Set of (3) USED 12V 120Ah Lithium Deep Cycle Marine Battery MML-12120b (w/ bluetooth)

We had a customer who had multiple warranty claims with these batteries and finally got fed up with them and switched brands. We made final warranty claims from our shop and they're sitting on the shelf ready for a new home. All of the warranty claims were based around the fact that the bluetooth would quit working because their app isn't as robust as other batteries. These batteries never actually didn't work on him, just the app. Heres the details - 1 is brand new from Monster. The other two were used in his boat for a few trips and were removed in working order with bluetooth app issues. We have mitigated those issues.  These batteries are still covered under warranty from Monster, we're just trying to salvage a little bit of the expense of customer satisfaction. We have been testing them in our shop for various uses and they are all still very functional.  Details on Battery Are you looking for a lightweight battery to power your 12V electronics or trolling motor?
