Hello from new hampshire

[Pete1942]

By way of introduction, I am an retired electronic engineer living out his retirement lake side in New Hampshire. Just shy of a decade ago, I purchased a Segway X2 SE, and today I am embarrassed to say I have gone through two sets of batteries and have a warping 5 miles accumulated on it. The first set was pure neglect as during the early time I had two total joint replacements and the segway was the last of my thoughts at that time. Once I was back to getting around, I wanted my segway as fast as possible and selected the 11 amp set. Following the sticker shock, I took very good care of this set. Even bringing the X2 down to the house during the winter.

This winter I lost my second set and while looking for a solution, is how I found this forum and the wealth of information within.

A quick search shows:
E042 error which is CU A - BCA down

So it seems that the A side control board cannot communicate with the battery.

There are 2 likely reasons:

1
A bad battery

2
A dirty ( or broken ) connector.
Or even a loose wire inside.

Then there's lot more obscure types of errors.

Good Luck
