You can go below 3.7v, all the way down to 3v. But your ESC looks at the voltage as a whole. So if one cell goes to 2.9v and the other is at 3.1, you are hurting the lower cell. So it's best to keep a buffer there and stop running above 3.2v. I set mine to 3.4-3.6v.Thank you everyone on the information and the articles that you sent me. Don't worry, I have a LVC of 3.3 volts per cell and my battery hasn't ever gone under 3.3 volts, but from what I have been gathering, what I didn't realize is that it is pointless to run a car under 3.7 volts due to the drop in voltage. So just to clarify, on a regular basis should charge my lipo up to 4.2 volts and not let it drop under 3.7 volts?
That's a good idea. I usually stop mine before even hitting lvc, and 9 times out of 10 I am right around 3.8v. But I still toss them on the charger for a quick storage and balance.Full charge, cut off at 3.3. Then storage mode to 3.8 per cell when done. Or if your happy with the run times, full charge and cut off at 3.8. Then when it shuts off you’re already at storage voltage. I set my crawlers up like that.

And yes, you should always charge your battery to 4.2 to run your car. When done, storage charge to 3.7-3.8v

Thank you. You are correct, I meant milli ohms.your battery cells are not reading 135-160 ohms if it was they or esc would go up in smoke as resistance is to high. i think its in the Milla ohm range. 20 minute run from a storage charge to lvc unlikely

Thank you. I have managed to find a youtube of someone testing new 300mah 2s lipos. Checking 10 different makes the average resistance was 30-50 m ohms / cell. None of the batteries were as high as mine. I understand that small batteries have higher resistance but even so my resistance seems much too high for a 350mah lipo.even 130+ milliamps is 10x what id consider safe . i do have a few common sence lipo 3600 mah 35c that i like to run got them in a ticket draw back in late 90's they have so much punch they read 25 milliamp's used them in a xxxt with brushed 27t brushed on a tekin 420. there weight and punch woke them up set many tqs with them on carpet offroad
Usually need 60-80 amps to perform this. Its usually only pros trying to drop a couple ohms because of the 2s limit. My protek 6100's are all under 8 ohms. When they get to 15 ohm I give them away. Those guys will try to get that 8 down to 3-5. I don't do it for a living and won't risk try to burn one down. If I remember right my bashings and spectrums are around 18-28 ohms, those are 4 and 6 s. Not sure how 2-5 ohms make a difference in real world applications, but some swear by the extra burst they get.try a higher amp charge rate be careful .some say 10c charge rate can bring ir down.usually people racers like to see 4 m max
