Hello,
I have a question about charging the batteries for the first step of the bqEasy "5. Cycle" process. I am using a 2s1p cell with two 4.2V 4400mAh batteries.
1) Should I charge the batteries while connected to the bq20z65EVM while the Impedance track is "Initialized" (QEN is High)
2) How should I charge the batteries? Will the bq20z65EVM automatically cell balance at this stage? I see that my options are:
A) Connect 8.4V @ Charge Current to the 1N and 2P terminal to charge the batteries in series.
B) Connect 8.4V @ Charge Current to the Pack+ and Pack- Terminals and open the CHGFET. I believe that this will charge the batteries in series and not perform cell balancing.
C) Connect 4.2V @ Charge Current to the 1N and 1P terminal as well as another 4.2V @ Charge Current to the 1P and 2P terminals to charge the batteries individually.
D) It does not matter charge them however I would like.
Any help from an App Eng or anyone who has gone through this Cycle process with good results would be greatly appreciated.
