Battery jump packs what I learned the hard way
They apparently need to see some minimal voltage as a safety item to check correct polarity. Mine didn’t have an override for a really dead RV battery,so it wouldn’t release voltage to jump the RV batteries. Others have a manual safety override for really low batteries. About the same $ like $90-$100
From Amazon
Jumtop=no $91
Novo=yes $99
