No offense, but that isn't really a knock on the battery or the brand. A 12.8V 33Ah LFP battery has 422.4 Watt hours of power in the perfect world. The Garmin 106 will draw about 3A continuously or about 40W. So that is right about 10 hours in real world conditions. Anyone have any experience with the company itself? Not their resellers but the manufacturer, MillerTech. I think they are out of Ohio.

OK, just wanted to report back. I talked to Jason at LDSreliance. He dang near answered on the first ring, which shocked me. Turns out he also has a Youtube channel and is somewhat of a battery and solar expert or something. Anyways, he was nice enough to talk to me for about 45 minutes about my boat and needs and issues. He even looked up the specs of my Lowrance Elite to make sure I will have enough juice for it as well as the trolling motor. He also sells some other batteries that have Bluetooth that I am considering, but I digress. I can't vouch for the batteries but the dude was helpful and knowledgeable and I didn't have to wait until 3am for an email from China with a bad English translation. I'll never buy something like this from Amazon again. Thanks for the help all! I'd still love to hear from anyone that actually has or knows someone that has these MillerTech batteries if there is anyone on this board that sees this. I did a search but didn't turn anything up.

Thanks, I agree with everything on there excepting the cell grading. That is a big deal for me. I will call them and see what they have to say. Thanks!

Long time lurker, first time poster. I'm fairly new to the sport but I've heard enough about lead acid batteries to know that I don't want to be out on the water depending on them to get me through the day powering a fish finder and trolling motor. I've heard good things about MillerTech batteries from some friends. Anyone have these and can weigh in? From what I have seen on some other forums, they are true Grade A lithium batteries made in Amish country. I don't want the fake junk from Amazon. I've also looked at a few other brands but keep coming back to these. Thanks in advance.
