Default Need Help Finding 3s Life ECU Batteries.....

I just purchased my second turbine (I'm hooked). I need a 3s Life battery (around 3000 mah) for the ECU and have found very few choices. The first plane I bought came with a Aga-Power 3s Life and I've heard good things about these batts. I can't find a place to purchase them. I've seen the batteries that Kingtech sells on their website and only a few other choices. It seems that a 3s is hard to find. Suggestions please.

Thanks

I did the same thing looking all over for the 3 cell LiFe's when I bought my first KingTech turbine. IMHO, the one KingTech sells is hard to beat. It's also an LiFe so it's prismatic cells vs. the hard cell A123's which come from various suppliers. You get three 2500mAh A123's stuck together and your mounting location/options are more restricted tha with the flat prismatic cells.

I actually do prefer the genuine A123's for flight packs and such, but I don't think they're necessary for an ECU pack.

I was also looking to have a spare ECU 3s Life and like you found the choices limited and the prices to be more than they should be for that type of pack. I found a pack from HK (yeah I know). I have found that the reality is that once a pack has gone through ten or more cycles and continues to perform, it usually lasts just as long as any other name brand pack will.

I've had great success with the 3S Lipo from Spektrum. Hundreds of flights with no issues. Highly recommend. Available directly from Horizon Hobby or your nearest Hobby shop/Dealer.

+4 Been using ED A123 for years. Never a fail, outstanding, friendly, and fast, service, great products. Custom builds if you need them. Give them a try.

I love the extra long balance and charge cables pre installed! Makes charging while the battery is in the jet a breeze.

I saw that one. I've ordered several batteries from them with good results. Is 2300-2500 mah big enough? I only fly 2 (3 times max) per day.

This is for a K60. The plane has electric brakes, I planned on running the brakes off the ECU battery. Would 2300-2500 mah be big enough?

I use a 2500 mAH aA123 with a K210 and get 3 8 minute flights with no problems .... I am not familiar with E-Brakes battery consumption figures, so i would not know if a 2500 mAH will be enough for ECU and Brakes.

I wound up buying the 3800 mah from Kingtech. I was hoping to find something a little smaller and lighter, but all of the other choices are square or triangular. I need a slim battery for the space I have.
At least I have more choices now................Thanks
