Default Align High-Power Li-Polymer Battery

This question is for T-Rex 600 owners.

I have the Align High-Power Li-Polymer Battery, 16C, 22,2V 4200mAh in my T-Rex 600.
My flight time is about 7 to 8 mins. This is normal flight, not 3D. Do this time sound about right??
Do anyone know if Thunder Power make a battery for the T-Rex 600?

Thank you all for your answer and time!!
This is a great site!!!

Thunder power Does make a battery for the 600. YOu can also combine 2 11.2 V 3S batteries to get the same battery. YOu just need to make the appropriate Y harness with deans connectors. Making them this way will save you from getting another charger if you haven't already bought one for that big align battery. 2ndly, you can use them for other smaller applications, and 3rdly, if you wreck your big pack, you're out the entire pack. If you wreck a cell or two in the 2X setup, you might get away with only having to replace one of the packs.

Yup, that's about right. I get about 6 minutes on my dual 11.1V packs with mild 3D. 7 to 8 in normal flight.

In my opinion, you should do as Shag said, and get 2 11.1 packs instead of a single 22.2 pack. It's a bit more work having to charge two packs for a single flight (I've got two chargers so it's no big deal for me, but not everyone does), but It's just more convenient. You can use the packs in other smaller models other than just the T-rex 600, and, as shag stated, if something happens with one of the cells, you're only out half the cost rathern than the full cost.

Here's a shot of my helicopter, in the bottom right corner you can see my 2x Electric Power 4400 mAh 12C packs connected with a series connector I made.

Multi-packs is the way to go!

Shag555 and Credence, thank you both for your answer. Looking at the cost of the one big battery is a bear. I have 4 11.1V packs in the shop just sitting there. Making the Y harness, if I can see a good picture, I can go from there.
Credence, good looking 600!!
Thank you both for your answer and help!!

FlyMike, you will love it. I fly my 600 more than my 450SE. Very easy to build too. Any question about the build of the 600, please post and we will try to answer. Have fun!!

Default RE: Align High-Power Li-Polymer Battery

Hi,

I was thinking about using my T-Rex 450 batteries in series to power a T-Rex 600. But i was thinking that my small 2100ma packs would only last a couple of minutes?? If you get 7 -8 minutes for 4400 i would probably only get 3-4 mins right? Tho the weight would be alot less?? what do you think??

It probalby wont happen. But i would love to get a 600.. Just the battery price tags are so huge!!

Also would the DX6 work OK with the 600?? Or would i need 5 point curves and all that?

Cheers.

Hi Arven,

If you have one of your t-rex battery at 11.1V and 2100ma and add another one of the same size. That will give you a total of 22.2V and 4200MA. That will you the same total as one one of my battery and will be far less than what I paid for my battery. I am looking at picking up more 11.1V 2200MA battery and build my own packs for my 600. When you do pick up a 600, you will be happy you did!
I hope this help you out! Have a great week.

Connecting in series does NOT add up amp hours.

If you had two 2200 mAh 11.1 volt packs, you could either connect them in SERIES, in which case you get 22.2 volts, but 2200 mAh.

Or, you can connect them in parrallel and get 11.1 volts, but 4400 mAh. Both voltage and amp hours don't add up together, it's one or the other.

If you had 4 2200 mAh lithium batteries, then you could make two packs that are both 11.1V 4400 mAh, then connect all 4 together to make them 22.2 volts, 4400 mAh. But now you're talking about charging 4 seperate batteries for a single flight, that's alot of work.

2200 mAh batteries, even if they were rated for true 20C discharge, would not last long on the t-rex 600. You'd end up killing the batteries since amp draw is simply too high. The helicopter hovers around 30 to 40 amps if I recall correctly, which is already nearly exceeding the batteries discharge rating, as soon as you add quick pitch changes, you're peaking 70 amps or more.

4400 mAh, really, is the bare minimum, you should actually go HIGHER. More weight, but your batteries will atleast last longer.
