Hi guys, I have a PH-40 that I bought about 4 years ago. Anyway, the battery seems to be slowly dying now and I found some other people on CPF saying that it is not too hard to open up and replace the 8x18650 li-ions inside. But I've so far been unable to find any photos or instructions describing how to actually do this. So anyone done it? Is it actually feasible? Will the charging/discharging protection still function normally if the old cells were replaced with higher capacity cells?
Thanks in advance!
