I just noticed M2 Power in the ads section below. They list a very convenietly sized 4 cell 40AH unit with BMS. Has any one enquired as to the price of this or any of their other size options. I am curious, but not likely to buy, so I would rather hope that the forum can provide the answer rather than wasting the companies time to answer me.

Also if I were to buy 6 40Ah units would I need an additional battery rather than cell level balancing system to keep my 6 12.8V units in synch.?

Yes I know many don't believe in BMS anyway, but I wouldn't want to spoil the ship for a ha'peth of tar.

If you think the cells wired in series need a BMS then batteries wired in series would need the same.

Why would these need a BMS? It looks like they have some sort of power control module built in for cell balance, cell level HVC LVC pack level HVC LVC, and over rate protection.

Yeah, you're right, don't know what I was thinking

Yes I was intrigued by them because they look like a floodie sized unit at a fraction of the weight with cell level management built in, but does anyone have any idea of the price?
As I said above it seems a little unfair to pose as a potential buyer when , sadly, I am not in a position to replace my floodies. They remind me of LifeBat which are VERY expensive.

Looked around for pricing and didn't find anything, but I can almost guarantee it's expensive.
