If you watch during the discharge cycle, the GFX suddenly stops discharging at the full amperage when it takes the resistance measurement. That always happens at 120 seconds and lasts for three seconds.NCFRC said:NO , It has to calculated during a discharge cycle.
This is built into the GFX computer circuit of the charger.
My Spec motors pull 3.5-4.0 amps at 1.5 volts. If I ran them at 5 volts they may shut off my GFX! lolNCFRC said:#2226 spec motor with 4383 brushes and red springs with pull 2.8 to 3.4 amps @ 5 volts without a fan @ 16,000 rpm's .
Something is wrong with this picture , sounds like you power supply to your GFX is faulty .Tornado_Racing said:My Spec motors pull 3.5-4.0 amps at 1.5 volts. If I ran them at 5 volts they may shut off my GFX! lol
My spec motors pull 3.5-4.0 amps at 1.5 volts with a fan. I was just kiddin' when I stated they would shut off my GFX. Our ARCOR 19 turns pull 13-14 amps at 1.5 volts with a fan on our GFX with no problems.NCFRC said:Something is wrong with this picture , sounds like you power supply to your GFX is faulty .
Amp draw ''WITH OUT " a fan usually goes down slightly as you increase the voltage.
We built 25 of these for our track and all the amperage's @ 5 volt , no fan , were between 2.8 to 3.4 amps, there's no way this motor will kick off a GFX with a 20 plus amp power supply !!!!!!!
We raced last night and after checking our battery's after the feature, I guestimate we were pulling about 15 amps for 4 min , the motors were barely warm with 1.88 rollout.
Let me know if I can help , but something doesn't add up , our fixed 19's with stout springs / brushes only pull about 10-11 amps @ 5 volt and the GFX runs them fine.
