Hi all out tonight running my P tunnel noticed after 45 seconds boat slowed to less than half speed brought it in checked voltage each of the 4 cells was aprox 3.99 v put it back on charger took 700 mah to re charge .To make sure this was a lipo issue put another pack in and ran for 3 minutes AT FULL SPEED with no issues. What can be going on with this lipo ? Regards Andris Golts.
