Voltage on your screen.

If using one battery for electronics only,(1 DF) how far do you let you voltage go down before chargeing. I have set my alarm to go off at 9.5. Have not let it go that far yet, but curious on the minimum.

Deep cycle batteries should be re-charged immediately after every use. This will prolong their life a lot.

Based on this chart, I would set your electronics' low voltage alarm to warn you or shut down when your battery drops below 11.5 volts. Unless you have an extremely short power lead from battery to the DF, there could be a sizable difference between the voltage reported by the DF and the voltage at the battery. The best way to compensate for this is to compare the reading on a volt meter hooked to your battery with the reading on your DF. Unless there's at least a 2 volt difference, you should probably increase the low voltage alarm setting.

With it set at 11.5, you might get a nuisance alarm every time you crank the big motor. That is if your df and motor are on the same battery.

Looks like he using a dedicated battery for the electronics. I would go with the 11.5 to start. Not sure you would even know when it got to 9.5, that would be a bad battery.

Man, talk about lack of reading skills....my apologies.

Thanks guys. Got it reset at 11.5
