    Antispark - need some general info about FET's

    36V (25-42) Li-Ion The two SPDT switches (left side) should represent my BMS I bypassed discharge from my BMS cause its rated for lower amps than I will pull. However I want to cutoff power if any single cell group drops below 2,5v. N-Fets are my main power switches (antispark), and the P-Fet...

    BMS heat sensor?

    Hey I got this BMS from Aliexpress (http://de.aliexpress.com/item/36V-2000W-Lithium-Battery-BMS-PCB-10S-42V-Electric-Bicycle-Battery-BMS-60A-continuous-120A-peak/32459655141.html), it has a 2 pin connection for temperature sensor. But i dont know what I have to connect? Thermistor (5k.. 10k...

    Lipo blown up dunno why :(

    Hey;) These days I did my first rides with my diy e-board some midnight riding after I got everything working and couldn't wait anymore and the next day I drove it to work, then I drove home but in the middle of a steep part I noticed a power loss. I immediately stopped and saw that one of my...

    Would this circuit work?

    Hey folks, I'm not that familiar with electronic circuits, but fortunately I can ask here:) It should: -Switch on pos1: Batteries in series (2x1s to run an arduino) -Switch on pos2: Batteries in parallel (to charge them from 1s built in usb charger) If it works , which diode will I need? If...

    Noob Hubz!

    Heyo! It took a while, but now I finally decided to build an Electric Longboard. I live in the Alps, and I'm an avid snowboarder but miss that in summer :( This will be my first E-Board & R/C project, perhaps I need some help, thats why I create this post. And to give you a little back, learned...
