i use one of those aluminum BORG looking integy dischargers (30amp) then equalize and condition on my rayspeed discharger before i charge up again. (of course i allow for the packs to cool down)
if i want numbers.. i throw it into the reedy quasar pro, and discharge (20 amps only) and it'll give you some numbers, average voltage i think and remaining runtime..
35GFX guys have the same thing but more features (discharge curve) and stuff. you get what you pay for!
