- Product descriptions: LVNOON 5.5A Smart Active Balancer 5mV Precision 3S-4S for Lifepo4 Lithium li-ion NCM Lithium/ 5S-21S for Lifepo4 Li-ion LTO Battery Active Battery Energy Transfer Equalization Capacitor
- Important note : This item needs to be soldered a few wires, please make sure you can do this job or solder it by a professional installer if you don’t have any relevant installation experience.
Before connecting the balance wire to the balance board, please check whether all the wiring connections are all connected properly, and the bottom plate and the battery connection terminals must be insulated to prevent short circuit and burning. - Main features: 5.5A smart active balancer; high balancing efficiency; balanced energy transmission, low energy consumption, less heat generation, high safety, and long-term protection of the battery, prolong battery lifespan, reduce maintenance fees, save money.
- This smart active balancer is a capacitive energy transfer balancer that can provide continuous all-round balance for 24 hours. Using capacitive transfer technology, no external power supply is required, and the whole group balance is achieved by internal energy transfer of the battery, with extremely low loss.
- Cascading Capability: equalizers support cascading, enabling users to expand their battery management system
- Free 30-Day Returns
- Full Refund for Damaged or Incorrect Items
- Guaranteed Delivery or Money Back
- Secure Checkout & Fast Support

LVNOON 5.5A Smart Active Balancer 5mV Precision 3S-4S for Lifepo4 Lithium li-ion NCM Lithium/ 5S-21S for NCM Li-on Lifepo4 LTO Lithium Battery
Working Voltage: 2.7V-4.2v, fit for NCM (Li-ion), lithium iron phosphate battery (LiFePO4/LFP).For Li-ion and Lifepo4 voltage is 2.7 V-4.2V, for LTO Voltage is 1.8 V-4.2V
The undervoltage hibernation voltage: 1.5-4.2V
Important Note:
1.This active balancer is not a BMS. It cannot achieve the functions of overcharge protection, over-discharge protection, and overcurrent protection when used alone, active balancer and the passive BMS are usually used together to ensure better improvement of the safety and performance of the battery pack.
2.Before connecting the balance wire to the balance board, please check whether all the wiring connections are all connected properly, and the bottom plate and the battery connection terminals must be insulated to prevent short circuit and burning.
3.This item needs to be soldered a few wires, so it is required to be installed by a professional installer if you don’t have any relevant installation experience.
Please select the right item number when buying! If you don’t know how to select, please contact us before buying.
Advantages:
1.Active balance, automatic start to work, avoid battery risk Prolong battery lifespan, reduce maintenance fees, save money
2.More efficient overall pack balance, ultra-low loss of energy transfer, low heat generation during balance, with under-sleep protection.
20Z copper thick PCB.
Balance current: 0.1-5.5A
Balance accuracy: 5mV.
Monitor the battery voltages all the time.
3.Join the effort to protect a greener earth with new sustainable energy.
4.Support balanced cascading for the battery packs like 24S, 36S, 48S etc.
5.Compatible with most of passive BMS on the market, easily upgrade your passive BMS to Active BMS.
Note for LTO battery:
The balance board default setting if for LFP lithium iron or NCM ternary lithium. If your battery is LTO lithium titanate, you need to jump welding the 1 and 2 to just to the LTO mode.
