4-Bank Battery Charger

1210-4

This MillerTech, 4-bank, marine Lithium battery charger was specifically designed for the avid fisherman who only settles for the very best! Our goal, when designing and developing this charger was to create a high-quality, feature-rich, marine battery charger that is reliable and simple to use, making your experience seamless and enjoyable! Our charger produces 40A continuous, meaning 10A is going into each of your 4 batteries at all times, (from start to finish) unlike conventional chargers that taper off halfway through the charge and take a long time to actually complete the cycle. What this means for you, is less charging time and more fishing time, which is really all that matters, correct?

Switched out the Minn Kota precision.
Works great. I feel like I get a better charge out of this than a standard marine charger.
