Wiring diagram for the DRS1 receiver.  Wire colors correspond to wires on the harness.
The recommended battery is an 11.1V lithium polymer (lithium ion) 3-cell battery of 100 mAh or higher. In a test a 120 mAh battery will run a sound-equipped Forney for 40 minutes with the wheels slipping. Obviously, the larger the battery the longer the time between charges.
An on-off circuit to disconnect the battery is needed. This can be a plug you pull apart or it can be switch.
I recommend only using batteries with a protection circuit. This means do not use RC batteries because they will not have a protection circuit. Protected lithium battery packs come with with a small circuit board to prevent low voltage, over-charge, over-discharging, and short circuits.
Be sure to read the instructions that come with lithium batteries – they are not as tolerant as other types of battery.
I recommend removing your battery and charging them on a non flammable surface. Charge only at the recommended charge rate.

Frequently asked DRS1 questions:
Q: Can I consist DRS1 equipped units with my conventional DCC locomotives?
A: Absolutely. The DRS1 locomotive receives and obeys DCC commands as if it wre still connected to the track

Q: Can I program decoders in DRS1 equipped locomotives through the transmitter / receiver connection?
A: Yes, with Programming on the Main (Ops mode) you can program your locomotive. However, some decoders (e.g.Tsunami) will not allow changing the loco address in Ops mode. In this case you can attach the the decoder directly to the pragramming track. The DRS1 has a plug that can be removed and connected to an adapter to make this easier.

Q: Can the receiver send commands and power to more than one decoder? I have several locomotives with separate sound and motor decoders
A: Yes. You can attach as many decoders as the current limit will allow.

Q: What about automated control from cab bus equipped modules like NCE mini-panels, loconet, xpress-net, NMRANet etc.
A: These are all cab-bus or accessory bus devices. The DRS1 does not change the way the cab-bus behaves in any way – it is connected on the track side of the command station.

Q: Can I still run these equipped locomotives at my club or friends layout?
A: No problem. Simply bring along your DRS1 transmitter and attach it to the track with some alligator clips in an out of the way location. You can now use your freinds throttles to run your wireless DCC locomotive (be sure to run it on the floor just to show off!).

Q: How many receivers will one transmitter accommodate reliably.
A: There is no limit. The receivers do not draw any power from the transmitter.

Q: Is there a way to prevent locomotives from continuing to run all the way to the floor if they do leave the track,
A: Yes, grab them. This is a portential new danger for on-board battery power (and keep-alive circuits).
