About this item
- 【NOTE】Before connect the cable terminal to the balance board, be sure to check whether the battery pack is connected correctly and insulate the bottom of the balance board. When you encounter problems, please contact us to solve the problem, rather than direct refund/return. (For the latest application, please search "enerkey" in the app-store to update. Turn on the phone location. If phone can't find the machine, close the APP background, restart the APP and try again.)
- Applicable battery type: NCM/LFP/LTO (Li-ion/LiFePO4/LTO); Single-cell working voltage: 1.0～4.5V; Applicable battery string number: 10S-24S. But (No external power supply)The minimum total voltage of the battery pack is greater than 30V, the recommended value: Li-ion battery≥ 10S, LiFePO4 battery≥ 12S, LTO battery ≥20S; If the battery pack total voltage is lower than 30V, External 30V-100V DC power supply is required(eg. 4S-8S). The combination of multiple equalizer boards supports cascading into a battery pack equalizer board with a higher number of strings.
- Balance method: Patented balanced architecture Flying super capacitor method, combined with point-to-point energy transfer algorithm for high-efficiency balance. Balance current: APP-custom setting: 1-4A, due to the use of constant current and constant voltage technology, the balance current has nothing to do with the battery voltage difference; Voltage balance accuracy: ±1mv (voltage measurement accuracy), ±1mv (voltage equalization accuracy), this product is calibrated by Keithley DMM7510.
- Under voltage protection sleep voltage: Under-voltage sleep voltage can be customized by APP: 1.5-4.2V; Drop detection: Support; Static working current: Balance off 10mA, balance on 25mA; Board Size: 5.51x5.0x0.87inch; Balance wire length: 15.7inch; 【Tips】App-Name: for iOS system, please search-GeeWEBMS, for Android system, please see the photo or contact us by message, we can send you download link, wiring method and english manual.
- 3-LED indicator: Blue is the BT status indicator: always on, the link is successful, Flashing, link down; Red is the fault status indicator: always on, internal fault, Flashing, battery test failed; Green is the working status indicator: always on, the balance is completed Flashing, balanced work; 【Note that】The time required for equalization mainly depends on the battery capacity. It is normal for the capacitor to heat up during energy conversion.

ackage Includes: 1x 8-24S Smart Balancer Board, 1x 14pin 18awg Cable, 1x 12pin 18awg Cable
NOTE : This active balancer is not a BMS protection board, so no matter how bad the battery you use to test, it can be used, But it has no functions such as over-voltage, under-voltage, or over-current. A BMS is required to manage all those things. Suggest use it in parallel with the BMS protection board.
Specification:
Applicable number of strings: 8S-24S
Applicable battery type: NCM/LFP/LTO (Li-ion/LiFePO4/lithium titanate) fully compatible
Applicable (NO need external power supply): The minimum total voltage of the battery pack is greater than 30V, the recommended value: ternary battery ≥ 10 strings, iron-lithium batteries ≥ 12 strings, LTO batteries ≥ 20 strings
Compatible: If the battery pack total voltage is lower than 30V, External 30V-100V DC power supply is required(eg. 4S-8S). Of course, The combination of multiple equalizer boards supports cascading into a battery pack equalizer board with a higher number of strings.
Single voltage working range: 1.0-4.5V
Voltage equalization accuracy: ±1mv (voltage measurement accuracy), ±1mv (voltage equalization accuracy), this product is calibrated by for Keithley DMM7510
Equalization method: Equalization structure flying capacitor method, combined with point-to-point energy transfer algorithm for high-efficiency equalization.
Balance current: APP-custom setting: 1-4A, due to the use of constant current and constant voltage technology, the balance current has nothing to do with the battery voltage difference.
Drop detection: Support
Under-voltage protection sleep voltage: Under-voltage sleep voltage can be customized by APP: 1.5-4.2V
Quiescent operating current: 10mA for balance off, 25mA for balance on
External power supply: No external power supply is required, and the entire group is balanced by relying on the internal energy transfer of the battery
Board size: 5.51x5.0x0.87inch(LxWxT)
Working environment temperature: -20℃ to +55℃
3-LED indicator:
Blue BT status indicator: always on, the Bluetooth link is successful; flashing, the Bluetooth link is disconnected.
Red fault status indicator: always on, internal fault; flashing battery test failed.
Green working status indicator: always on, balance is completed; flashing and balance is working.
