So i purchased the Posentic Atom 2 fly more pack and it charges 3 batteries together. I am thinking of getting a large power bank with 4 usb c charging ports, my question is can i charge the batteries while the are in the parallel charging block NOT via the block itself but using the usb c port on each battery while the batteries are in the block… not sure if I’m making sense, and not sure anyone will know but worth a shot lol
Funny, I tried this last week, just the one battery that I had used, it was about 70%.
I used my 20,000 mah power bank no problem at all.
I don’t think it would be a problem charging all batteries this way.
I hope this is what you mean 
Forgot to mention mines is the atom 3 axis.

Yes I think that’s it, did you do it while it was in the charging pack? or separately?
The battery was out of the charger, I’ve just plugged the the power bank into the battery which is now in the smart charger and it appears to be charging, )red light is on)
I’ll let you know if anything changes! 
@Donjack1964 ok great, thanks for the info
