How to know a battery (FOR REFERENCE)
VOLTAGE-nominal voltage (3.7v)
CAPACITY-4500mah: this battery will give 4.5amps of current for one hour(theoretically)
WEIGHT-about 200 grams (package): A battery has a huge effect on the planes power to weight ratio.
Two extra ounces will make a big difference in your planes performance. Jets need a better than 1 to 1 power to weight ratio to perform like a jet.
PHYSICAL SIZE-26650 (mm)standard
BATTERY CONNECTOR-try to find a battery connector you like and stick to it. (not include)
DISCHARGE-20C: the “C” rating is an multiplication of the capacity.
The millamp hours divided by 1000, times the C rating, equals the maximum continuous discharge amperage the battery is capable of sustaining.
→ mah/1000 x C= Amps, so 4500mah/1000 x 20C= 90Amps.
CHARGING RATE-a slower charge is always better for the health of your battery.
