Zenoah G62 battery size
Hi all
Would a 2500 mah A123 battery with IBEC be OK with a zenoah G62 with electronic ignition in a TF Giant Corsair? would be driving 7 servos total and electric retracts.
Not sure if I should go larger or just add another battery
Weight is not an issue
Thanks
Larry

I would add another battery and a battery sharing device such as a Smart fly Batt share. I think the load on a single 2500 pack powering Ignition , servos and retracts would be borderline . 2 packs with a sharing device worked well for me in several warbirds . Be sure to check the capacity remaining in the A123 packs after a 10 minute flight so you can judge how much power the system has used per flight. Use that to calculate how many flight you can get before recharging . BTW with A123 packs I never use more than 50% of the capacity before recharging . This gives a good safety margin.
I would also verify the IBEC output voltage to the ignition and be sure that the Ignition can accept it . Some IBECs regulate the output and some don't. Some older C&H ignitions don't like 6.6v either.

I would think 2500 is more than enough, but, that is not the concern.
I would isolate the retracts most of all. One landing and all appears good but a small problem occurs. Next flight,Bam, plane crash, loss of power due to retracts constant draw until drained. I like electric retracts, they just need to be done right.
As far as the IBEC what are it's specs and what ignition is it powering?
Radio and servos, are you HV or is the battery going to be regulated?
You have given very little info, specifics are needed?

Here's a better way that requires no thinking or guessing. Peak charge your battery. Fly for ten minutes. Write down the ma charged. Do this six times. Add the six numbers. That’s the number of ma you have consumed in one hour, or the number of mah. Double or triple that value for a safety factor. That’s the minimum size battery you should use if you are going to fly for one hour. Increase the battery size if you plan on flying more each day. Dan.

Thanks all for the info-
I think I will avoid the IBEC and use one battery for receiver/servos and one battery for ignition. I am looking into isolation of the retracts if that is feasible (not sure how yet as they pull off of the receiver) but will check it out
Thanks again-
