Quote:And with all 10 batteries, you would have a freaking 20 amp hour supply. This would run a telescope and even a dew heater for several hours.
Quote: They are connected in series. Connected in series, you get 13.4 volts with 20 amps of capacity.
Quote:The capacity is independent of anyting else. If you have 10 2 amp batteries, you have 20 amps of capacity. It does not matter if they are wired in series or parallel.
Quote:Explain this then.Here is a 8 Vdc pack using 6 Enelope batteries.The picture is showing a Multimeter set up to measure 10 Amps.Note that this 8 volt supply is pushing out 5.75 amps.Now this is not mouch different than a short circuit, and this would run down the pack to zero in about 2 hours. As time goes on, the current will of cousre fall, but as you can see, the output of the pack is not limited at all by the capacity rating of an individual battery.
Quote:Well, the battery is not shorted really. It is just running though a low resistance load.Knowing the voltage as being 8 volts and the current as being about 6 amps, we can calculate the load as being 1.33 ohms. But the meter leads start to get very hot within about 30 seconds, so I am limited to short periods becuase I don't want to melt the meter leads.Each battery is putting out .5 amps and they batteries don't heat up nearly as fast as the meter leads.
Quote:Each battery is putting out 5.75 amps if it wired in series. The circuit diagram is simple, all the current passes through each battery.

Quote:Of course someone implied earlier that you could not get more than 2 amps out of the pack if the batteries were wired in series, so maybe my meter is incorrect or something.

Quote:Best demo I've seen is the early electric submarines where batteries were switched between "Group up" and "Group down", short and fast vs long and slow.
