Heltec 6S/7S/8S Active Equalizer Balancer (5A/6A) for LiFePO4, Lithium, Lipo, and LTO Batteries with Capacitive Energy Transfer

Features:

• Type: Active equalizer designed for 6S, 7S, and 8S battery packs, supporting LiFePO4, Lithium-ion (Li-ion), Lithium Polymer (Lipo), and Lithium Titanate (LTO) chemistries.
• High-Efficiency Balancing: Capacitive energy transfer technology allows for efficient redistribution of charge across all cells, improving battery performance and longevity.
• Precision Balancing: Supports whole-group equalization (not limited to adjacent cells) with voltage accuracy within 5mV.
• Adjustable Balancing Current: Dynamic current ranges from 0-6A based on cell voltage differences, ensuring effective equalization even in large battery packs.
• Low Quiescent Current: Consumes minimal power when idle (approx. 12mA), with a dormant power-off mode drawing less than 0.1mA to conserve battery life.

Specifications:

• Brand: Heltec
• Supported Battery Types: Li-ion, LiFePO4, Lipo, LTO
• Battery Configuration: 6S, 7S, and 8S (supports packs with 6, 7, or 8 cells)
• Working Voltage Range: 1.8V - 4.5V (suitable for various battery chemistries)

Working Principle:

The equalizer uses a capacitive fit transfer method to balance the charge across all cells in the battery pack. When connected, the balancer begins transferring excess energy from cells with higher voltage to those with lower voltage, optimizing overall battery pack performance. The capacitive energy transfer method ensures minimal energy loss, making it ideal for applications requiring high efficiency and longevity.

Applications:

• Electric Vehicles (EVs)
• Solar Energy Storage Systems
• Powerwalls and Off-Grid Systems
• Electric Bicycles and Scooters
• RC Models and Drones
• High-Capacity Battery Packs for DIY Projects

Benefits:

• Extends battery life by maintaining cell voltage balance.
• Improves charging efficiency and reduces heat generation.
• Ideal for balancing large battery packs used in EVs, solar storage, and high-drain applications.
