I would like to know if controllers in general have overheat protection where they shut down & specifically whether or not a CYCLONE controller has it. I have a complete new Cyclone system--a 650 watt & the controller is remote to where I cannot feel it while riding. On one of my 1st test runs I had just climbed a steep bridge (I had climbed it earlier & was on the return trip & some time had elapsed--1/2 hour or so) came down the slope and traveled a few blocks & the system shut down. I never saw a yellow light but may have missed it. When it stopped I turned the throttle wide open & got a red light so I pedaled home. @ the I was thinking the batteries were low so I put the charger on & much to my surprise the batteries were fully charged w/ 1-1/2 hours!!! (I did not think to feel the controller at the time---if it happens again I will) The other day, from a yellow light condition, I charged the batteries to full charge & that took 4 hrs. I have a 24 volt 6 amphr charger & am charging 2-24 volt 33 amphr batteries for a total 66 amphrs @ 24 volts.
The next time I have a full charge I am going to take a voltage reading & the same when they are discharged to the yellow condition for reference.
I have felt the controller after a flat road ride & it is hardly even warm.
Any information and/ or comments would be greatly appreciated.
The server won,t let me edit---I forgot to say they are SLA batteries.

What is the current limit on your controller? At 650W and 24V it is likely trying to draw around 30A.
SLA batteries are generally AHr rated for a 20 hour discharge period and the rating decreases substantially when higher currents are drawn - eg a 20AHr battery may only give 10Amps for 1Hr. But as you have 2 x 33Ahr batteries in parallel they should easily last an hour and is not likely to be your problem.
Have you checked your wiring? At those currents a small resistance can make a big difference to the voltage seen at the controller.
