I want a new motor and it will require 11.1v and I cant find a 11.1v 2s my esc is rated for LiPo 2s. It says max discharge 30 amps will 3s kill it even with esc fan?
If your ESC is not rated for 3s, it will likely kill it as it will exceed the voltage limit. The current is a separate capacity and relates to the draw of the motor. Make sure you are 3s capable.
You cant find an 11.1v 2s because 11.1v is 3s (3.7 x 3 = 11.1v). The cell rating is directly related to posted nominal voltage. Your ESC doesn't see individual cells, and if it can run on multiple cell configurations, it figures out cell count based on input voltage.

thanks any suggestions on 11.1v lips batteries and esc capable of handling 3s
Yes, it will kill it. You cant find an 11.1v 2s because 11.1v is 3s (3.7 x 3 = 11.1v). The cell rating is directly related to posted nominal voltage. Your ESC
ESC
An electronic speed control (ESC) is an electronic circuit that controls and regulates the speed of an electric motor. It may also provide reversing of the motor and dynamic braking. Miniature electronic speed controls are used in electrically powered radio controlled models.

This is sometimes why you will hear people talk about a "2S" battery pack - it means that there are 2 cells in Series. So a two-cell (2S) pack is 7.4V, a three-cell (3S) pack is 11.1V, and so on.
Each LiPo cell is rated at 3.7v so a 2S LiPo means it's a 2 cell battery and 7.4v, a 3S is 11.1v, 4S is 14.8v and 6S is 22.2v. For more info tune into our video below as RC Expert Vas explains the basics of Milliamps, C ratings, cell sizes & more. Metro Hobbies. 10.8K subscribers.
For a 3S battery, once you start seeing voltages in single digits (3.33V/cell is 10V, below that), it's time to land as a quick reference point - although you can set more precise values of around 10.6V as the warning point through telemetry at a transmitter and/or OSD on an FPV display.

Many of the 64 mm 3S park flyer jets come with a 30-amp ESC. The stock power system measures approximately 27 to 28 amps at full throttle. Going up to 4S means the amps will be approximately 36 to 38, so the possibility of burning out the stock ESC becomes a concern.
The difference in efficiency is not linear, you will get longer than 33% more run time on 3S of the same capacity compared to 2S, given that you re-gear the 3S appropriately such that both setups run comparable motor temps for respective FDR... both will have similar top speed, but 3S will offer faster acceleration.
It all depends on what the motor and ESC will handle. Going to 3 from 2 cells adds 50% more voltage. That means more speed and more amps. If you running a 3 cell now, and the motor or ESC hasn't given up the smoke, I say keep doing it.
If you limit max throttle below the smoke point, you will be fine. If you are planning on running full throttle on 6S, you will most likely see the smoke monster! The 3S motors I ran on 6S (Sunnysky x2212 kv980) ran fine at 4S rating without much heat.
Discharged - the voltage of a discharged LiPo cell is 3.00V, and discharging below this will definitely damage the cell. Because the battery shown has a 3S arrangement, it is marked with its nominal voltage of 11.1V (3.70V*3 cells). A fully charged 3S pack is 12.60V and a fully discharged 3S pack is 9.00V.
You should never store a fully-charged LiPo battery. Instead, it should be brought down to “storage voltage”, which is 3.8 to 3.85 volts per cell. There are a few ways you can achieve this. If the LiPo cells are currently under 3.8-volts then you can charge them up to this level.
That means that that ESC can handle a maximum 35 amps draw, at a maximum of 3S, or 11.1 volt (a fully charged LiPo is actually around 12.6 volts, but drops as you use it).
A 3s lipo is 11.1v and the xl-5 is rated for 8.4 max. Yes but keep in mind the XL-5 ESC has no LVC so you will need an external LVC or LVA to protect any lipo pack you may use. Yes but keep in mind the XL-5 ESC has no LVC so you will need an external LVC or LVA to protect any lipo pack you may use.
The E-Maxx and Savage 550's are meant to be run on 14.4 or more volts. Running that same motor on 11.1V will not hurt it in any way. In fact running that motor on 3S will be slower than what you would see out of a stock 12T titan as you're not giving it the voltage it needs to spin.
3s is a pretty standard voltage for crawlers. And "crawler" brushed motors are generally fine with the higher voltage (they are slow motors to start with so you aren't pushing the limits).

If my esc is rated 2s will 3s kill it
