sitsinhedges Posted December 2, 2012 Report Share Posted December 2, 2012 Turbo flappers don't have a specific battery do they Quote Link to comment Share on other sites More sharing options...

kody Posted December 2, 2012 Author Report Share Posted December 2, 2012 so i could use the bigger battery that i use on the magnet for the flapper 12v Quote Link to comment Share on other sites More sharing options...
yickdaz Posted December 2, 2012 Report Share Posted December 2, 2012 I'm selling some 12v 2.1ah battery's ... Cheap ;-) they are more suited for the turbo, but you can use 12v 7amp and 12v 12amp batteries if you want, but the point of the smaller battery is the weight and they last all day on a turbo so makes sence Quote Link to comment Share on other sites More sharing options...
Mr pigeon Posted December 2, 2012 Report Share Posted December 2, 2012 I use a lithium ion 12v 9.2 amph battery mate. Expensive but runs all day no problem and is a third of the weight of a 7amph normal. It comes with a green canvas case and charger from cluson engineering.

Agent36 Posted December 7, 2012 Report Share Posted December 7, 2012 I use this analogy at work for the airframe engineers, it might help here. The voltage (V) is the pressure in the tank, the more voltage the faster it will run, these motors are designed to run between 6 - 18 volts. The amp hours (amph) is the size of the tank. If you have a flapper running at 200mA from a 12V 7AmpH battery it will last for 35 hours. 7 A / 200mA per hour = 35. A 12v 1.5 AmpH will last 7.30 hours. I hope this helps!!

Mr Rizzini Posted December 7, 2012 Report Share Posted December 7, 2012 I use a 12v 3amph and it hasn't run out on a long days shootng yet, I got mine from AA Decoys Quote Link to comment Share on other sites More sharing options...
fenboy Posted December 7, 2012 Report Share Posted December 7, 2012 If the battery has had it , could be that your using the wrong type of charger. for the 1.2 amp/hr battery a charger giving 300ma will be plenty and that will fully charge it in around 4-5 hrs if you are using a bigger charger then its likely you have fried the battery.

I use my old motorbike trickle charger and it seems to charge my battery in an hour or so and has been working for about 9 months, I may not be using its full charge as its a 3amp/h Quote Link to comment Share on other sites More sharing options...
