Brushless Setup Help

RE: Brushless Setup Help
My 3 chargers are the ones with a external power supplys, that way if my power supply fails, I can just replace that, without having to replace the whole charger.
And yes I have had a power supply fail from been dropped
Depending on things these chargers can be run off old computer supply's too, sometimes a cheap alternative

RE: Brushless Setup Help
Ive recently acquired a Venom Pro Charger and a Tenergy 3s 25c 11.1v 5000mah lipo. Some say 25c isnt enough but im doing wheelies like no tomorrow. I am running without LVC so does anyone know what V I should not fall below?

You don't want to discharge a LiPo below 3.0V per cell. The problem is if you aren't using an ESC with a LiPo cutoff, you can over-discharge the battery and ruin it. The advantage to using LiPo cutoff, is that the ESC is monitoring the battery's voltage UNDER LOAD. A battery's voltage changes whether it's under load or not. If you measured the pack's voltage statically, it would read higher than it would really be in use, and give you a false sense of margin. USE YOUR LIPO CUTOFF feature, it's there for a reason. Set it to 3.2V per cell.
Oh, and sorry about my mis-cue regarding 2C & 4C, and 2S & 4S. My bad. I knew what I was talking about, just not what I was typing! [&:] Sorry for the confusion, but the next poster pointed out my error.

Here's an external LVC I found. The guy in the post I got it from said it works great.

There are also LV Alarms that emit a beeping to warn you of LV.

RE: Brushless Setup Help
Thanks rob, im a little hesistant to solder in an external lvc at the moment. Where do the battery wires connect into? Im thinkin to invest in a venom LVC meter/alarm for only $10.
