Excellent video I just learned something a hobby shop didn’t tell me…why my new 4s Mojave would turn off after maybe 10 minutes sometimes 5 minutes..turned out I had a brand new battery with a dead cell when we check each individual cell…so the battery read 15.3v after I charger it plugged into my car it would only run for maybe five minutes then shut off that’s because the ESC was detecting a bad cell not looking at total voltage…Great video thank you,so after testing the bad battery we checked the new battery the hobby shop gave me and each cell was balanced all comparable to each other cell

Excellent. Thank you

How can you tell if it’s voltage shut down or overheated?

I played. A dangerous game. I'm new to rc my car didn't run that long. I would turn off the car and transmitter. Turn the transmitter back on then the car and I would run it some more. I noticed the battery was hot. Thanks for the video. I had no idea. I was running the 2s lipo all the way down. I know this because when I charged it it had 0 mah. Thanks again.

i have been into rc off and on since about 2013, i liked lipo enough to build my ebike battery out of lipo packs. i am trying to figure out how low to take the voltage. seems like i used to hear lipo packs should not be taken down to no less than 3.7v per cell. i just did a test and found that 3.7v at rest is almost exactly 50% soc, if you consider 3.0v per cell to be 0% soc. since i have six 6s packs, which is about 28lbs of battery, i cant justify only using about half the batttery, plus thats difference between 1.5hr of riding at 22mph vs 3 hours of riding

This is one of the reasons LiPo cells are rarely used for ebike purposes, we know a good amount about the ebikes and there's a reason most electric vehicles go with Li-Ion cells. They do just make more sense.

Good video. Once the low voltage cut off has happened, if you unplug and then plug the battery back in, will the low voltage cutoff activate again? Is it impossible to keep running a lipo down with a modern ESC?

@RCJuice

Yes, LVC will kick in anytime the voltage is too low. Once it kicks in you can get some "'bursts" of power from the ESC for a little bit, but it will stop working altogether soon after. As long as the ESC reads the proper cells then yes, it is nearly impossible to run down a LiPo too far during use with a modern ESC. If you set the voltage down very low (say 3.0V) and the battery is old then it is possible the voltage will drop down too far for a charger to recognize it, but you can "revive" that as well: kzread.info/dash/bejne/aKWWwbCwYZbOZto.html

I have a 8BL150 esc running on a Dewalt 20v Lithium battery.. runs great for a minute then cuts the power in half. I also have the Dewalt DCF809 motor. Any ideas why? Esc is set to 3.0v/cell

I have an xr8 pro g3 with a 3660 - 3600kv g2 motor. The esc keeps cutting power in my 2s when the battery is full. But with my combo the motor lipi limit is 3s, is the battery my problem?

On my Arrma Granite the LVC seems to be kicking in way too soon (around 50% battery life). Any Ideas?

Are you sure the ESC is in LiPo mode? The cutoff voltage itself is also usually adjustable, have you checked the ESC setting and have you also verified the battery voltage at cutoff?

So why won't traxxs tell me what the low voltage cut should be for there 3c lipo? The mamba is set for 3.2v. Is that ok?

@RCJuice

Жыл бұрын

Traxxas and many other of the big brands don't like to give a lot of these specs but yes, 3.2V is fine for LVC.

Took my truck out everything was working just fine then it stopped working my motor itself started to Signal alarm what would that be now everytime I plug my battery in and turn it on it beeps a couple times and then nothing responds not even my staring did I burn up my ESC

Sounds like you may need to calibrate your ESC (if you move your throttle trim on your radio it can also keep your ESC from arming, make sure your throttle trim is all the way down before powering up the ESC): kzread.info/dash/bejne/f32k2NuiaNnQeM4.html

Does cars that come with Li-Ion packs have appropriate lvc for Lipos? Or does Li-ion use different lvc point?

@RCJuice

LVC for lithium ion batteries is between 2.5v-3.2v per cell depending on the information source

I’m having a lvc situation going on now with my brand new erevo 2.0. It’s shutting the truck down at 3.9v per cell. I’m using 2 brand new 5200 mah 100c 2s lipos. It’s pretty annoying. That can’t be normal right? 3.9v ?

@@6spd85notch If you had cutting out under heavy throttle at all pack voltages then an adapter could be suspect, but if you are consistently hitting LVC at the same voltage then it is likely either the ESC setting is just where it is, or the packs are starting to sag once they dip-down in power and they are tripping the LVC. Does the throttle come back for a bit after hitting cutoff, or is it just hitting cutoff and shutting the whole party down?

@@RCJuice cuts down to part throttle. Erevos battery compartments are tough. I’m actually looking at another set of batteries on eBay right now. I haven’t had an erevo in a while because I started buying arrma trucks that fit almost any size batteries. I don’t have any other batteries that fit it. Puffing batteries don’t help the situation either. I’m going to order some 3 cell batteries and I’ll let you know what happens. As long as I’ve been into rc cars I’ve never come across this problem. I think the batteries are way overrated. Mah and c rating are probably exaggerated and like you said the voltage dips below the cutoff for long enough to trigger Lvc.

@@6spd85notch Correct, you are a lot more limited on the packs you can run due to the nature of the battery trays you are working with. At some point an aftermarket ESC may be a worthwhile upgrade, if for no other reason the accessibility is nice. Take a look at these 3S packs that fit those trays nicely: www.rcjuice.com/lipo-batteries/3s-11-1v/hobbystar-7200mah-11-1v-3s-100c-lipo-battery.html
