PowerMax AC to DC Converter Charger With Battle Born Batteries

The Powermax PM3 AC to DC Converter/Charger is a fantastic converter/charger that works tremendously well with Battle Born 100Ah 12V LiFePO4 batteries! The most prominent feature of this charger is the ability to manually adjust the charging voltage. This is huge for LiFePO4 batteries because it enables the user to charge their LiFePO4 batteries to the ideal 14.4 V and get the most life and power out of their battery!

“Here at Common S.W.A.G Bowfishing, we made the switch to PowerMax Converters last year and we haven’t looked back! We installed the 24 volt converter on our  20 ft tournament and guide boat and it works great. We can power our 24 volt Minnkota Riptide all night at 100% power and never have to worry about coming off the water when the fishing heats up! Get yours today! You’ll be glad you did!” See the video at https://www.youtube.com/watch?v=kj_DRyd3ThE
