Re: 40T, neodymium magnets, plasti dip cycle test

took that 5mm pack to the hill i test the batteries on and pulled 47amps (almost 12 amps/cell) no problems then paralleled to the 7.5mm battery went for a 8km ride. the trike is set to 3000 watts, 8p means less volt sag so the max amps were 44 (5.5amps) packs were the same temp and no issues

Re: 40T, neodymium magnets, plasti dip cycle test

Back iron on the rear of the magnet would guide the field lines on the reverse to give a higher surface tesla on the magnet 🧲 so it should increase pull strength. I wonder if theres small enough magnets available to create a hallbach array no back iton needed it could double the pull to the cell an...

Re: 40T, neodymium magnets, plasti dip cycle test

dont need back iron, theres enough in the can bigger/heavier the magnet, the more lbs of pull required to keep the weight of the magnet in place been trying to go as small and light as possible 7.5mm magnets with 0.1mm copper ill do a test when i get it to see how many amps it can do before the conn...

Re: Help with choosing the right battery for powerful motor

if youre tight for space id go with a 17s/61 volt battery
not what other people call a 60 volt battery, 16s is 58v not 60v

the difference being how the bike feels with a dead battery

if youre using 18650's, 17s8p or 17s9p of a higher power cell rated for 3000mah or better is what id be looking for
