Agreed. Im not saying my suggestion below is a good solution. We shouldnt even be having this conversation, but here we are. This would solve the problem in the interim. A portable power station would allow you to recharge in the field. The Anker C1000 is on sale and works great. I have three of them and have never had any issues with them. Its portable and has so many other use cases. If you want something bigger look at the F2000 (I also have one of these) or newly released F3000. If you dont like Anker look at Bluetti or even Pecron. Jackery mostly uses lithion ion which you really dont want. Their newer units use Lithium Iron Phosphate so if you go Jackery make sure you get one that uses LiFoPO4 batteries.
I never had my unit get stuck in a field but I did have it drive itself so far under my truck I had to get a floor jack to get it unstuck.
