ESC to LI-PO charger
When I wake-up today, I inspired the schematic which is the very high speed 3S Li-Po charger could be made by BL ESC circuit.
Now, I made the schematic and I will program it.

Help about bldc starting
i am having problem with understanding the starting phase of bldc motor , i have read we have to bring the rotor to a known position , what is the known position ?..and how to do it.
please also explain how to energize the high side mosfet , can we directly connect the high side mosfet directly to the controller, simply speaking i have problem with understanding the driver circuit!

>what is the known position
RC Permanent magnet BL motor does not synchronize the drive phase.
Especially at the starting.
You must study the working of RC BL motor.
Then, you need to know the rotor position to drive them.
>how to energize the high side mosfet
>can we directly connect
you must read the data sheet of the MOSFET.
V-gate source concerns with I-drain sorce.
It is easy for you to solder MOSFET.
You should not write the simple question on my blog.
The main reason is I do not know what you are without your introducing.
Are you a student over 16 years old?
