Its been a while since i last posted.. and boy has this hobby changed in the last three years. I used to be a nitro faithful and since my break from heli's i have brought a trex 500.. a great little heli.. no going back to the oilers now
I bought a trex 600e yesterday which is going to be test flown for a bit and then eventually end up in a scale. I already have 6s1p 2x 2500mah Flight Power evo 25's, so would it be ok to parallel these packs to make 5000mah.
Anybody got this set up?
Thanks

You can run them in parallel if you do it correctly. You have to wire the balance cables in parallel so it will balance properly as a 6s2p 5000 pack. Make sure that all cells are at the same voltage (storage voltage of 3.7 to 3.8v is best) level before connecting the parallel wiring.

Hi Ben
Thanks for your reply
I am happy with the parallel leads but how do you make sure the balance leads are in parallel?
I am happy to charge each pack seperately so balances and voltages should be matched. Will this be ok?

i dont wanna ever tap into my balance plugs. too much to mess up if your not careful.

But if you run those two packs like they do on the 500, then all you're doing is creating a 12s 2500 mah battery. Not that effective on a T-Rex 600. Just go out and spend the money on a 6s Flight Power battery. A lot less complicated if you ask me.

Actually, "high voltage" setups are common for the 600E. This is done to improve the efficiency. Watt-hours are watt-hours. Using lower current with higher voltage equals lower power loss due to resistance. Of course the ESC and motor would need replacing.

I think flight power 6s1p 25c 22.2v 2500mah in parallel makes 6s2p 22.2v 5000mah in my books, with no loss of performance or weight gain over a 5000mah pack. Not complicated just connect the parallel leads
I have no problems spending the money on batterys but this ship is going to become a scale, on A123 batterys. Just thought i'd use my t-rex 500 batterys for the initail test flights.
Thanks for the advice guys.. run ryder rocks

Just for the record:
2 x 11.1 2500:
Parallel: 11.1V 5000mAh Series: 22.2V 2500mAh

Yeah but what I'm saying is that even though many people run those high voltage setups, 2500 mah would not be enough in a series. But if they are wired in parallel correctly then yes that would be the same as a 6s 1p 5000 battery.

i acutully use that setup for 3 12s setups i have,2 6s2500 fp in series.works awesome and is light and still get decent run times.
12s all the way the effency goes up big time and obviously so do the run times and of course the power is insane.the motor and essc run alot cooler also.
i see no reason 2 2500 6s packs in parrelel would't work just fine.
I just completed my third 12s heli. trex 600 e with the new scorpion 560 kv motor.all i can say is awesome.

Interesting for sure. Any chance of posting an FDR with this setup. Or at least average amps and run times. Head speed you are running also would be nice. Thanks.

Quite safe and efficient way to run both helis and save money. The one drawback is it will take you forever to charge both batteries to get that second flight on the 600E since you can only charge at the rate of each battery.

I use 2 flight power 5s 3700mah in series(for 10s 3700mah)and they work great. I charge them in parallel at 7.4ah (1c) with no problems. I periodically check the cells with a multi-meter and they match almost perfectly. I think you will be just fine using your 2 6s in parallel!

My question is what is the average amp draw on 12S and what generic kind of flight times can you really get with a 12S 2500mah battery in a trex600. Still would love to see an FDR on 12S.

What I really like about the setup using either series or parralle is that there is no need to purchase new batteries to fly the 600e right away if you already have a 500. He can run the parralle setup with the stock motor, esc as well. Then when he wants to fly like his hair is on fire, change to series. Centuryman sold me on that because the setups are so versitle.

just need a second charger
Which cost more than a second battery. I was under the impression he was trying to save money (or at least spend the money in batteries as per his post)
As for 2500mAH 6S in series, you may think it makes for a good idea for a 12S setup but your current draw will be VERY limited. You have to be careful.
