How important is C rating on LiPo?
The C rating for a LiPo battery, quite simply, refers to the capacity of energy the battery can safely discharge, represented as a multiple of its overall capacity. A battery that has a higher C rating delivers more energy, and that means higher performance.
Can you run Lipos in parallel?
There are two methods to connect two LiPo batteries: parallel and series. Parallel maintains the same voltage but doubles endurance; series doubles the voltage but the endurance remains the same as having one battery. It’s easy to connect two LiPo batteries.
Does C rating increase in series?
For series cells the mAh capacity of the battery is the same as each cell and the C rating does not change.
How do you connect 3 LiPo batteries in parallel?
When connecting batteries in parallel, the negative terminal of one battery is connected to the negative terminal of the next and so on through the string of batteries. The same is done with positive terminals, i.e. the positive terminal of one battery to the positive terminal of the next.
Does C rating increase in parallel?
The C-rating does not change. It doesn’t change actually, effectively, of each battery, of the combined batteries or in any other way. It stays the same. Also parallel batteries do NOT need to be “exactly matched”.
What does 30C mean on Lipo battery?
C-rating is an indicator for the nominal discharge rate a lipo can provide. A 30C 5000mAh can provide a continous current of 150 amps. A 50C 5000mAh can provide a continous current of 250 amps. So if you have a 100 amps power sytem both lipo’s will discharge at the same rate.
Will a higher C rating better?
A higher C rated battery in the vast majority of setups will be best suited. Not only does a higher C rating provide better performance but it also provides higher reliability for ESC’s.
What is the C rating of a LiPo battery?
Consider a LiPo battery pack has a specified maximum continuous discharge C rating of 50C and a capacity of 3000mAh. Do not confuse the C ratings of the LiPo, there can be a continuous C rating and a Maximum Peak C Rating. We only want to use a continuous C rating.
What factors affect the C-rating of a LiPo battery?
The following factors affects the C-rating of a LiPo battery: internal resistance of the cells – chemicals, battery construction, age etc… The biggest factor is usually internal resistance (IR), it limits the max current output of a LiPo battery.
What is the maximum current draw from a LiPo battery?
For example, if you have a 3S 1000mah 20C LiPo battery, the safe maximum current draw would be 1000ma x 20C = 20A. You might wonder, can I draw more amperage than the above figure (i.e. higher the 20A given in the example)?
How many amps can you pull from a 5000mAh 20c Lipo?
Now, simply multiply the capacity in amp hours by the packs C rating (in this case, 20C). Using this calculation, you can see we can safely pull up to 100amps continuously from our 5000mAh 20C LiPo without doing any damage.
