从China供应商批发进口6s Battery Equalizer For Car Audio Batteries — FOB条款

This 6s active battery equalizer is designed for lithium-titanate (LTO) and lithium-polymer (LiPo) battery packs configured in six-cell series strings, commonly deployed in high-draw car audio systems and mobile power banks. The unit performs real-time cell voltage monitoring and active charge redistribution during both charge and discharge cycles, maintaining state-of-charge parity across all six cells to prevent premature capacity fade. Its PCB composite construction integrates MOSFET switching arrays, precision integrated circuits, and bulk capacitors to enable efficient charge transfer between cells rather than dissipating excess energy as heat. The compact form factor suits installation in constrained automotive enclosures where space and thermal management are critical.

Active balancing topology distinguishes this equalizer from passive resistor-based alternatives, offering measurably higher system run-time and improved charging efficiency. The redistribution of charge between cells during operation reduces overall charge loss and limits heat generation within the battery pack. Standard MOSFET-based active balancing circuits of this class typically achieve balancing currents in the range of 100-500mA per cell, though exact figures for this unit should be confirmed with the supplier. PCB material specification follows standard FR-4 or equivalent composite with appropriate copper weight for current carrying capacity. Component solder joints and trace routing must withstand automotive temperature cycling between -40°C and +85°C for reliable long-term operation.

Primary buyers include car audio installers, mobile power system integrators, and renewable energy distributors sourcing from Chinese manufacturers for global resale. The equalizer suits 24V nominal systems assembled from 2.3V LTO or 3.7V LiPo cells in 6s configuration. Applications extend to electric vehicle auxiliary power, marine battery banks, and off-grid storage systems where cell imbalance would otherwise reduce usable capacity. Buyers should confirm balancing current rating, quiescent power consumption, and communication protocol compatibility (if any) with their existing battery management architecture prior to purchase.

Benbv Trade Co., Ltd. is located in Changsha, Hunan Province, China, with a registered address at Building 8, Niulijiayuan in the 517000 postal zone. The supplier holds a harbor trust tier on the platform, which represents a baseline verification level. Notably, the supplier currently shows a 0.00% response rate with zero average response hours recorded, indicating that communication responsiveness has not yet been established through the platform's tracking systems. Buyers should factor this into their engagement strategy and consider direct outreach to assess current availability and support capacity.

The listing presents Benbv Trade Co., Ltd. as a source for QNBBM-branded 6s battery equalizer hardware targeting the car audio and mobile power repair markets. No manufacturing capacity, factory size, year of establishment, or revenue figures are stated in the profile, and none should be assumed. The supplier's product range appears focused on battery management accessories for lithium-based chemistries. Buyers are advised to request company registration documents, quality management certification status, and sample evaluation terms before committing to volume orders, given the limited response history visible on the platform.
