Second battery on rear rack

[reggy]

Hi thinking of upgrading to a 52 volt battery and 35 amp controller.

Anyone mount a second rectangle battery to the back rack? Is the balance of the bike changed allot?

Also where do you get quality batteries? I'm in Canada, but looking at the following:

I asked this question last month and got a lot of cool hi-tech feedback. You might want to look it up. Cheers, eh.
