There are two versions of the K2 battery, one with (suffix EB) and

the technical literature, it sounds like the BMS is designed to
prevent battery damage in high discharge or high charge rate
situations. Since in a glider we're only discharging and charging at
about 2 amps max, can do without the BMS? Or have I got it wrong and
would be risking a fire?

I'd be inclined to get one with BMS, since there doesn't seem to be
anyway to equalize the battery cells without it; however, I can't find
any technical info on their site, so I'm just guessing. In fact, I can't
even find the one you are talking about on their site.

The lack of readily available info makes me bit leery about the product.
Any Li battery that is sold as a drop-in replacement for an SLA battery
should tell me a lot more about it than the price before I would put it
in my glider.
