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,

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^® battery in the same way. You may use the same cables to reconnect PowerBrick^® battery.

PowerBrick^® lithium-ion 12V, 24V or 48V 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.

The PowerBrick® battery is a traction or utility battery designed to deliver high levels of current.
Depending on the type and displacement of the engine, the battery may not be suitable for starting the engine.
Check that the starter current level 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.

Alternator are usually regulated and provide a voltage between 14.2V and 14.8v when operating.
PowerBrick^® battery has a built-in BMS that is able to limit charge current when voltage is greater than 14.4V : unlike conventional Lithium starter batteries, the BMS does not immediately cut-off charge as soon battery is reaching maximum voltage, but it will decrease incoming current using a PWM (Pulse Width Modulation) device until battery is totally charged and balanced.

This innovative BMS system allow full protection and charge, even if alternator is not properly regulated or if it delivers a slightly voltage greater than battery max charge voltage.

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^® Lithium battery, but some customers prefers using a Lithium charger to keep a better lifespan.

Several charging sources are possible:

PowerBrick^® batteries using Lithium-Iron-Phosphate technology and equipped with advanced BMS system, offer the following features:

Once this number of cycles has been completed, the battery will still be able to deliver about 80% of its initial energy.

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.

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 : Balancing features :

The PowerBrick^® products are designed around an assembly of sealed cells. There is no risk of electrolyte leak. The whole of the block cells and embarked electronics is firmly fixed in the battery casing.

All our batteries can be placed in any positions (tilted or lying). There is no obligation to install them upright, as for the conventional batteries in Lead/AGM.
