100% brand new 5,6 or 7 cell Lithium ion batteries 20A (40A peak) protection PCB w/Balancing Description: This Lithium ion battery protection PCB protect single Lithium ion batteries. 20A continous current. Suitable for electric drills, motors, or aircraft models which require heavy current load.The default is 7 cells. User can modify it to use 6 cells or 5 cells very simply without any additional components. The PCB support Cell balancing features to prevent cell to cell variation. Balancing current is 80mA at 4.2V Lithium ion protection is necessary, as Lithium ion will explode when they are shorted circuit or overcharged, and damaged when they are over discharged. After Lithium ion is connected to the PCB, the board protect individual batteries from: 1. Over charging - Disconnect circuit when either battery is over 4.3V 2. Over discharging - Disconnect circuit when either battery is lower than 2.4V 3. Short curcuit protection - Disconnect when short circuit is detected Connection: Please see above connection diagram (For 7 cells) Procedure: 1. Connect your 7 cells in series (cells should be identical) (or for 14 cells: 2cells parallel, 7 cells in series) etc. 2. Then connect -ve of the cells to B-, then to B6, B5, B4, B3, B2, B1, B+ (B+ should be left opened for 6cells, B+ and B1 should be left open for 5cells) 3. Activate the circuit by charging to P+ and P- using Constant current/Constant voltage charger. Protection MOSFET: 4x100N03 By Default, 7 cells version will be dispatched. If you need 6 cells or 5 cells, please leave us a message. Or you can modify it yourself when you get the PCB, it can be done simply without additional components Important: 1. Please use identical lithium ion batteries when using this protection PCB 2. The PCB can be simply modify to suite 5 or 6 cells protection without additional components 3. The usage of this PCB requires knowledge on lithium ion batteries, Please DO NOT buy if you do not know what you are buying or do not know how to connect. Module Specifications
