marine, RV, cars) will efficiently charge PowerBrick+ lithium ion technology as soon alternator charge voltage is between 14.0V and 14.8V
  • Conventional Lead-Acid battery charger: PowerBrick+ Battery Management System (BMS) is designed to be compatible with standard chargers. You need to check that charger has a built-in CC/CV charge algorithm (Constant Current / Constant Voltage) and charger maximum voltage is comprised between 14.0V and 14.8V
  • Lithium-Ion charger: This is the best way to charge PowerBrick+ Lithium-ion battery. These chargers embeds some dedicated charge algorithm with precise charge voltage. It also manage efficiently charge floating voltage and duration in order to maximize battery life span.
How long does a PowerBrick+ battery last ?
PowerBrick+ advanced lithium-ion technology will provide you with 4500 complete charge and discharge cycles at 80% DoD (Depth of Discharge). After 4500 cycles, you will still have over 80% of usable energy left.

In case you discharge PowerBrick+ at 65% DoD rate, you can expect to get about 10000 cycles.
  • Example 1: One PowerBrick+ 12V-100Ah battery, after being discharged at 80% DoD for 4500 cycles, is now a 12v 80ah battery.
  • Example 2: One PowerBrick+ 12V-100Ah, after being discharged at 65% DoD for 10000 cycles, is now also a 12v 80ah battery.
In term of time duration, If you discharge 80% of the PowerBrick+ and then recharge it every day, 7 days a week for more than 10 years, you will still have 80% of usable battery energy left.

This is a large improvement in lifespan compared to a conventional Lead Acid battery (AGM, Gel) rated at 500-800 cycles for 50% DoD cycles.
What is the Battery Management System (BMS) and how does it work ?
Each PowerBrick+ embeds a built-in BMS. This BMS is a high-tech design that manage two main aspects of battery during operation : Protection features :
  • Low Voltage Protection Switch – Automatically disconnects at 10.0V
  • Over Voltage Protection Switch – Automatically disconnects at 15.0V
  • Short Circuit Protection Switch – Automatically and safely disconnects battery
  • Reverse Polarity Protection Switch – Automatically and safely disconnects battery
  • Over temperature – Automatically shut-down battery until normal temperature recovery
Balancing features :
  • Internal cell balancing – Automatically balances PowerBrick+ cells during battery operation. Balancing algorithm has been developed to ensure perfect balance between cells throughout battery life.
  • Charge Balancing – for PowerBrick+ connected in parallel and/or in series, the BMS will balance each PowerBrick+ independently, in order to provide a constantly balanced battery system.
