24F?

Does anyone have a stock file for the G510 (no halls) which they could edit for me? I would like to reduce the cut off to 30V if that is possible. Assuming the logic hardware will still operate properly at 30V. Happy to PP $50 for a working file. Thanks. EDIT: Forget it actually because I will...

Did you use those for 20S 60A in the G510/M620 controller? I think the better ones might be suited to other applications. A really low RDSon would be ideal for something like a spot welder.

I will keep them all the same, thanks.

Do switching characteristics matter? The stock Chinese HYG064N08NA1B have low capacitance, gate charge and rise time values in comparison. I tried to match the values as close as possible to the stock FETs and it is impossible with the really low RDSon 100V FETs which is probably because the...

Please could someone recommend a high quality 100V FET which is suitable for this controller? It is currently using these: HYG064N08NA1B Marking Code: G064N08 Type of Transistor: MOSFET Type of Control Channel: N -Channel Maximum Power Dissipation (Pd): 208 W Maximum Drain-Source Voltage |Vds|...

Does anyone know if the controllers are any different in terms of efficiency? I saw a CAN PCB and it looked really different to the UART one. It looked like they had added current measuring on the phases. I am just interested to know if the CAN version is any better than the UART. I would...

I recently asked a seller from China who sells 0.2mm copper strip and other battery building supplies what they use to weld 0.2mm copper and the guy said this pulse argon spot welder can be used. Has anyone tried this...

Brand new. All 5x are between 0.40mOhm - 0.42mOhm. One of the threads needed repairing as it was damaged. I was originally going to use these in a 5S configuration and adjust the charge voltage with an adjustable PSU so I could regulate the welding current. I changed my plans and went with 3S...

Do you know if the centre of the needle bearing is supposed to turn? I need to replace my nylon gear and I noticed on the replacement gear the middle part of the bearing does not turn but the front and rear parts do. The needle rollers all spin but the needle cage itself does not spin like the...

Recently I have been using the DPX800S modules to charge batteries. I used to use the common 1200W/1800W "house brick" step up converters but the DPX800S is much more refined so I have swapped over to these. I have a faulty module and I wondered if you could replace the main FET with something...

This is probably a silly question but how do you connect the uLight to an isolated DC-DC? I thought you just disconnected the 12V from the controller and added the isolated DC-DC to those pins but when I spoke to Vasiliy he said something about leaving the +12V from the controller connected. I...

I think they were customer returns. They have inconsistent drift but there are none which are too bad. If you don't mind sorting them into groups and using a BMS which can monitor and balance without charging they will probably be fine. The Sony cells are completely fine and require no...

I am using the Nucular 24F. They did all the work. :bolt:

So basically the DC-DC became a short somehow when I removed the battery negative from the input? If I had a better isolated DC-DC is there anything wrong with my wiring? I had to order the same converter again so I think I will use a diode on the output and switch the positive. Can you...
