There is really no excuse for a battery mfg not matching a two cell pack very closely but some cheap ones might not be. Some people here think the issue of fires won't occur with lipos used in trains because they are used so gently. They believe it's only the RC guys that have problems because of high current draw and fast charging. To some extent, they are right. Those use regimens do increase the risk of imbalanced packs. But...Samsung had a problem with their phones that became big news and so have some people had problems with their vapor cigarette devices. Those people are using their batteries even more gently than a train. 
It has little to do with use and everything to do with an overcharged cell. It can happen due to imbalance, especially over time. It's gradual but it can add up to disaster. Just for the heck of it,  occasionally balance charge your multi cell lipos. It's better to be safe than sorry and it's not that hard nor are balancing chargers very expensive, these days. 
I'm not really talking to you here, Bob but more others that may be reading this discussion.

Mike,  Agree with your comments.  Overcharging is the usual reason for battery failure.  Relying on a battery protection circuit (BPC) as often recommended and used in cell phones and most other portable devices can be risky.  I use fully adjustable quality chargers and can observe the charge on screen.  Most cell phones use a simple charger that never stops providing current.  If the BPC fails......
That said a BPC is valuable to provide low voltage cutoff. Suggest any further general discussion of battery management and RC use be made in the Radio Control forum, unless it is specific to Geneseo Rwy.

With the addition of the fourth operating area I just could not help myself so built another little steamer.  It is another side tank from Shapeways with the same radio gear as the other three.

Now that the track is complete in the fourth area, Geneseo East, and I have finished engine #8; it is time to add some structures.   Began work on a new industry.  Originally I thought about building a distillery but then occurred to me that my layout is set in 1927 and there was this thing called Prohibition.  Not sure what it will be yet.  Plan to put a large tank on the roof.

Added ends roof and dock to the front wall.  Beginning to take shape.  After I get the super glue off my fingers I may be able to carve the bricks on the ends.  I admire those who have the ability to plan and design.  I seem to always just begin building and then be surprised by the result.  Generally means a lot of false starts and rebuilding.  I did not know I was going to have a loading dock.  After I looked at the wall a while it seemed the lower section was out of proportion with the upper.  The dock adds enough at the bottom to balance it out.

Painted the ends, weathered the brick and added a little signage.  I think it will be a keeper.
