Thanks for doing the research. I'm plugged in most of the time, except for a week or two here an there when I'm boondocking, so I think I'll just leave it for now.
StirCrazy, it’s not the couple of bucks, more that I read a few people that said it was worse for lithium batteries than just using the converter without it. Definitely a no-brainer if it really works appropriately.
ok so I did some digging into it and it doesn't seam to work that great unless your using battle born batteries as they call for a 14.7 charge voltage.
with others the issue seams to be that when you are applying 14.7V you might get lucky and have enough line loss in your system to drop it to 14.6V but if you don't then its very likely your BMS will shut the charging down as at 3.65V is where most over voltage protection is set at in a BMS so 4 cells that is 14.6V now the issue won't be while its charging but rather if the cells are not perfectly balanced then one cell might hit that 3.65V ceiling before the others and trigger the BMS over voltage protection.
for me, I would spend the extra money and put in a replacement converter, but if it isn't really a big deal to use it plugged in and you have enough solar to keep if fine....... I went two years with out using the converter in my truck camper, because I didn't know, or rather couldn't find the LI switch on the board and because early boards never had it I figured I had a early one. as it turns out they made two styles of Li capable board after the non Li ones and they have different ways to do it and I just found out about the second way and that's what I have, so now I can plug it in if I want.
so you don't need to run out and do the converter right away as the most it will do is under charge the battery, oh but turn off any equalization if you can. there seams to be more "new" converters trickling onto the market that might be worth waiting for, or or can go to a multitude of converter chargers that allow you to totally customize the voltages
