I can't give you the "whys" (maybe Red can elaborate) but I noticed early and false peaks when slow charging with the Triton on several occasions, especially with new packs. Try charging at a higher rate like .8 amps you will probably notice the pack gets more of a charge. If the packs get hot at the low rates maybe you have a bad cell(s). I do remember reading something about a minimum rate for your supply to the triton (7 amps??)....may not effect it in theory...if your charging under 1 amp, but it may have to do with the proper functioning of the charger.
