Battery Endurance Tests - Peter Vanvliet

10/1/2013

 
Here is a report I received from Peter Vanvliet. His latest run time from a 2 AH battery in an S-scale loco is remarkable and demonstrates the benefit of a good motor and mechanism.

Earlier this year I installed the S-CAB system with double-battery into my S-scale American Models FA-2 engine. It was very hard to control the speed. I subsequently had Dave at NWSL install a new motor in the frame. He used a "20x32" motor.
I converted the loco back to S-CAB. I then fully charged the battery and over the past two days I have given the engine my endurance test. I ran it back and forth my layout, about 20 feet each direction. I just kept flipping the throttle's direction button at the end of the line. I had momentum set up in the decoder. Over the past two days it has run for a combined total of six hours and 15 minutes. I have grown tired of having to watch the engine and flipping the throttle, so I am stopping here, but I would imagine it can keep going for a while longer. My layout has no track power on it at all.
So, for my three engines, to sum up, running light on unpowered track, I have these results:
950mAh = 1.5 hours (NWSL motor)
1000mAh = 3 hours (S-Helper Service unbranded motor)
2000mAh = 6.25+ hours (NWSL motor)

    I'm a retired electrical engineer, but still spending more time on engineering than on my layout. These days, it's mostly about applying radio control and battery power on smaller scale layouts (HO, On3, On30)
