SG Charging Rate

[Joster]

Hi All,

Yesterday I ran my 8 filar SG for about 14 hours. I used a marine battery for the run and a RV battery for the charge. The run battery was at 12.8 and the RV battery was at 12.06. At the end of the 14 hours my RV battery was up at 12.32 in the marine battery was down at 12.06. In the system I used a Dump circuit dumping about 1 AMP of current every second.

It would seem to charge rate is less than satisfactory with my current set up any comments tips or suggestions would be greatly appreciated.

Thanks,

Joe

I have a similar problem with my setup. It seems to charge more efficiently when I use 24v to run the system, and 24v on the charge end. I got a West Mountain Radio CBA IV which is a computerized battery analyzer that I saw at the 2013 Bedini conference. It helps to see graphically the steady decrease in charge time, and steady rise in volts captured in the charge battery. So far, the results aren't where I'd like them to be, but I can see the conditions of the battery improving.

I also think 14 hours is a long time. Maybe you should decrease the base resistance to allow more amps into the charge battery. If you have a variable resistor, you can put a volt meter on your charge battery and notice it will increase as you reduce the resistance. Also note an increased amp draw from the primary, and the visual representation by moving the meter probes to the run battery.

Good to know know Im not the only one! Haha. I'll try it at 24 volts and see. What is the current draw from the primary during your runs?

Also, how much was that CBA? Do you use it to chart the charge battery? If so I guess it holds up to the spike?

It was under 200$. I usually run my machine anywhere between .5amps and 2amps, depending on what i need to do.
