Iam in the market for new ECUbatteries and Iam wondering what is the best battery for price and performance. Iwould prefer non-combustible.

Iam running Jet Cat P-120 kero starts (Non-SE, older versions) ECU 5.0 & 6.0

In the past Ihave run Duralite Li-Ion (Powermax start only) and Duralite Li-Manganese. I've been very satisfied with both batteries, just not with the sticker price.

What do you use?

Cheers,

In my JetCat's (P60 and P70) I have used 2cell 4800Mah LiPo. Both Kero start and Powermax start. I have gotten over 15 starts/runs/cool down cycles before having to recharge on my P70.

But I needed nose weight in my plane and the LiPo added the extra weight needed perfectly.

You'll be hard-pressed to beat a 3-cell A123 in either a 2300 or 4600 Mah configuration. I just made 2 4600 Mah ECU batteries for my BARF and Ultra Bandit.

Here's a little A123 FAQ I had put together a while ago.

The facility to charge A123's at very high Amps on the field and that they do not need ballancing every time you charge makes them very hard to beat in my opinion, I have never found out how many starts and cool downs I get out ot them as I recharge after three flights, takes about 10mins, or just a bit longer than filling the tank or BSing the guys.

Does the Jet Cat ECU require any modifications to use toe A123 batteries?

Thanks for all the input and votes so far!

yes send it back to jetcat for the update. i think it is 25 dollars now. i did it to all three of mine. Without he update it is like a crapshoot. you can get plenty of great starts and then "poof:" you can blow the mother board..Bob states it can cause over 300 dollars in damage AND ruin your weekend

Oh wow! Ok, well worth the update then!

Thanks for the heads up.

Is this a lithium chemistry?

A123 3 cell for the Jetcat ECU not a 2 CELL just to confirm that is the right number of Cell A123.

Just a bit more, you can not reliably use a 3 cell A123 with a standard JetCat ECU it will eventually let out the magic smoke, JetCat Germany will upgrade to use A123's free of charge if you send it to them, but can not do an old P80 ECU, don't ask me why I don't know, JetCat US will modify any ECU for a small charge.

I assume this is a FlighPower Green packaged EVO LiPo 2 cell battery, if so a 2 cell should be OK unless the ECU can not take 8.4volts fresh off the charger, check the settings on you ECU to see if it will take 8 cell Nicd or Nimh.

THANKS GUYS

I solve my problems about ecu battery older p-80
I tried using a flight power7.4 volts evo lite v2 Lipo 20c 50 amps continous and 30c 75 amp max burst, that battery works very good,

i had had problems starting my p-80 (bad ecu readings,  like temperature at the moment  to start, glow plug damage, abort starts and meny others failures), and when i decided to change my battery everything return to normal, i used a lipo 7.4 and  i'm  happy.

the  problem was my old NI MH  battery, it didn't work properly, ecu was creasy.

thanks every body for help me
