I bought an Earthx battery the other day for my 950se. Fit right in with no spacers required, nice and tight. Measured 13.81 volts out of the box. Temperature was low twenties this morning and she fired right up. These have the battery chg control thingy built in, so they should keep all the cells evenly charged, a problem in some other lithium batteries I am told. Happy so far.
