You don’t adjust anything. In fact, bypass all of the thermostat shit and connect power leads directly to the heater element.
120VAC 1200-1500W heater element will draw around 400W @ 60VDC or about 6A. That’s decent enough load to burn off charge and get an IR measurement.from the battery? You can add more heater elements too (clothes iron, space heater) for more VDC Wattage. what's the difference if u wire those elements parallel or in series
In my situation for 60VDC battery pack expect about 1/4-1/3 wattage draw as the VAC rating.
For example 120VAC 100W incandescent lightbulb would be lucky to draw 25W from a 60VDC pack. Need stuff in the +1000W VAC range to be useful IMO.
I'm back to this thread after "popping" my hobbyking 350 watt power supply. The batteries could do 20 amps, and the charger, didn't think about the power supply. After 3 minutes my unease at trying such high amperage snapped. I feel I can blow stuff up left and right as long as I'm here to make sure the building doesn't go up and my nerves can take it.
I'll be getting the bulk charger going as soon as I read this thread again. Remembering not sure on the ground wire's importance or danger.
I was doing the two 6s packs seperately using the nicad on the charger and using the balancer on the side. I was doing ten amps fine but the nanotech aspec batteries say 8c so that was the lure into the problem for me.
Luckily I just got a multimeter as how else to know your voltage whe setting up,the bulk charger?
But the batteries I was charger with the Icharger before : I find a drop of roughly .05 quickly after disconnecting the cells from the charger. As soon as a cell hit 4.21 I'd cut it and find the cell at 4.15 and call it done. I'm surprised at how out of whack they can get when discharged : one pack at 3.51,3.53,3.54 and another at 3.57,3.58,3.58. I set up a low voltage alarm on my watt meter, which I've never heard,and the esc, but I'll see the 12s at 43.30 (43.00 is 3.6 a cell) and I'll do another hill and then a huge drop in power and the watt meter is showing the pack as low as 32. I have almost now power and don't know if the esc is shutting down (two tiers on vesc I think and I had them at 43 and 42 is off). The cells will bounce back to as you see above by the next morning, but if I simply leave the watt meter on them they will continue to discharge and I don't know if and when they would come back.
I've got the sp-320-48, it says, on the front, the only place it says anything, more so alludes, ..it can do 6.7 A at 48v. I'll be looking but at this point I'll be only charging at that rate.
