Put a Shori in my 620. OEM weighed 8.9lbs, Shori 2.3. Even @ $189.00 it's the cheapest weight loss purchase yet by far. Since it's high on the bike you can really feel the difference.
If you use their charger (or another brand with the proper cables) you can cell balance. I haven't bothered yet, but will check it and if needed use my iCharger I have for my R/C stuff.
