Some of the  large scale guys have installed plug in charger sockets on their trains to recharge their batteries without taking the batteries out of the train. If they can do it so can we, just need to find smaller components to do the same thing.

Woodie,  can you use one transmitter to control more than one loco? Or do you have to buy a separate transmitter for each loco?

Bob-you could recharge batteries with a "charging track" perhaps in front of a coaling station or water tower. The loco would have to be oriented for the correct polarity in the charging circuit and you would need to keep the wheel pickups to transfer the charge. You could install a dpdt switch in the battery circuit so when you pull up for "fuel", you could switch the power routing. I suppose that you could have a trickle charge on the rails of the layout and run while charging, but wiring the track is something r/c is supposed to do away with! I do know of one fellow who did not disable the track pickups on his loco and fried his board when he turned on the power pack to run a dc loco. I believe that for the safest and best operation, the loco pickups should be disabled and then you can run on a dc or dcc layout with no problem. It would be nice if an r/c expert could chime in on this subject and put forth some ideas. The Lithium batteries I am using provide hours of service before needing a charge and don't lose the charge even if it is a couple of months between operating. Also, Lithiums don't have a "memory" like other rechargables, but they are costly. My batteries are built into the locomotives and when I need to charge them, I do it on the workbench with no disassembly. How long do these batteries last? I will probably not need to change them in my lifetime so the cost becomes manageable.

Hope this "clears" something up, maybe it will spark more research in eather case, discussion is great!

Larry-I imagine you can run more than one loco with one transmitter. Bob is working on that and maybe he has some ideas. As for me, I have 4 locos and they are all on the same frequency but since I am one guy (engineer), I only run one at a time keeping the others turned off. When I want to change locos, I turn one off(get down out of the cab) and get another loco turned on (climb up into another loco) and get to work. I have a friend who can run 2 locos at the same time by himself with 2 transmitters, but that ain't me! I can only control one at a time, maybe that's my disadvantage, but I believe that only one engineer can run one loco at a time-in the "real" world. Whatever you do, have fun doing it!!!

PS-my railcars run off different freqs so if I have visitors, they can run a loco and I can follow with a railcar-just in case the dadgum loco starts a "fire" along the way!!!

Another question comes to mind.... if I just want to lean back and watch the trains chase their tails, how can I do that with the spring loaded controls of the transmitters.

Larry,

 

The transmitter I have has a little ratchet you can add that changes it from spring loaded to "stepped" positions.

Larry-as Bob said, there's a little rachet & spring thing that can be removed and the throttle will stay in one place. I believe Bob is working on a way to use the steering outputs on the LOSI boards to control another loco on the same frequency with the same transmitter!!!! Oh Bob-have you figured this out yet???? There is a tiny r/c helicopter that has a very tiny 3.7 volt Lithium battery that is about the size of a dime and can be recharged 1000's of times! I have used one of these in a little r/c bulldozer I built and it can be hidden in small models. There is a larger battery for a bigger copter that can be used in small spaces but I haven't messed with this one yet. Here's a space saving idea from my friend Joe Bostick for guys using 9 volt alkaline batteries-take the metal cover off the power cells, remove the snap hook ups on the top, solder wires to where the snaps were and install. Doing this saves about 1/4 inch length and maybe 1/8 inch width. The battery still works like it should and lasts as long as it does. I used to get the little 3 volt Lithium camera batteries (CR-2) to run my early r/c stuff and I was getting 6 months or more on one set of 2. I ran my locos in several shows on the same batteries. I have found that my larger 1:32n20 locos need the "oomph" that the rechargables provide, but 9 volts or the camera batteries is just fine for most HO or On30 stuff. Be on the look out for other small batteries, technology changes almost daily!

I haven't worked on the 2nd receiver yet. I'm getting ready for a trip so it might be a week or two before I get back to it.

They look like watch batteries Don....... You know the kind of watch that has the little Solar collector that constantly recharges as a trickle to extend battery life.

Similar batteries are also used in the Laser Level market/Calculator market and Yes, even the Lighted Fishing Bobber market :)

How About Cell Phone Battery Packs??? Seems to me they hold quite a charge and last for years. The smaller cell phone battery packs would easily fit in a Shay climax or porter, particullarly if you had an all weather cab..........they could certainly be made to fit in a shorty tender also.

Heres an interesting tidbit on batteries
Service Life means "how many charge cycles will the battery last before it won't charge anymore". Go to our "Battery Guide" page to see how the chemistry a battery uses affects its service life. All newer cellphones use Lithium Ion (Li-Ion) chemistry, or the more expensive Lithium Polymer (Li-Poly). Newer chemistries will take more charge cycles, so while more expensive, they are usually a better value.

 

Heres an example of an inexpensive (comparably) cell phone battery..Lithium Ion that has over 3 hours of talk time...note the battery size of 73mm x 45 mm x 10mm

The little nickel batteries are the same used in many rechargable toy items like tanks and cars but they don't deliver sustained voltage or amperage that we would need for model railroad motors. The cell phone batteries would be a better choice-they are Lithiums and can be recharged over 1000 times! The same technology is being used in electric model aircraft, they supply high discharge and long life and are small and light. If I could figure out the complicated photo bucket thing, I would send a photo...but alas...If anybody is interested in photos of these things and size comparisons, drop me a line and I will send an uncomplicated attachment photo of what I'm talking about. As I said, the Lithiums are a bit costly, but you will probably never need to replace one. Keep searching, there are many batteries out there that can run a loco and be hidden in the cab, etc.
