Re: Tesla 18650 question

Right BT-C3400 is all over the place with results, very unreliable and heats up the batteries even at 0.5A disharge. Would not suggest to anyone. Yes iChargers are awesome !

Re: Tesla 18650 question

https://cdn.pbrd.co/images/H8hErJ0.png Allright, managed to hook up 206B to the laptop and attach the temp sensor. The only 18650 holder I had was cheap chinese one with thin wires, that explains the voltage sag, however, my goal was to check the temperature. So here is the discharge graph at 3.5A....

Re: Tesla 18650 question

Will see if I can hook up temperature sensor to 206B and link it with the PC to get any useful data. Then we can evaluate.

Re: Tesla 18650 question

Amberwolf : I am using Opus BT-C3400 to discharge them at 1A and for more discharging power I use iCharger 206B, so current and capacity measures comes from these chargers. Hillhater : Assuming my inside temperature is 25C and your chart data, by the end of the discharge cycle I would get 55C which...

Re: Tesla 18650 question

Okey, discharged another one at 3A and did not noticed any difference in heat. I'm assuming that it's just a working temperature. I can keep my fingers on it as long as I want, it's hot but not burning. Too bad i don't have a IR temp meter.

Tesla 18650 question

Hi guys, got a tesla module and took it apart, measured some cells, comes up at 3000 - 3050mah - good, however, when discharging at 1A, which is what, like 0.3C, cells do get hot. Does anyone has experience with these cells? I had an impression that I could do at least 1.5C to 2C without them being ...

Well if I buy just a motor, then shipping is 60 from China, but you're right I can probably lace it myself. Well, does anyone sell Q100H in USA anyway?

Re: q100h 201 vs 260rpm torque question

Got it, so it makes sense to get 260rpm version because of the small difference in torque. Well jumps, hopefully little Q can hold about a foot or so assuming I will not be spinning motor while jumping, it's mostly to help me to gain speed before uphills. The goal here is to build as light as possib...
