LIPO SETTINGS EXPLAINED (WIKI)
NEVER DISCHARGE A LIPO BELOW 3.00V AND NEVER CHARGE A LIPO ABOVE 4.20V
4.21V 4.22V can be ok if balancing, 4.30V should be flames!!!!!
It may even be that the charger is reading off by a few volts.
NEVER STORE AT 0% 45% - 65% is acceptable
Nominal voltage is the default, resting voltage of a battery or pack. It is not, the full charge voltage of the cell or pack.
LiPo batteries are fully charged when they reach 4.2v/cell, and their minimum safe charge/dead is 3.5v/cell. 3.7v is around 1/4 of the battery cell and that is the nominal charge of the cell.
A Single LiPo cell has a nominal voltage of 3.7V. A 6S Lipo, that means that there are 6 cells in series (which means the voltage gets added together).
This is sometimes why you will hear people talk about a "12S" battery pack - it means that there are 12 cells in Series. So a six-cell (6S) pack is 22.2V nominal, a twelve-cell (12S) pack is 44.4V nominal, and so on.
Battery Voltage Cutoff Start and End Values
Battery Voltage Cutoff Start and End Values on your ESC are set at Better.
End is when the system stops giving you power.
This means you are now walking.
The Cutoff Start is when the system starts to lower your power output/speed/throttle. This will feel like a car running out of gas, and eventually wont move forward. You should still be able to brake, but best to stop before you reach 0%. Or your Cutoff END.
No single cell drains at the same rate as the rest of the pack. Some cells may drain beyond the set limits. It is recommended to add some head room to the limits of your battery pack when setting these cut off values. The below values are choices you can make based on my own personal experience but is best to choose a setting that is not using the limits of the battery.
3.40*12 = END 40.80 + 2.6 = START 43.40 Beyond Limits of Battery
(Will experience heavy unbalance and High heat)
3.50*12 = END 42.00 + 2.6 = START 44.60 Limits of Battery
(May experience heavy unbalance and High heat)
3.60*12 = END 43.20 + 2.6 = START 45.80 Good
(Recommended Limits of Battery)
3.65*12 = END 43.80 + 2.6 = START 46.40 Better
3.70*12 = END 44.40 + 2.6 = START 47.00 Best
(Never experience heavy unbalance and High heat Less range)
