Great intel. Thanks, @tcarreon14. In the interim, I'm thinking that I can parallel two of those 48v10ah packs in you link to bring it up to a 20ah battery. If the dimensions are true as shown, both packs should fit by stacking them on their broadest side. And the total weight should still be about 9 lbs. less than the lead acid battery.

@tcarreon14, were you able to get richshop10 to sell a 48v20ah pack that fits the Oset 20.0?
