Very nice work.
I take it you have a lathe.
Hope everyone is well.
I recently started going through all my torches to check their condition, remove all the batteries and charge those that required it (I haven't done this for far too long).
A few of the cheaper lights had suffered from some battery leakage. There was even some CR123 and Energizer Lithium AAA cell failures, which I didn't know was something that happened. Fortunately nothing expensive or irreplaceable has suffered, but I will now store all my non-active use lights completely empty, even the Li-ion ones, even if I haven't suffered a leak from them so far.
My Pila charger is still going strong, but my Cottonpickers variable current USB charger seems to have packed up in the years since it's last use. No charging light and no charging output, although it will read the battery voltage.
Can anyone recommend a Li-ion charger suitable for 10180 to 10440 sized cells?
Cheers.
