I was wondering who is using A123 12S 2P battery packs either through TanicPacks or built their own from Dewalt battery packs. I am trying to decide if I want to invest money on these packs for a Logo 700 that I will be building. If you are using these packs, can you please post info on your ship and how many minutes of flying you are getting from these packs.

Thanks,

Joe

I have a 12s2p pack from Brian at Tanic in my Maxi Joker II (Schulze / Pletti)

It's an awesome pack...feels indestructible, pour the coals to it and charge fast.

Flight time is 8 minutes comfy.

I'm pretty light though...camera is only a G9.

If weight is not absolutely paramount then you will be well served by A123's.

And Brian at Tanic is an A+ person to deal with...highly recommended.

When in doubt...auto out

They work great. depends on what you're carrying, but I can haul a 5d and fly for 7:30 minutes ( with plenty of reserve).

Rhett..... I can't fly, but the Profi sure can.

For photo I run selfmade dewalt A123 10S2P packs in a modified Vario silence swinging 720 Vario blades hauling canon 40D. 5 mins with 1.5-2 min reserve is my pack limit. Can probably push them more but I prefer not to. Not long by lipo standards but time in the air is relative to each pilot.

I also run 10S2P TrueRC packs for video which are great bang for buck AP lipo's.

I wish the A123's had more capacity. The safety factor was at the top of my list when I chose them and charging time second.

... But honey it was only $$$

I have Tanic 12s2P on a Maxi Joker 2 and loads of gear, tot AUW is 10kg, and flightimes around 8 minutes ( i have longer blades and slower rpm)

I would NEVER consider going back to lipos

I must admit though that Brian havent answered my mails for the past 6 months now, but he used to be a+ on that side, so i dont know whats going on over there now...
Probably the "dont reply to certain customers" flue like several others suffer from these days

But the batteries rocks!

Question....

The A123's that come out of DeWalt 36volt power tool packs... Are they the 18650 cells... or the 26650's?

A123 sells their 6 cell "Developer Kit" for $129.00... or 2 for $220.00
This looks like a pretty good way to go, particularly if these are higher capacity than what comes from DeWalt.

Inquiring minds wanna know....

Whats the difference between those two?

I think 440$ for 24 cells sounds expensive when a ready built 12s 2p pack costs little over 500$, or?

Checked it up, 26650's are the 2300mah cells and the ones we use for power packs, that also means that the Dewalt are the same as 26650...

Whats the weight diff between lipos and A123 for the equivalent power voltage level ? I'm using 10S 4350 mah lipos, I'm paying $130 for 5S 4350 mah each which is $260 for 10S. Just curious if A123's are in my future ???

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

If i remember correctly, a 10s lipo pack weighs around 1.3kg, and my 12s 2p A123 weighs around 1,9 kg

Gyro, remember, i got 12s 2p, which means a total of 24 cells (43.8v - 4600mah)

Is there a special way of charging these packs using a TP-1010 charger?
I have the new firmware installed that supports these batteries. Also, do you need to balance these packs? I also heard that these packs can be charged crazy fast. Is this true?

Charging a 10S pack will take 15 to 20 min at 8.5A. They really dont need balanced, maybe with every other charge. Until this week I was using the standard Dewalt charger. I would pull the charging module from the pack (only connected by 2 balancing tabs and a deans connector) and fly with the pack still in the Dewalt case. Then connect the charging module and drop it in the Dewalt charger.
I have been buying the full 10S 36v packs (new) on Ebay for about $110 shipped (you can get a better deal if you wait) That is much less than what you pay from anybody else.
In over 2 years, I have had only 2 cells go bad, I just cut that cell out of the pack and replace the one cell. I tend to run these batteries bone dry.
I will be trying out some Truerc packs, but A123's are great!!!

not sure on the TP-1010

I'm only getting 6.5 minutes on 10S1P but I'm not sure if my Tonic-x 800kv motor is just less efficient.

what motors are you guys running?

I fly 8mins easy in my joker2. 15minute charge time direct from a Mastech powersupply. That's with 12s2p 4600's from Brian. I have found him A1 to deal with.

Same as Fergus.
I havent balanced my packs for the last 30 or 40 times, dont notice anything, you can do virtually almost what you like to them, theyre almost indestructible...

Correct me if I am wrong but aren't LIPO packs good for around 125-150 charges? Which means you can fly three times a week and it will last you around one year. Compare that to the A123 packs that can be charged up to 1000 times. Really sounds like you will get your moneys worth going this route.
