Re: [RCSE] 6 volt battery for retreiver
If you're getting a new retriever,or changing the motor, it seems like a 12V wind is in order. I wonder if there isn't a way to play with the existing windings to accomplish the same thing. On a slightly related topic, I've discovered that for winding line onto the winch at a reasonable speed, at least on a 12V wind, a battery charger is nice and slow. Since the charger is probably current limited, it might work for the usual 6V wind as well. To tell the truth I don't recall which setting on the charger I used, 2 amp or 10 amp at 12V, or the 6V setting. Probably if you lay out hundreds of yards of line in the grass it won't have enough oomph. RCSE-List facilities provided by Model Airplane News.

RE: [RCSE] 6 volt battery for retreiver
Hi Jim - what I did for my Rahm retriever is get 2 big honking diodes from the surplus store and put them in series with the power line. This cuts the voltage down so the retriever runs nice on 12v. There are also cheaper alternatives, I think on RCGroups there was a discussion about using a home made resistor to do the same thing. All it was was a bottle with some lower gauge wire in it filled with water as a heat sink run inline with the power line. I hated getting and maintaining a separate 6v battery, plus if you used it up, there are generally no spares just laying around. I can give you pics of my setup if you want.

It should have about 50 to 60 amp hours of capacity. This will be a reasonable sized package - not too grunt heavy! Up to now I have been using three Trojan T-105 for the winch and retreiver but they are old and tired. Everyone else around here uses 12 volt winch batteries in parallel for various reasons. Charging is one of them. So I might follow suit but I need a smaller retreiver battery since I don't want to lug a T105 if not required! 12 volts makes the retreiver run too fast. The new fully automatic retreivers work very well but the club budget will not stand that this year. Any ideas? Somebody has to make a reasonable sized 6 volt battery larger than the 20 AH things for motorcycles. Thanks, Jim

Jim and Jim, Another thing you can do to slow or speed up the retriever is change the gearing ratio of the pulleys being used. The one I built was just fine for speed, it's the same the TPG uses, sized from the plans the designer sent me. Sal Peluseo.

Jim, Buy a cheap set of jumper cables and run the retriever with these hooked to a 12 volt battery. I ran my Rham that way for several years. If you have two 12 volts hooked in parallel, just use one of them for the retriever.
