We want to assume that electronic circuit in Trik-L-Start will give the starting battery some protection in case of converter overcharging, but the selling brochure gives no details about it.

The only protection is that if the converter fails to produce high enough voltage the chassis battery will not be discharged into the parasitic draws of the house. House battery still goes dead.

Can't speak for protecting against converter failing at too high of voltage.

Wire does not provide this protection and you will be calling for a jump start. Also Trik-L-Start is automatic and never forgets. Wire is a manual process to connect and disconnect when appropriate. Be sure your wire is large enough to provide full current or has a fuse.

Your response applies only to part of my replay.
I will highlight again, that I was saying about "normal "on" position".
Sure straight wire brings more risk, but if you are talking about taking risk while spending money, why don't we consider taking a risk without putting a dollar?
Than with straight wire you don't have electronic board that will draw power from the batteries in case the charger is disconnected.
Most of users will never understand the differences between battery charger, battery insulator or battery combiner.
That is why salesman can mislead the customers without penalty.
