I want to design a small project but my weakness or lack of knowledge is the battery/charging part.
My project is a remote controlled vehicle, its speed is not important, 1mph or less is ok, it will run on the grass.
Not sure if it will be enough power but will be starting with these https://www.banggood.com/search/1776804.html?from=nav (https://www.banggood.com/search/1776804.html?from=nav) and I will have an ISP32cam and another ISP32 board with a couple of servos for cam tilt and vehicle direction. I want to have the battery solar charged during the day and it will be running during the night time scaring skunks, groundhogs and bunnys off my property.
I've been spending a couple of days reading about batteries and it is a wild topic.
I looked at Lipo but too complex and dangerous, Lithium ion has not enough power, Lifepo4 is too expensive and I am down to SLA.
Just wondering if there is a better solution out there and should I go with 6V or 12V (based on motor selection, I am concerned about the weight)
Any suggestions would be welcome.

20V Dewalt power tool batteries. They charge fast are are made for repetitive charging and abuse. Find a higher voltage motor as higher voltage equals lower current. I use them for a lot of projects.

Thanks for the suggestion.
I don't know why I didn't think of this. Those are Lithium Ion. In my search, when looking at lithium ion, they all looked like small cell batteries that wouldn't provide enough power unless I pack a bunch raising the cost by a lot.
I don't have Dewalt but I do have Ryobi 18V 1300 mAhr and by experience with the power tools I have this would be more than enough I think. I will try to find higher capacity and lower voltage because hooking up a solar panel to recharge anything above 12 v would be too big (I think)
