So I got a second hand rx200 from my brother that he just wasn't using and he's the kind of person who gives things a pretty good unintentional durability test to, so, I want to make sure I'm not taking any unnecessary risks with this. It came with 3 purple efests in it which I understand are...kind of eh. I know he was using the mod to charge them which from what I understand is also kind of eh. Anyway I'll post a pic but one of the batteries looks like the wrap is not in the best condition so I probably won't use them anyways but opinions are welcome.
Now on to the battery marriage thing, and probably the only question I really need everyone's help on. I have 4 green Sammy 25rs that are about a week old that have all been used in my Istick pico that I just recently got, also about a week ago. I only have a 2 bay charger, nitecore um20. Can 3 batteries be married with a 2 bay charger and can I use 3 of the 25rs I already have? Thanks in advance!
