Just received my 5901 yesterday in the mail. After charging the battery up and plugging everything in it acts like the battery is low on power. Very slow moving and almost no power. Hardly scoops very loose play sand. Slew is very slow. I have 2 other batteries coming in the mail. Battery voltage says 8.10 volts (if im not mistaken shouldn't it be 8.4 on a charged 2s li ion?) Do i have a crap battery or is something internal wrong.
