"2.) We highly recommend the purchase of good quality ,12 volt deep-cycle marine/RV batteries ranging from group 24 to group31, which is our preference............ Regular auto batteries and other batteries not designed for deep cycle discharging and recharging will have a shorter life span if drawn too low too many times. ...."
"4. I've got two 12 volt batteries under the hood of my vehicle. Can I hook up the Ready-Welder II to these batteries with the motor running and batteries cable still connected? Answer: No. The batteries are normally wired in parallel for these applications (assuming your vehicle operates ion 12 volt) and the RWI-II normally uses 24 volt for welding and requires these batteries to be wired in series. Be sure to read the operating instructions page for some exception to the 24 volt rule! Leaving the batteries connected to the vehicles electrical system while the RW-II may cause severe damage to the vehicles electrical system. Don't do it!..."
In the context of over landing you would need to bring 2 x 12v deep cycle batteries for welding applications which IMO is too much extra weight in a these trips.
You are correct about my wrong use of the term "voltage" discharge, it is the current discharge that I meant to refer to. Point taken the the current discharge is not probably not as "massive" as I stated. Thanks for correcting me - I'm here to learn too.
