Yes it does. They are in a 16x AAA 4.8V pack each battery is 1.2V - I have been unable to find any but I did find a 4x AA pack that gives 4.8v ams 2500 mah that could work it would fit OK in the plastic container.
I now have small concerns regarding recharging but it appears in the original specific case a trickle charge is acceptable - So I’m hoping the same applies with the new packs.
So now I’m struggling to find something to fit in the box thats not prohibitively expensive.
Pete can you please verify that this looks like 4 x 4.8v in series for each 16 pack?
You need to be careful. Is there any sort of charging control circuitry in these things? NiMH cells are supposed to be charged at constant current (and generally NiMH require temperature sensing or -ve ΔV to detect the end of charge). Constant voltage charging is for Lead acid and Lithium ion batteries. Getting it wrong will at best result in shortening the life of the batteries, at worst a fire or explosion. They can be properly nasty if you get it wrong.
What about getting some battery holders yourself, nailing them to a plank, wiring them up and powering with that? It would mean you could control the charging yourself, by removing them and putting them into a decent charger.
