Lithium batteries

I posted somewhere here about an EarthX brand lithium battery I bought to replace a group 24 lead battery. Weighed about 5lbs, Saved about 35 lbs. seemed to be working great on street and at the strip. Fast fire up like never seen before. This past weekend as I was moving up in the staging lanes starting and cutting the engine I went to start up and nothing. Absolutely dead. I’ve yet to analyze the cause, but I think I f-d up my load calculations and alternator amps I needed, causing an overcharge situation. The fault indicator on these batteries will flash for various periods of time and then you can decipher what the problem is. Hopefully I didn’t F up my battery as it wasn’t cheap! You want the alternator at less than 50% iirc with all loads operating, to have alt amp reserve. Otherwise, I wouldn’t worry about exploding or fires. Do some research and ignore the comparisons to wheelchair, hand tools etc lithium batteries which is where the concern eminates from. Just do a better job figuring loads and what alternator and size lithium battery you need.

I was just thinking buy the time I add the weight of the cables and everything else to the back it's probably not worth the effort.I use a group 34 that if I remember right is about 46lb.I also use a gm style 100a alternator that's probably overkill.
I'll definitely need to do some research.Thanks for the info guys.
