i got the dueydog bone batteries from direct from the site,cost an extra $5 to ship to the uk, should last a days balling 2box's and at the end only take 2 hours to charge, comes with a charger and 2 of the bone batteries for $45........... thats like £20ish i could spend that on two tournies if i bought duracells from the "co-op" for my vlocity.
the gangstar chip turned up today as well, fitted it works like a charm, easier on batteries and has the nifty "gangstar spin" you press the button if its jammed and it automatically revolves backwards clearing the jam, i know the standard one is supposed to do this but i found it unpredictable, also has features like it stops putting tension on the stack after a set amount of time.
then thers break out mode for fast ramping off the break for 30seconds, i could go on but in reality i got it cos its pimpin
