I have an old cordless drill (and possibly some other tools) that have no batteries. I have a nice "36v" 24Ah LiFePO4 battery (voltage at full charge actually ~43.8V). What converter can I use to step that down to 18V for my drill? I'd especially like an adjustable-output converter with a display that shows output voltage so I can power other things with it.
So far everything I'm finding is rated for up to 40V (like this). Can I just use that? Will it be ok with an occasional input voltage above 40V? Or is there a better option that I just haven't found yet?
Thanks!
