I bought a Hammant & Morgan Duo for £2 at a charity shop a few years ago. It gets occasional use with its 12 V DC auxilliary output connected in series with my Farnell L30-2 when I need around 42V when periodically cycling the three SLA batteries that power my electric bike to check their capacity. Charge using the H&M and L30, discharge using three 12V 21W bulbs in series. It is also used to control the speed of my 12V Expo Mini drill.
