I think "preference" might be more appropriate than "excuse" Tony?Tony Walsham said:For those that are concerned about operating signals and points with battery R/C locos and no power to the tracks.
Don't worry. There are other ways of controlling them.
Air power for example.
Simply run air tubes to each controlled device from a central control panel controlled by solenoids. Easier, simpler and less expensive than having a separate DCC decoder for each turnout and/or wiring them in from a central command station.
One connection at each controlled device and no wiring to fail.
Next excuse???

Did you get those batteries from Cliff Peter?whatlep said:I think Devonian sums matters up nicely.
To follow up my post re my own system's battery life, I think I have sussed the problem. This afternoon I intended to do another test, having rewired my Stainz to avoid all the installed circuitry (so no front light). As expected, my AA cells were flat (after 3 weeks without use) so I charged them up. The same test train as pictured worked for precisely 10 minutes, then stopped dead with no power. I suspect that - as noted in an earlier post - my AA cells have been fried due to current draw. I am now about to risk some Hybrio cells to see if they fare any better, but I think the long-term answer has to be a 12v sealed lead acid cell which, intriguingly, is cheaper than 10 AA cells! I'll report back when I have some more news.... 8|

Hi Tony. The AAs are 10 2600mAh cells labelled Bluebird and part of the system supplier's kit. As you surmise, they are in a spring holder, but that too was brand new about 4 months ago and is still bright and shiny. I am reasonably sure that the cells have failed in some way. It may not be all of them, of course, but I haven't had time to check each one yet.Tony Walsham said:Peter,
What capacity are the AA cells?
What brand are the AA cells?
Without wishing to be accusatory or condescending, did you isolate all the loco track pick ups before wiring the batteries into the loco circuit?
Whilst you can use spring holders for batteries it is ultimately not a very good idea. Where the batteries contact the springs can corrode and when it does, a greater resistance is created. This leads to heat build up and eventual spring failure. If the current draw is going to be over 1 amp use tagged cells and solder them together.
Another thing you may wish to consider is the weight. A lead acid installation is often heavier, this could be an advantage if mounted in a loco and more tractive effort is required but may have an adverse effect run time. If in a trailing car then the extra weight is usually bad news.whatlep said:Regarding the sealed lead acid cells, Tony's words are very helpful. It's easy enough in UK to get 12v 3.4mAh lead-acid cells which are cheaper than the equivalent AA cells and - obviously - have a longer nominal run time, but I will have to think about the voltage implications before taking further action. This battery stuff isn't as simple as I expected!
