5.5A Smart Active Balancer with 5 mV precision. Compatible configurations: 3S4S packs for Lifepo4, Liion, and NCM cells; and 5S21S packs for Lifepo4, Liion, and LTO batteries. Active battery energy transfer equalization capacitor. Key benefits balancing efficiency and balanced energy transmission across all cells Continuous 24 hour balance with capacitive energy transfer No external power supply required; energy transfer occurs internally from the pack Low energy consumption and reduced heat generation Enhanced safety and long term protection of the battery Prolongs battery life and lowers maintenance costs What it is and how it works A capacitive energy transfer balancer that provides ongoing, allround balance for 24 hours Uses capacitive transfer technology to achieve balance without an external power source The entire balance of a battery string is achieved through internal energy transfer, resulting in very low losses Compatibility and configurations 3S4S configurations for Lifepo4, Liion, and NCM chemistries 5S21S configurations for Lifepo4, Liion, and LTO chemistries Suitable for use in battery packs that require active energy transfer balancing across multiple series cells Installation and safety notes This item requires soldering a few wires If you do not have relevant installation experience, have it soldered by a professional installer Before connecting the balance wires to the balance board, verify that all wiring connections are correct Ensure the bottom plate and battery connection terminals are insulated to prevent short circuits and burning Main features 5.5A smart active balancer balancing efficiency with low heat generation Energy transfer through capacitive means for continuous operation No external power supply needed Longterm battery protection and potential cost savings from reduced maintenance Use scenarios Home energy storage with Lifepo4 or Liion battery banks in 3S4S configurations, where consistent cell balance improves longevity and performance Offgrid solar or backup systems using larger Lifepo4, Liion, or LTO packs in 5S21S configurations, requiring reliable, continuous balancing without external power DIY electric vehicles, ebikes, or modular battery packs assembled from multiple seriesconnected cells, where compact, efficient balance management enhances safety and battery life
