  On 10/21/24 I purchased two 36v lithium trolling batteries and a combined 12v/36v onboard charger. I have not had one problem after one year of use. I use these batteries for my Minn Kota 36v Terrova, 87" shaft, 112 lbs of thrust trolling motor which is on my 2021 232CC Tidewater. These batteries hold my boat in position for 4+ hours in currents over 2.5 mph and with wind up to 12 mph. And I still have 85-90% charge left! Worth every penny. My old Optima batteries would not last that long, I'm so happy I made the upgrade when the one of the Optima batteries were at the end of their life. When the two starting batteries need to be replaced (which will be next spring) I will be upgrading to lithium and adding a separate battery for the electronics. I only wish I purchased the 12v to 36v on the run charger over the combined charger. Thank you Monster Marine. I'm sorry I waited one year to write this review but I wanted to put them to work and make sure they held up, which they certainly did.

  There on board 36v charger that charges on the go has been the BEST investment for the money on my lithium battery setup

  Best batteries and chargers you can get in your boat. I finally never worry about my batteries before a tournament. Love the fact I can open the app on my phone and see the level of charge from inside my house.

  If you’re in the market for a lithium battery this is the place to go. I had a problem with a battery I ordered not charging. I sent a email to the company and in no time someone had responded with some solutions. We tried multiple things with no success. Once troubleshooting was over they sent me a new battery and haven’t had a problem since.

  I bought a 36v charger for a Bioenno battery. I am not sure if it was compatible because the battery never worked after I plugged one charging. Seemed like a well built product though. I reached out to MML and they said it wasn't the charger. Bioenno sent me a new battery.
