Winter is setting in here in New Zealand, so the ride on mower will be parked up until spring kicks the grass back into action. This normally requires remembering to throw the battery charger on for a bit, and more importantly, remembering to take it off again. There are maintenance 'Automatic' chargers available at prices ranging from not bad to 'I just want a charger, not the whole manufacturing plant' 😳. But what's the fun in buying one when there is a shed full of crap the bits can be extracted from. So I borrowed most of the design of a Ducati switching regulator, and improved the control side to something a little less privative, and lot more reliable.



Works a treat.
Cheers

This is way better then my chalk board reminder to cycle the various batteries for all our power tools every month or so

  Exactly, the only time to throw anything out (scrap) is when it's good for nothing else.
