Small battery w/ spring connector

[bungalow]

I have an aspire cfvv 1600mah and I love the spring connector for screwing on my genitank mini. I usually prefer using my vision spinner when going out though cause its smaller, easier to carry around.
Anyone know of a smaller (1000-1300mah) battery with a spring connector?
Also one that'll line up nice with the genitank mini, the vision spinner isn't flush with the tank but the aspire is perfectly flush.

AFAIK, there is no eG-class battery with adjustable pin--Aspire is the first one, but it is huge. The new MVP3 is supposedly going to have adjustable center pin also, but that's not what you're looking for.

Sooner or later, an adjustable center pin will become standard on all batteries and toppers, I hope. 'Bout time.
