I've just measured my old battery and it seems that I can fit two of the toolstation batteries in the battery box, if I did this and connected them in parallel, would they still charge ok from the dynamo or is there something else I'll need to do? They are 6 volt 4a/h.
Kind of academic at the moment as they only have 1 in stock, but if it's a dead simple plug and play scenario I'll order a second one.
Cheers folks, and happy new yonk!
