100% brand new 13 cell Lithium ion batteries 20A (30A peak) 48V 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 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 4.35V 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 Procedure: 1. Connect your 14 cells in series (cells should be identical) (or for 28 cells: 2cells parallel, 14 cells in series) etc. 2. Then connect -ve of the cells to B-, then so on..... 3. Activate the circuit by charging to P+ and P- using Constant current/Constant voltage charger. Protection MOSFET: 4xAOT470 By Default, 14 cells version will be dispatched. If you need 13 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 13 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
