Hi guys/gals, we’ve purchased a new 4005 voltage and can’t keep batteries to hold a charge.
This last trip out I dropped the gear and ran out of power to even unhook or start gen.
Ran to town and bought 2 6v golf cart batteries. Plenty of reserve power now but do I dare plug the camper in and forget it until we pull out again? Will the chargers in the newer trailers stop when the battery’s are charged?
Tried for two day to get an answer from keystone and kept getting transferred because no one seemed to know how the charging system works.
Thanks in advance,Andy

Do you own a digital volt meter? You're going to need one.
Hook up the batteries, plug in the shore cord and measure the voltage on the battery terminals. It should be around 14v if it's charging.

It is charging at 14.1, I’m wondering if it will stop charging when batteries are at full capacity like a battery tender does.

14.1 is a good start. If you can get the model number of the converter we could know what to expect. In general yes the voltage should drop to 13.2 to 13.6 in a few hours and the battery will be fine.

Find who makes the charger and ask them.

Hi 4005voltage,

Welcome to the forums.

Battery chargers for RV's are referred to as "converters". To answer your question we need to know the make and model of the particular converter.

Since you have golf cart batteries the maximum charging voltage would be best at about 14.8. It is unlikely the existing converter does that. I'm not saying the existing converter will not meet your needs.

If you hook the batteries up correctly the charger won't know or care that they are six volt.

If the charger/convertor is WFCO, replace it.

Install a 12V digital meter somewhere you can view.

I can't imagine 14.1 volts is a WFCO [emoticon]

Panel mounted digital volt meters are cheap on the internet. I installed a on/off switch on this one. Have a similar one in our 48V golf cart.
