Hey Vlad im using pretty much exactly the same setup for my board based on this design but I had a couple questions. First off my 24V PSU doesn't have an IC controlling the current limitation, its a lot simpler and only has voltage regulation, so I was wondering how you control the amount of amperage the BMS draws? I had a 3S BMS that drew different amounts of current based on slightly changing the voltage higher or lower and I was wondering if it was the same principal here. If not would I be better off using a 5A constant current module for it?

Hi KaeptnBalu, I really like your design, though I was wondering if I could re design the PCB to not use the MOSFET gate drivers and instead just use ~10K resistors to drive the gates of the MOSFET's. The switching time would only be a few milliseconds so I would think it would work fine. If theres a reason that your using gate drivers instead of just resistors please let me know!
View Instructable »Also if you wanted to use an even more efficient MOSFET to create less heat you could use the IRF1324S-7PPBF. It has a RDSon of only 800uOhms/0.8mOhms which is crazy! Link to datasheet, http://www.mouser.com/ds/2/196/irf1324s-7ppbf-935685.pdf

I really like that design, though its not as pretty as mine lol ;)

Thanks! Yeah its really useful, wish i had built it a while ago but ey you know what they say, if it broke dont fix it!

Lol my power supply is anything but new, I think. When I bought it the fan grill was completely covered in dust and I mean like a thick layer of it. But yeah I guess it varys with PSU. Also those aren't 7 segment displays its just a cheap 3 digit voltage meter, you can buy them in ebay.

Thanks for the instructable it helped me a lot with my PSU. One thing you forgot to mention, or it didn't apply to you, was that you have to connect the 3.3V brown sense wire to the 3.3V rail or else the unit wont turn on. Idk if this apply's to everyone but my unit would only turn on for a second then turn off when it wasn't connected. Also added a LM2596 buck converter in my unit so I can have a adjustable voltage output. I also used 5x 15Ohm 1 Watt resistors in parrell to get a comparable 5W resistor then I used another bundle of those 15Ohm 1Watt resistors and added it in series to have a total of around 10W at about 6Ohms.
Looks awesome! One thing you might want to consider if you don't want to use an Mega and instead use an Uno or Mini is to use shift registers to theoretically expand the number of I/O pins. Other than that really cool instructable! I may consider doing something like this in the future but using an ESP8266 because or router is on the opposite side of our house.
