Hey all-
So I have a very strange issue I need help with. It has to do with connecting 2 of these in parallel:
https://www.ebay.com/itm/10pcs-LiPol...53.m1438.l2649
They have a protection board for each of them, the DW01-P (attached).
I am using this to power a small audio / video device that consumes < 2A from the both of them (total). There was a lot of background noise / audio rippley distortion crap that went away only when I plugged in the USB charger (!)... OR, I found out, when I only have one battery connected. They are fighting each other in parallel (even though they balanced out a long time ago).
I think the li-ion PCBs are confusing each other and going into over discharge protect (ODP) mode and then back on ever few milliseconds. It's weird and I've never seen this before.
Any ideas on what I could do? Some kind of filter or balancer IC would be great.
