Turnigy 1800mAh 4S 30C Lipo Pack

Hello RCFlihgt13! Constant discharge is 30Cx1800mah. Always use the following formula: Use the "C" rating and multiply it by the capacity (mah) 30x1.8 amps Where 30 is the constant "C" rating and 1.8amps is equal to 1800 milliamps (Capacity) 1800milliamps looks like this expression with the decimal****-1800.00 Move your decimal 3 places to the left for the amp rating of the battery and you have this****- 1.8 So now you see that milliamps is 1/1000th that of an amp. To prove it mathematically, d

1800 MAH times 30 C = 54 Amps. The formula is simple. Take your MAH X C = Total Constant Amps IE 1800X30=54. Hope this helps.

hi there can put out continuously 54amps and for a burst of 10 seconds 72 amps you get this ratting by multiplying the 1800mah by the c ratting of the battery in this case it 30c continuously or 40c for 10 seconds, which is 1800 milliamp hours multiplied by 30 which = 54000 miliamps and because a miliamp is one thousand of an amp you knock of the last 3 zeros and you are left with the amps rating for the pack. the 10 second 40c rating is 1800mah multiplied by 40 which gives you a rating of 72000

The formula to figure out output is the C rating multiplied by the mAh. So you would be able to get 30C x 1800mAh/1000 so these packs are capable of supplying 54Amps. Dw

30C
30 Amps constant, the higher this # the better the pack, the more it will put out before tripping out, and of course, the more expensive

1.8x30= 54 Amps

Supposedly they can put out 54 amps constant (1.8x30) but at that there is a relatively high voltage drop so it would be better to try and pull less than 50 out of this pack to get the best power output.

the math is 1800mah = 1.8amps x 30c = 54amp remember 1000mah=1amp convert it to amps then x by the C rating gives you constant draw

hi mate just times it's c rating by amps. in this case 40x1.8 amp this gives you 72 amps constant. hope this helps.

You can expect around 54Amps continous with this pack.

I have one that will 45 amps for 30 sec , the pack does not heat up with that load. - maybe I have an exceptionally good pack ?

1.8Ah * 30 = 54A (constant) 1.8Ah * 40 = 72A (burst)

54amp in theory, in practice it is always 10 to 20 less

 Niels-Erik 40 points

1800 *30 = 54000 =54 Amp

1,8 x 30 = 54

30C means 30*1.8A = 54A constant discharge
