I have a 1s, 2s, and 3s lipos. What is the lowest PER CELL that the voltage can go?
When i google it, i get:
3.7V is the average voltage; LiPo can be charged up to
4.20V and discharged down to
3.0V per cell, any lower or higher in voltage and the cell will almost certainly be damaged and will become unstable which can be very dangerous.
But when i search on forums, some people say 3.7V, some say 3.8V, but here we are with 3.0V...
Don't confuse minimum voltage with minimum storage voltage. All LiPo batteries should be kept at a 60% storage voltage when not in use. If you use a proper charger, the end voltage should already be set. It is true that you do not want to run your batteries lower than 3.0v per cell as that will induce damage to the cell. That's why balancing is so important with LiPo batteries. One cell could be at 3.2v and the other at 2.8v and you wouldn't know it till one of the cells totally craps out.
It's best to never run you batteries down below 3.2 volts per cell. In racing, we rarely run them down below 3.5v.
