Is it safe to put a 12V sealed lead acid battery in series with a regulated linear powersupply to boost the output voltage ?
The battery is 12AH and can handle the power that I require, however I'm not sure if it will cause some kind of charging / heavy discharging - I don't use batterys much.
Alright then I'll bear that in mind, it was just for testing a stepper motor anyway.
Running it on 10V I got around 360 RPM max, but on around 23V I got over 1500RPM.
I should be able to get it running even faster with 30-40V.
I had an acceleration of 500RPM/s.
