I have a mongoose dolomite fat tire bike and I replaced the rear wheel with a 72 V 3 kW motor hub. It is awesome. Has plenty of torque off road and a good top speed of about 44.9 mph. I'm only using 3 multistar 6s 10a 10c lipos wired in series For 72 volts and I'm using XT 60 connectors. Going by the hub motor specs I'm only drawling about 41 A. I did order 3 more batteries so I can get 20 A at 72 volts. I wired two sets of three in series and then parallel those two 72v at 20 A. The E bike is awesome only using 10a of batteries. Once I add 10 more amps of batteries Shouldn't it be even faster and more powerful? Also, Do you think it would be beneficial to upgrade my connectors from xt60 to xt90 as well?
