Lithium POWERBRICK + 24V 50AH battery

Possible discharge (up to 100%)

• The PowerBrick 24V-50Ah integrates in its case an innovative control system (BMS) to ensure a high level of security to use. The BMS control and constantly balance battery cells, in order to protect the battery and increase its service life. The BMS also protects the battery from rough treatment: deep discharge, charging voltage too high, etc.

• Very low self-discharge (< 3% per month)

• Since a PowerBrick battery+ Paut be discharged to 100% of its capacitya lead AGM battery can be replaced by PowerBrick+ with capacity 2 x lower than the lead-acid battery (ex: a PowerBrick)+ 50Ah replaces an AGM 100Ah battery).




Flexible system: up to 10 packs in parallel and in series 4

• Battery Lithium PowerBrick + 24V-50Ah has a nominal voltage of 25, 6V. It can be easily assembled in series (up to 4 battery in series) and in parallel (up to 10 batteries).

• Final Assembly voltage can be 24V and up to 96V (for 4 packs assembled in series), which meets the needs of almost all electrical applications of traction, solar or wind energy storage, servitude, robotics, trolleys, etc.

• Very low losses of Peukert (efficiency > 96%)

BMS (Battery Management System) built into the case: maximizes battery life and secures the battery

• The battery is protected by a waterproof ABS caseresistant to splashing water and dust)Degree of protection IP66).

• Technology Lithium iron Phosphate completely safe (no risk of explosion or self-ignition).

• Constant power during any discharge (low internal resistance)

• Excellent temperature resistance (-20 ° C to + 60 ° C)

Weight gain > 50% and size decreased by 40% compared with the lead-acid batteries

• The PowerBrick range+ has been designed to replace the lead-acid battery, offering a quadrupled energy density for a weight and size equivalent.

• To share its technology, the PowerBrick lithium battery+ 24V-50Ah can be installed in any position (vertical, lying on the side or upside down).

• The electrical parameters of the PowerBrick lithium battery+ 24V-50Ah are compatible in every way with those of a lead 12V AGM battery. In the majority of cases. the charging system can be kept identical and no complementary accessory is required to perform the replacement.

• Products PowerBrick+ are lightweight, compact, powerful and can be used for all types of uses and applications. The PowerBrick+ directly replace older generation batteries (batteries lead VRLA, AGM or OPZ) 24Vinefficient and harmful to the environment (use of heavy metals) and complexity of recycling.

• The PowerBrick range+ benefits of a 2-year commercial warranty.

• Life calendar > 10 years

• Low toxicity to the environment

• Certification: this, RoHS, a 38.3
