I think you have a lot of things to say about Quark Monster Pro 125B. Can I ask you to be more specific about the strengths and weaknesses about that particular ESC? I personally agree with you on that ESC having the + and - power wires coming out of the same place. And I think Quark should have made the case differently, so that it gets cooled more easily. Please let share your thoughts with me. Thank you ^^  |
Thank you. She is my life.
I'm trying to have a HV controller made. The engineer was going to do a 200A capable of 14S lipos, but he used sample boards that did not handle the AMPs. So I asked him to do a 60A, 80A and 100A. I like HV (12-14S) as it helps keep the temps down. I've talked other companies about this and they make it sound impossible to do. I'm not an angineer, but I know it's possible as I have a Schulze 40.160 (14S lipos), Actonic120 (12S lipos) controller that has car mode. The problem is that most companies want to make things smaller and smaller, but then they say hardware is not compatible. Kontronik did a fantastic job with the Jazz 55-10-32 as it has a car mode. It is small and freakish powerfull. I only hoped Kontronik would make the Power Jazz that way as well. There are very good MOSFETs out there and they need to focus more attention on them. I like the MOSFET found in my HW and I know Cyclone will have a controller with the same MOSFET. The SHV from Castle also uses them. Most people should realize that with HV you won't need 200A. You can still use 4S, 6S, 8S or 10S lipos if you want. You will be able to go out and buy a smaller capacity pack at a great price. The way some controllers are built though, you can still have a controller put out 200 or more AMPs for the bursts. Keep in mind, in order to get power from a 6S set up you will need more AMPs (22.2V x 200A=4440 assuming your batteries can put out that much AMPs), with 10S set up (37V x 120A=4440 now a good 5000mAh pack will do that), with a 12S set up (44.4V x 100A=4440 that's better) and with 14S set up (51.8V x 85.71A=4440). Now 4440W is a lot of watts. Most people are happy with 1400 to a little over 2000 watts and if you devide 2000W/44.4V you will need 45A to get it and 2000W/22.2 will bring that number up to 90A. Kontronik, Schulze and Actronic are the only companies with good HV (real HV not 22.2 volts) car ESC. I apologize for the long post, but I like HV

Edit: Also, a lower Kv motor tends to make more torque then a higher Kv motor does and one advantage of a electric motor is, powr from torque.
