Hi, newbie to this place (but not to electronics - learned which end of a soldering-iron gets hot at the age of 8!).
I want to "repair" cordless-drill battery packs, so Sub-C NiMH rather than the 18650s that a lot of people seem to be doing, and this project looks great for this. I am very impressed with Frank's engineering and experimental approach. I wish I was as conscientious!

I see the kits are out of stock and I have signed up to be notified when the board-only kits are back in (I hope - haven't seen an acknowledgement).
Is there an ETA for the next batch of boards?
I'm on a tight budget (so the €100 capacitor kit is too much) and I'm not fond of mistreating Lithium batteries, but I have quite a selection of Sealed Lead Acid Batteries (SLAB) from my other hobby of Amateur Radio, but I haven't seen anyone mentioning this much, such as size of battery, using them in parallel, etc.
I have choices from about 7Ah to 80Ah (all 12V) but am mindful of how impressive shorting one of these can be! Would it make more sense to mount the 300A fuse directly onto a battery terminal in this case, and connect the cable from it to the "far" side of where it would usually be? That way a short anywhere, apart from directly across the battery terminals, would be protected.
Thoughts?
Cheers,
Howard
