At $285, I'd rather strap a $200 deep cycle/starter battery in the rear....with the added advantage of using it as an aux batt.
If you only have one battery in the 4wd and you ONLY use it for starting the 4wd, chances of a flat battery are very slim. If you travel remote and plan to use the battery for anything else except starting the 4wd, then you must have a backup.
If I had one of the mini booster things, as a
test, I would remove the normal battery ( as if the battery was dead flat ) and see if the booster starts it ( engine cold ).
