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?


  • It is extremely compact, with convenient mounting options that will make installation a breeze! Heavy Duty aluminum alloy body works great as a heat sync, plus creates a robust charger that is nearly indestructible.
  • No buttons to push, lights to diagnose, and no long user manual to ponder over. Simply mount it, connect it and use it!
  • This charger can also effectively charge your AGM or SLA batteries, (when charging these types, we recommend disconnecting the charger soon after the batteries become fully charged).
  • This charger can also be used in many different configurations!
    • Example: 1 battery = 4 positive leads and 4 negative leads, you will now be charging at 40A to 1 battery.
    • Example: 2 batteries = 1 lead set to each battery, remaining 2 lead sets are empty, now you are charging each battery at 10A Since each lead set is 100% isolated for all the others, this charger is truly versatile! If you at any time have questions about using this charger in your application, please contact us freely, we would be more than happy to discuss your needs with you and help you make the best decision. Your satisfaction is, and will always be our first priority!
