Description
Lithium Ion battery 24V-50Ah - LiFePO4 - PowerBrick®
This Lithium-ion 24V-50Ah 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® 24V-50Ah 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 24V-50Ah 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 24V 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 24V-50Ah lithium battery has a nominal voltage of 25.6V. 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 24V-50Ah battery can be installed in any position (lying on the side, upside down, etc.). The final assembly voltage can be from 24V, up to 96V (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 24V-50Ah 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® 24V-50Ah 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.
Commercial Warranty
PowerBrick® 24V-50Ah offers a commercial warranty of 2 years, extendable to 5 years
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:
Technical characteristics of embedded BMS (especially charge and discharge power level)
Different IP (International Protection) level of product enclosure
Limitation on the number of battery that can be assembled in series and / or parallel
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® advanced lithium-ion technology will provide you with 3000 complete charge and discharge cycles at 80% DoD (Depth of Discharge). After 3000 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 5000 cycles.
Example 1: One PowerBrick® 12V-100Ah battery, after being discharged at 80% DoD for 3000 cycles, is now a 12v 80ah battery.
Example 2: One PowerBrick® 12V-100Ah, after being discharged at 65% DoD for 5000 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 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.
