![]() ![]() But with a lower current limit it slows the heating. Low rpm (hills) become the thing that destroys the motor when you overvolt. The effect isn't bad at high rpm, but at low rpm you get a doubling of heat. The big problems come about when people increase the voltage, but leave the current limit the same. Going from 24 volts / 30 amps to 36 volts / 20 amps (or 10 amps) should be fine. the more you increase the voltage the faster the motor spins and that causes arching across the brush / commutator interface which wears the brushes faster. Now with brushed motors there is the issue about maximum rpm too. If I have to I'll start pulling out all the charts to explain this more fully, but the short answer is that it's current that actually does most of the damage. So, worse case scenario, I should be able to at least go up a few volts over the standard 24v without changing the controller. I do have a variable power supply that is adjustable up to 50v at 3amps, so if I do not hear back from anyone, I will hook up the supply to the terminals and test to see what the upper voltage limit is that I can use to supply my system. ![]() On my controller is printed the following: DC Brushed Motor ControllerĪnyone know if this controller will handle a 36v 10ah batt? I would really like to know before spending $290.00 + for a Ping LiFePo4. SLA 24v 10ah ,Brushed motor controller (standard setup).Īfter searching on the web and in other forums, It appears that some currie owners can run 36v without changing the controller, while other cannot. I want to up the voltage on my currie bike. I'm new to the forum, so 'Yes' I did search before posting and making a new thread. ![]()
