Re: Do I have to be concern about..........
As posted , if u have a genset on the 5er ,, yes use it ,, if u have an inverter it should do a short shot on u'r micro wave ,, but that depends on the wattage of the micro and the amount of usable batt power u have ,,, they may be old and not be up to full power ,, or u may have a shorted cell in one and would never know it....
Here is what i would do ,,,, when u get settled in at u'r camp sight ,, with shore power ,,, don't plug into shore ,,, and try to run the micro off the inverter ,, and see how it works ,,, if it kills the batts then plug into shore power to charge the batts and then get the batts tested,,,
Jmo ,, but i have seen this work
