On board Lithium battery charger
Took some time to make room and mount it in my boat but it works perfectly and charges my lithium electronics battery quickly.

Just what I needed.
I needed an extra lithium battery and needed a 1 bank charger. From past experience I've found Miller Tech to be the best. The charger seems to be very well made I expect that it is going to live up to Miller Tech's standards.

Amazing
I replaced my two parallel 12V acid batteries, which powered my trolling motor and graphs. With those, I’d always notice performance degradation throughout the day. Not anymore with my MillerTech! I’ve used it during 5-hour tournaments, constantly running the trolling motor and graphs, and it held up flawlessly. No issues whatsoever. Worth every penny!

Compact Unit
Simple, easy to use, compact unit that’s 12v, 12amp dedicated lithium charger. That works!
