Just another redneck barrel boat - 17 80lb minn kota riptide endurance test - success!

For this test -
4x - 6v flooded lead acid golf cart 208 amp/hr batteries = 24v at 208ah = 5kw/hr
minn kota 80lb riptide 24v trolling motor (running at 1/2 power)
water cooled chill block to keep electronics cool
This is not a "how far can I go on 5kw of battery" vid. This is how long can I run continuous at as many amps as possible and not overheat the wire, connections, motor, control, or batteries. The only way you can do this is run continuous for a long long time. People often do this test by running for an hour and then extrapolating to tell what will happen in 5 hours. It does not work that way. I can run this at 40 amps for an hour, but it will likely overheat the motor or control in 2 hours.
I ran 5 hours non stop at half power 500 watts ( 20 to 22 amps )
** I said in this vid that the trolling motor ran at 1400 watts full on, but that is incorrect. It runs at 1000 watts (approx 40 to 45 amps at 24v) full on. I know, google says it runs at 57 amps. I am measuring this 2 different ways, I never get more than 45 amps (unless after a long time if the motor heats up) even if I bypass the control and hook up the motor directly to the battery.
I believe I could go a little higher and run at 25 amps, but it would get much hotter and would not be much faster nor much more torque either, so not worth it. It ran the 5hrs with no trouble at all even through windy conditions. I believe it could do at least 2 more hrs and likely more. I will get an early start next time and find out. At the 500 watt rate of discharge, I should have 9 or 10 hours of run time. I used only half the battery's capacity this test.
