UPDATE: I learned from the vendor that the batteries do in fact have JST-XH connectors, which were washed out in the images.
The batteries I'm considering, a set of two, can be seen at:

Any opinions on the price vs. quality of the listed batteries? The seller has an excellent rating with their buyers, if that means anything.
