Interesting problem here and one of the problems immediately inherent is no system specs have been published so it is hard to know exactly what is being discussed. After spending some time researching Ecotek it seems the Ecotek is likely a 12 volt system but again I don't know as it has not been published. 2 Modules ( aka a battery which has a rebranded "marketing" name I also suspect ) equals how many amp hours or watt hours? Maybe 400 Amp hours? Maybe 800 Amp hours? Not sure. The batteries or modules should be clearly designated if you inspect them. We really need system electrical specs ( not some companies rebranded for profit jargon) to have a meaningful discussion. Having said that there are a few things I do have an opinion on from looking at other bits of information gleaned from a some amount of research. I believe your Roadtrek likely has a second alternator for recharge purposes and I believe that alternator is a 12 V alternator so lets start there. This assumption indicates you need 12 V batteries so that you don't have to replace other bits and bobs of equipment making it more expensive. Next thing, I read a 2018 document that said there is a 6 year warranty on Ecotek. Could you still have warranty perhaps? Then I wonder about temperature shut off. Lithium batteries ( the good ones.... not all of them ) have high and low temp cut offs in the BMS. Perhaps your batteries reached a high temp alert given the time of year you are posting? Maybe the BMS have just not reset? Could be as simple as that. I don't know how serviceable these Ecotek "modules" are I have never seen one. Are they a metal case or plastic glued I am not sure. So if I was you I would walk away from your RV tech. Number one, he has failed to learn all of the information developed in the last 10 to 15 years and wants to drag you down a road back to the 90s at his profit and your expense. I would not want the extra space and weight of a battery bank I can only use 50% of the amp hours of good for several hundred cycles. Not when I can use 80 to 90 % percent of a lithium bank good for 4000 cycles and STILL have 80 percent capacity. Much cheaper long term. And charge much quicker and more efficiently. Oh, and to change to AGM you will have to change the charging profiles of your chargers lest you burn out the AGMs did your tech tell you that? Hope that he did and knows how to make those electrical adjustments. This is pretty basic stuff to understand so anyone who doesn't get that probably I would walk/run away from. Next I would find a battery shop that sells nothing but batteries and knows lithium and take the van over there and have your batteries ( modules? why do we need to complicate things) removed from the van and tested by a professional and if they come up bad ask why and about how much to install a new BMS. You need to determine if it is the cells or the BMS that is bad or maybe an internal connection. Proceed from there depending if your batteries are serviceable or not. If not I feel for you. You should not have to use the same BMS as what is OEM but if you do change you change them in each battery. You determine the BMS by what cells you have and what features you want. A good battery shop/distributor will know this.
This fellow on Youtube is the real deal and he doesn't sugar coat things I like him. Spend some time on his channel and educate yourself a bit. He has been extremely successful telling the truth and how refreshing is that these days!
I think the SOK is a very good serviceable battery so I chose this particular video and it has a link to a distributor and price should you choose to use it. You could go with Battleborns at twice the money but it is not necessary. In this video he also talks about cell quality and the differences. I don't know what "Ecotek" uses. Who owns Ecotek anyway? Anyone know? And now you have a price point in your back pocket before you enter the battery shop and an idea of how to proceed. Will also has a forum for Lithium/Solar with lots of good resources so that is where i would go ask for a battery shop. Empower yourself and have the correct specifications at the ready. I am in no way affiliated or associated with this video channel. This is simply a resource for everyone here to use and educate themselves with.
