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.

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

Do i need to recharge battery immediately after operation ?

PowerBrick^® lithium-ion 12V 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.

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^® Lithium battery, 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 14.6V (for a 12V battery)
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 14.6V (for a 12V battery)
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^® 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

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

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.

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 14.8V
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.

How to place Lithium-Ion batteries?

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.

Produit conforme aux promesses du fabricant. La batterie et légère et relativement compacte. La capacité mesurée est en fait un peu supérieure à celle annoncée (58Ah mesuré avec mon BatteryTester 2100).
Les poignées de transport sont réellement pratiques. Le BMS joue bien son role, j’ai pu m’en rendre compte avec mon camping car alors que j’avais laissé les lumières extérieures allumées durant la nuit. Le BMS coupe pour éviter d’endommager la batterie. C’est juste simple, facile à utiliser et sans prise de tête. C’est comme une simple batterie au plomb à part que c’est plus léger et plus petit.
Avec le recul, j’aurais du prendre le modèle 100Ah car 55Ah est vraiment juste pour mon application.

Very good product, I replaced my 12V 110Ah AGM battery with the powerbrick 55 and the result is amazing !
Full power during entire discharge. deep discharge is allowed and BMS cuts-off before falling to very high discharge. I use it for my electric powered fish boat and enjoy the lightweight when it’s time to carry it back to home.
I set a 5 start rate for this product.
Best Regards, Matthew

Hi,
After talking on the phone with the salesman who is really nice, he advised me to take a battery smaller than the 12V 100Ah I was looking for, given my low consumption per day.
He explained to me that lithium iron phosphate batteries can be 100% discharged while keeping a very long life.
The efficiency of these new batteries being much better (95% instead of 70%), the energy recovered by the solar panel is greater, gain of minimum 30%.
After installation in place of the old battery without any particular difficulty, I am satisfied for the moment.
In the end I took a battery 12V 55Ah which is enough for me.
Recharging by the alternator is done super fast.
So much for my feedback.
Sincerely
