I’d like to have a spare battery with the same JST connector for the Electron. Anyone know what the size is?

The connector type is JST-PH.

How many MM, I am looking to get a lower power battery (size constraint) . but the batteries while coming in “JST” are multiple mm sizes from about 1 to 2.5

the ones i get are 2 pin JST-PH which come in 2mm-pitch, if that is what you are asking about.  
[http://www.jst-mfg.com/product/pdf/eng/ePH.pdf](http://www.jst-mfg.com/product/pdf/eng/ePH.pdf)  
however it has been necessary in the past to buy a battery with a different connector and then swap it out with a JST-PH. not all batteries come with a connector or the right connector.
