Should be in the manual. I don't recall but I set my junk to 3.2/3.4v. The bliss about cheap batteries is I don't care. Run em to lvc, then throw them in the freezer for 10 minutes. Rinse, repeat 🤷‍♂️🙄🍻
Never flown an rc, I suppose flirting with LVC would be a different risk.

Ok. Thanks.
Then I have a different question. Like I said, when I was flying I had my goggles setup to display the battery voltage in the lower right so I could monitor it. Is there a way to do that with RC cars? I have seen those fancy controllers with screens (like Sanwa and Noble), can they display the battery voltage? Or do you need special things to do that?
 
I believe some ecosystems have that. It is part of the telementery data. You would need a smart battery and an esc and receiver compatible with it I believe. Correct me if I'm wrong though, never used something like that.
 
I don't have telemetry on my 3VCS, but I believe most modern radios are capable of displaying Rx voltage on screen - you just need a receiver that monitors Rx voltage.

FRSky, Spektrum, Futaba, Sanwa, KO can pretty much all do it, so long as you have the relevant sensor and your radio is setup to display it.

My Taranis radio displays Altitude, Speed, Voltage, RSSI etc - but I'm wearing FPV goggles, where I can see that data in my HUD, as well as bearing and range.

When I use my fixed wing stuff, it's good to see on the radio screen.

When I switch my radio on, I see this;

I was being sarcastic about the batts in the freezer, my attempt at humor. But I do run to LVC most of the time, and have been known to "hot cycle" batteries where they're still "warm" when going back on boil (charge).. fuggit.
As to telemetry, ain't that when folks make stuff move with their minds? I no speak telemetry, sorry. I find too much gadgetry spoils the fun.
My $35 (15YO) Flysky radios are easily my favorite radios I've ever used. Nice HUD, easy to navigate/adjust. I never felt I needed anything more.
 
Nice ir's BTW, I've never had readings that low on my ping-pong amazon batts. Oh well, what can I expect for $15?

4600mah under 10 minutes, what are you charging at 20A?! I see 105f on the loaded channel and 101.1 on the other, was that the ambient temp, 101? Whew, too much for this guy! LOL

20A? I’m a professional. 40. 🫡🔥🙏

6.66C 😈

No doubt! Since I buy cheap, and lots of them, 1C does it for me. One day I might actually come acrossed someone with "good" batteries that might convince me they're worth it. Till then.. nah.
 
Heh, I charge almost all my batteries at 1-1.5C, I just have a couple for 1/10 stock racing I charge at 40A. It makes a pretty big difference.

3th and 4th cells are having problem?

Is that a fully charged pack? Those figure are pretty darned good! Try discharging the pack to 20% and then checking the internal resistance. It will be higher across all the cells, but if the same two are higher, then it indicates that they are the weaker cells. 👍
 
At that time the cells were about 4.10volts each.
93% as the charger shows in the picture.

Ironically some of the best batteries are the cheap ones


SMC and Liperior consistently outperform expensive premium brands for example.
