CMB (Charging Manage Board) for 14.8V Li-Ion (10.0A limited) Battery Pack

Features:

Manufacturer part# CMB-S4A3
The board is capable of being charged by a 18-25Vdc 2.9A adapter and discharged at the same time
- Charging terminal will cut off @ 16.8V when fully charged. If the discharge terminal was being continuously discharged (at less than or equal to adapter's output current) until 12.3 +/- 0.25V, the charging terminal will reset and start charging automatically. (Please wait 5 min for LED 1 Flashing to change to RED to indicate charging)
- If the discharge current exceeds the charging current while charging, the battery will continue to discharge until 10.6 +/ 0.25V cut - off voltage and the charge terminal will NOT be reset to start auto charge (must disconnect & reconnect the charge terminal or ac power to adapter to start charging)!
4 cells Li-Ion battery pack ( Li-Co or LiMnNiO ) protection with 2.9A Max charging rate & 10.0A Max discharging rate
Input power: DC 18V - 25V ( > 60W) from charging terminal (Input Terminal)
Output Terminal: P+, P- Soldering Spot
Input Terminal : 5.5mm x 2.1mm female barrel socket
- Need 5.5mm x 2.1mm male barrel plug for DIY? Please click here to order separately
- Must connect with correct AWG wire based on American Wire Gauge table ) (Please click here to view)
Max. Charging rate: 2.9A
Max. Discharging rate: 10.0A
Fuel Gauge: 5 LEDs built in the board to show battery charging/discharging status
- Type: Voltage based
- LED 1 indicate battery charging status
  - LED 1 = Flashing = Reset Charging circuit (about 5 minutes)
  - LED 1 = Red = Charging
  - LED 1 = Off = Fully charge
- LED 2 - LED5 indicate battery discharge status
  - LED 2-LED5 status (Note: only use for indication, does not give accurate indication)
    - LED 2 = Red = 25%
    - LED 2 & LED 3 = Red = 50%
    - LED 2 & LED 3 & LED 4 = Red = 75%
    - LED 2 & LED 3 & LED 4 & LED 5 = Red = 100%
- Included Fuel gauge on/off switch to check the status of charge/discharge
