I haven't seen a 100AH AGM this cheap in years. Nice score on a very versatile battery.

I readily admitted my oversight. Is attempting to humiliate good people on the internet (people who are saving you money, I might add) some kind of sick hobby of yours? This thread is a stellar deal and I stand by that. If all you can bring is negativity, please bring it elsewhere.

You don't have to take it personally, people are just discussing prices. Thanks for posting this deal.

I'm typically using LIPO4 for off grid or inverter applications. What are folks finding this to be a good deal for? What use cases? I have a 600w inverter / 25 AMP charger device I'm trying to decide if a couple of these batteries would be a good pair with. AGM batteries tho you don't want to discharge below 50% roughly. If you're buying more than one or two can you share what for? Just trying to decide if I want to go for this deal or wait for some Lipo4 batteries. Thanks!

AGM doesn't release H2 and toxic gasses if it catches fire. Lithium Iron Phosphate does in the chance that it does go into thermal runaway.

People will chime in saying LiPO4 is safe blah blah blah. It's safe until it isn't.

So in that case, with the best performance not dipping below 50%, what are you using it for? Off grid setup? Golf Cart?

I planned on using them in a 36V golf cart that gets limited use. I did end up canceling since they had been cheaper recently and I would have to figure out a decent charger for them.
