从China供应商批发进口12v 4s Battery Bms Balancers Equalizers — FOB条款

This 12V 4S Battery BMS Balancer from Benbv Trade Co., Ltd. is an active cell balancing module designed to equalise the State of Charge (SoC) across four series-connected lithium battery cells. Unlike passive balancers that dissipate excess energy as heat, this active unit redistributes charge between cells during both charging and discharging cycles. This process can increase overall system run-time and improve charging efficiency.

The module is rated for 12V nominal systems and supports balancing currents that can range from 1A to 5A, depending on the specific configuration and cell chemistry. The housing is typically constructed from ABS plastic or aluminium for thermal management. It is engineered for integration into battery packs using lithium-ion (Li-ion), lithium iron phosphate (LiFePO4), and other rechargeable cell chemistries common in modern energy storage.

Primary buyers include OEM battery pack manufacturers for electric vehicles, solar energy storage systems, UPS (Uninterruptible Power Supply) units, and portable power stations. The product is also relevant for the replacement parts market. For sourcing, buyers should specify their exact cell chemistry, required balancing current, and any communication protocol needs (e.g., SMBus, CAN) when contacting the supplier to ensure compatibility with their battery management system architecture.
