Hi Wats!
I've been making new battery packs for my model gliders this morning. The old batteries wouldn't reliably hold charge. I didn't have any cells the correct size so I've made 3-cell instead of 4-cell batteries that will fit in the space available, and fitted some tiny voltage step-up converters to give the same volts from 3 cells as I used to get from 4.
Off to Wales tomorrow for a few days of model gliding.
