Battery limitations for ax1500

11 years 8 months ago #29524882 by kjy423
Hi,
I\'m using a 37V Lithium Ion battery with the ax1500. When fully charged, the battery is almost 42V. When I attempt to use the battery at full charge, I cannot activate my motors, but I can still read the controller through the PC connection. Is this voltage beyond the specs of this controller? If so, can you recommend a way to use this battery or will I have to change it entirely?
Thanks!

The controller is rated at 40V. The battery voltage is measured by the controller and an overvoltage detection will be triggered if above 42V. At that point, all output transistors are turned off. Measure with a voltmeter the exact voltage of your charged battery. Compare to what you see in the Roborun screen. It may be that you are just a volt or so above the limit. If possible, let the battery discharge a bit and reconnect.

Thanks for the quick reply! The multimeter shows 41.8, but the console shows 42.1, so it looks like the protection is activated. Is there any way to adjust this in the controller?
