Discharge is the amount of power the battery can 'push' out and the number shown '20C' is an multiplication of the capacity. For example* A 20C battery can discharge at 20 x 2,000mAh which is 40,000mAh or 40Amps.
This is an important number if you know your motor requires a certain power level.
In addition to this, batteries have a 'Burst' rate, which is the amount of power the battery can discharge for a short period, usually 10-20 seconds. A typical battery label may show 20-30C, this would mean a 1,000mAh battery can discharge 20,000mAh constantly or give a sudden and short 10-20 second 30,000mAh (30A) burst of power.
Tip: A higher 'C' rated battery will last longer if run at a lower 'C' rate. Example: a 30C battery run at 20C maximum will have a longer cycle life than a 20C run at 20C each flight.
Hello my name is Eli and I want to know if I can connect 5 batteries (3 cell 8400 map c30) column to obtain 15 CELL (55 volts). I also want to know if I can use them, for motor and controller 250 amps. tenx
well, you are thinking of dealing with ultra huge power...you can use them with a 250 A ESC, but it is very important to select an appropriate wire guage which is capable of handling such a power in case of extension...and then select appropriate connectors...i have heard most of the connectors are upto 70 A and going beyond them will melt them...
So I have heard that lifepo is better for obvious reasons. But i have seen that theses batteries can be charged to 4.1volts per cell. Which is really good and are way more stable and way less dangerous. But i could care less about safety. Though these batteries are heavy. its like 100 more grams for 400mah more than the 8000 3s lipo version
I have 2 of them. Great power on a H&M Maritimo 95 km/h with a NEU 1521 (1900 kv), i can use 8300 mah in 7 minutes. The boat is heavy but don't fly! The packs doens't inflate like with LIPO's after the run. Very good batteries.OB
