[RE-wrenches] 48v small controllers

[R Ray Walters]

The nice folks at  BZ Products have made me small custom voltage controllers before, for just that application.
Prices, as I recall were less than a C40, and much smaller footprint/ weight, which is an issue on a mobile application.

It is made for bass boats and allows them to use the 12 volt alternator to charge the 24, 36, or 48 volt trolling motor batteries when the big motor is running. It will likely want to see 12 volt nominal input which limits your module choice somewhat. It is a sealed unit and has a 40 amp max rating. Not sure if they have a website but I have a phone number for them. Contact me off list if you need it.
