The are brand new lithium packs set up for Gem cars . They consist of 2 , 10s modules (20s total) . 180ah capacity . These will significantly increase your range and your performance . A set of these with a 5hp stock motor will outperform a stock Gem with lead batteries and a 7.5hp motor . With 10.35 gears and larger tires we had a stock gem hit 40mph .
You will need to have your charger updated to charge lithium($75) and to hook a BMS ( $140 -200).
These are compatible with 2002 to 2015 Gems . 2016 + packs are also available .
The modules weigh 70lbs each which is significantly lighter than the 400lb lead battery pack .
The modules will be have attachment points added to each cell to enable easy BMS attachment and the cells will all be numbered for easy identification .
The modules are new but are scratch and dent . The plastic side covers can be cracked and the stainless tops can have scratches . None of this effects performance or durability .
22s and 24s high voltage extreme setups are also available .
Do you have any recommendations on a DIY kit or enough detail to be able to make it happen. The gels we had I think were mostly damaged due to the fact it gets over 100 here. That was when the posts melted and then it was down hill from there. I need to be sure what I used can handle the higher heats too.
DIY low cost high mile battery. 74v 180ah battery, $1000. 2 37v modules for shipping. Battery only.
2 x 10s configuration uses any 72v charger.
Experience or good skills required.

Google says: The melting point of lead—621.5 °F.
I hope you don’t think the outside temp had anything to do with your battery post melting down. Unless you are on Venus or something, In which → shipping a battery is going to cause a problem. Does anyone have Elon’s number?
My neighbor works for the FEMA, Mr Musk sends out lots of late night emails, some useful, some not. Everything from pep talks to retire early and get an extra 8 months severance pay. The number for Elon Musk in the .sig on these emails is (248) 434-5508
LOL… not entirely, there was also a loose connection and it was that plus the extreme heat when things happened. I meant the extreme heat not just the temperature outside. Definitely didn’t type it correctly.
