Lithium PowerBrick Battery 48V 105Ah


Battery PowerBrick+ 48V 105AhThe Lithium-Ion PowerBrick 48V-105Ah battery offers great security through the use of cylindrical cells in Lithium Ferro Phosphate (LiFePO4 or LFP) technology.

The PowerBrick 48V-105Ah incorporates an innovative control system (BMS) into its case to ensure a very high level of safety for use. The BMS constantly controls and balances battery cells to protect the battery and increase its lifespan. The BMS also protects the battery from mishandling: deep discharge, too high charge voltage, etc.

The PowerBrick range has been designed to replace Lead batteries, offering a quadruple energy density for equal weight and footprint.
Because of its technology, the PowerBrick 48V-105Ah lithium battery can be installed in any position (vertically, lying on the side or upside down).

The electrical parameters of the PowerBrick 48V-105Ah lithium battery are compatible in all respects with those of a 48V AGM lead battery. In the vast majority of cases, the charging system can be kept the same and no additional accessories are required to make the replacement.

Because a PowerBrick battery can be discharged at 100% of its capacity, an AGM lead battery can be replaced by PowerBrick with a 2x capacity less than the lead battery (e.g., a PowerBrick 50Ah replaces an AGM 100Ah battery).

The Lithium PowerBrick battery - 48V-105Ah has a rated voltage of 51.2V. It can be easily assembled in series (up to 4 battery in series) and in parallel (up to 15 batteries).

The voltage of the final assembly can be 48V and up to 192V (for 4 packs assembled in series), which meets the needs of almost all electrical applications of traction, solar or wind storage, easement, robotics, trolleys, etc.

The battery is protected by a waterproof ABS case, resistant to water projections and dust (IP65 Protection Index).

PowerBrick products are lightweight, compact, efficient and can be used for all types of uses and applications. The PowerBricktm directly replaces older-generation batteries (LEAD VRLA, AGM or OPZ batteries) in 48V, which are inefficient and harmful to the environment (heavy metal use and recycling complexity).

The PowerBrick range has a 2-year commercial warranty, extendable to 5 years

This (to) expensive battery with excellent properties was replaced by a different brand, Pylontech, offering the same capacity for the half price. The stackable Pylontech 19' rack Li batteries are comunicating very well with the WKS Evo 5 kVA 48V. It's important not to forget to set its front dipswitch position 1 to ON, if not you get the warning 61 followed by a shutdown. The cable connections between batteries and UPS are the most easy handling I ever saw. Excellent product, but not protected for liquids.
