Well probably what you want is a 12V jump pack. I know others may disagree but I'm partial to an old-school lead acid one. They can still be had with the reverse polarity protection, but none that I've ever seen have that annoying issue of an automatic timeout that shuts it off right when you might need the boost to jump the car (like what was seen in Kyle's YouTube video with his leaf). Plus they can deliver way more amps so even if you need to start a friend or stranger's gas car or truck, you'll have no problem.
I believe this will work for you. It's a 12V LiFePO4 battery with a built-in Battery Management System [BMS]. The original battery is also rated at 50AH. I believe the BMS would allow you to direct substitute it for your factory battery.
I'm going to replace the stock 35Ah AGM with this one, has the battery terminals on the same end like the original just add adapters as shown, and is almost identical in dimensions.I believe this will work for you.

I probably would use it all the time, but to get you out of a pickle, it should work great. The good thing about LiFePO4 is you can charge them and they stay charge for a very long time.... and they are small and light. So charge it and store it in the Frunk.
You'll have to add adequate jumpers to connect the battery to your existing disconnected cables, but that's easy. Be sure to isolate the ends of your jumpers to keep them from touching.
What does the rest of the group think? Do you think it will work? Why wouldn't it?
The bms of the lightning is expecting the charge profile of an agm battery and afaik you can’t change it to lithium. There are options by a company I think it’s called omhu that has a lithium battery that has circuitry on it that spoofs it as an agm battery to the truck when it wants a charge but it’s pretty expensive and looks like poor build quality. It’s discussed on some forums maybe this one tooI'm going to replace the stock 35Ah AGM with this one, has the battery terminals on the same end like the original just add adapters as shown, and is almost identical in dimensions.
The only caveat to using these type of batteries is temperature, LFP does not like it cold, extreme cold that is, will charge and discharge well below the temps I see down here. They also make them with built in heaters for extreme climates.
I have a solar system for powering my home and I use this brand exclusively. Customer service is top notch! Only had to contact them for a couple of issues which they promptly remedied with other products they make, haven't had any issues with their batteries.
The voltages are near identical, it won't make any difference. I've already proven this with the battery array for my home solar system.
I purchased this one, it also has a tire inflater, worked well so far.
The only difference since you seem to want an argument, is the discharge curve, the LFP is pretty flat from start to finish, the SLA aka AGM has a constant drop from start to finish. If anything, It'll keep the main HVB from having to charge it as often.
I'm explaining, you're arguing, and no longer with me. I have extensive experience in electrical/electronics. I know what I'm talking about. Go right ahead and listen to the marketing fodder and drain your wallet if you like, makes no difference to me.
