Hi Philco and you can safely use the 60 amp ProNautic battery charger to charge your two batteries in parallel.

Because you are planning to use your generator to power the battery charger, I would recommend at least the 50 amp charger but the 60 amp charger would require less generator run time and/or replace more used battery capacity in the same run time.

BTW what is the make of your generator?

Hi Vlad and I don’t know much about the Optimate chargers but considering all other battery chargers are simply trying to play catch-up with the Sterling/ProMariner charges, you will find these chargers do a better job than anything else.

The generator is a Powermax. similar to a Kipor. 1800watt, Max output 2000watt. It has a 12 volt outlet as well as the 240v

Hi Philco and forget the 12v output on any generator. This is just a power supply and is next to useless for trying to charge batteries.

Using the 240 output to run a battery charger gives you the best results and you can easily run a 60 amp battery charger off your generator.

The 60 amp charger draws a little over 900w so you have plenty of 240 output left over for other things.

So happy to get good advice, asked a few places around about that but could never get a straight answer.

Hi Tim

What do you currently have in the way of 12v battery chargers. Dont want any thing too fancy. Prices etc

Regards Gary

Hi Gary and my apologies, I have only just seen your post.

I no longer carry battery chargers, for the very reason you put up in your thread, most people only need a basic type three stage charger and the battery chargers I was carrying were top end type units.

These were to expensive for the average usage.

Cheers, Tim.
