I have some 9.6V NiMH battery packs (originally for R/C use).
Taking apart the plastic casing, I found eight AA-sized unmarked batteries connected in series.
Since my current project needs 12V, the simplest thing would be for me to desolder the tabs and assemble a set of ten.
But I've always heard that batteries and soldering irons don't mix.
If I'm to use these at all, it will require a certain amount of soldering and/or desoldering (cutting a tab joining two batteries doesn't leave enough of a stub to solder onto). (I can't cut them apart and put them into a battery holder because of the added weight.)
Is the danger of soldering/desoldering batteries only that it might ruin them (an acceptable risk), or could a NiMH cell explode/be dangerous?
Alternately, is there way to change from 9.6VDC to 12VDC,
