- 6S to 8S Compatibility: Designed for 6-cell, 7-cell, and 8-cell NCM, LFP, or LTO battery packs.
- Up to 5.5A Balancing Current: Provides approximately 1A at a 0.08V cell difference for fast, efficient voltage balancing.
- Whole-Pack Active Balancing: Redistributes energy from higher-voltage cells to lower-voltage cells across the entire pack simultaneously.
- Typical 5mV Accuracy: Helps reduce voltage differences between cells for improved battery performance and longer pack life
- No External Power Required: Operates directly from the battery pack with an 8mA static working current.
Heltec BMS 6S-8S 5.5A Active Balancer Equalizer NCM LFP LTO 0877A
This Listing Includes:
- (1) Heltec BMS 0877A 6S-8S Active Balancer Equalizer
Improve battery pack performance and help extend cell life with the Heltec BMS 0877A Active Balancer. Designed for 6S, 7S, and 8S battery packs, this module transfers energy from higher-voltage cells to lower-voltage cells, helping the entire pack maintain a more consistent charge level.
Unlike passive balancers that release excess energy as heat, this active equalizer redistributes energy within the battery pack. The complete group participates in balancing simultaneously for faster and more efficient voltage correction during charging and discharging.
No external power supply is required. The balancer operates using energy from the connected battery pack and supports NCM, LFP, and LTO battery chemistries within their specified voltage ranges.
Features:
- 6S to 8S Battery Compatibility: Designed for 6-cell, 7-cell, and 8-cell series battery packs using NCM, LFP, or LTO cells.
- Up to 5.5A Balancing Current: Delivers approximately 1A of balancing current at a 0.08V cell difference, with a maximum allowable current of 5.5A.
- Whole-Pack Active Balancing: Transfers energy between cells across the complete battery pack simultaneously for faster and more consistent equalization.
- Typical 5mV Balancing Accuracy: Helps reduce cell voltage differences and maintain more uniform performance throughout the battery pack.
- Self-Powered Operation: Requires no separate external power supply and uses energy from within the connected battery pack.
