Eric,
Im sure you know this but once you cycle the battery 2-3 times make sure you load test it..

I don't understand the need to use a heavy 4500 mAh pack
--------------------------------------------------------------------------------

I don't understand the need for a switchglow because its heavyer than a glow wire.

Why add the extra weight, especially if you fly 3D? That's just my $0.02.

Why add all the weight of a switchglow when a glow wire is clearly ALOT lighter.

A 4500mAh battery,glow wire and 6.0V reg is lighter than the things people run on there helis these days and leaves room.A switchglow,LiFEPO4/A123 alone isn't light..

I'm afraid you missed my point. My mention of the Switchglo was only to point out that I have a power hungry setup, and I still get 6-7 flights on a 2300 A123 pack. The Switchglo also has benefits to trade for its added weight. Ask anyone who uses one and you will hear nothing but rave reviews of the Switchglo.

I contend that the heavy battery is not a benefit. It's just dead weight. Most people don't fly more than 6 flight in a day anyway, so the 2300 pack is more than sufficient. You can also recharge quickly if you want to fly more than 6 or 7 flights. Personally, I bring a spare, fully-charged A123 pack, so I don't even have to worry about bringing a charger.

The only reason I see to use a heavier battery than needed is if it helps balance the heli. Most of the time using a pack over about 2500 in the standard battery location for a model will cause a balance problem. I'm not sure if this is the case with your Raptor 90 or not, but it would be on all my helis. Like I said, this is my opinion. You and anyone else using a heavy pack can do as you like.

The biggest problem with LiIon (e.g., Relion, Duralite) is that the max charge rate is 1C. Worse yet, Duralite only warranty their packs when used with their overpriced 400mAh output charger. The Relions don't come with taps so the better chargers are even more conservative when charging a 2s pack w/o taps.

IMHO LiFePO4 is the best RX pack chemistry available today followed by LiPo.

rexxigpilot,
I didn't miss the point of "get what I have because thats what I like" or "its the latest and greatest so you gotta have it" .You must be running HV servos because thats the only power hungry servos out there.Do you know that Align DS610's pull more power than JR 8717's ,do a search..Ive been running Align DS610's for a long time now with no issues,so I know for a fact his JR 8717's will be more than fine.Your trying to tell someone that runs these batterys how there heli will balance,be too heavy or not get enough power LOL,ok man.

Your right,use what you want but don't give bad info out.

Feedback
Hey guys I do appreciate all the feedback you guys have given me. First I am gonna try that 4500Mah Li Ion pack I already have and see how that works. I may end up getting a A123 Li Fe pack after that. Every keeps talking about my flights, honestly I may fly like 4 times while I am at the field. I dont fly alot but I do fly some. I will try those packs and get back to you guys with my findings.

Thanks,
Eric

I'm getting 5 flight on my 2s 2100mAh LiPo RX pack.

A 4500mAh pack will have plenty of reserve.

Again you missed the point! Do you just like to argue and make crap up? These type of people are known as contrarians. Do a search.

FYI, A123 cells have been out for a long time now. They are not the latest, greatest. That distinction goes to the flat pack LiFePo battery.

Prove to me that the 610 is any more power hungry than an 8717 or even a BLS351. Do you have any data to back up this claim? I didn't think so. Who's giving out bad information now.

Could it be that the only reason you are so adamantly supporting the use of a HEAVY 4500 mAh pack is because that is what you use? Based on your post history shown below, It is obvious you like to give out free advice. Next time just make sure it is correct information.

I stand by my recommendation to use the A123 packs, not because that's what I use, but because that is what I found to be the best. I have used NiXX, LiIon and LiPo before. They all work. I just like the advantages of the A123 listed in my earlier post and the posts of others. "No need to argue." Don't be a "Zombie."

Sorry, those albums/songs by the Cranberries popped into my head thinking about how you like to argue so much.

It all depends on what you consider the latest and greatest. LiPo still has the highest energy density so the latest LiPos will be smaller, lighter and have manufacturer approved charge rates at 6C. Thus, if size and weight are your biggest concern the LiPo is the way to go.

If safety is your biggest concern then LiFePo4 is the way to go.

I had originally purchased a 2s A123 pack for my Vibe 50, but it was too big and heavy for my liking so I went with a 2s 2100mAh LiPo instead and have been using that for 2 years.

Now they they are available, I purchased a 2s 2100mAh Hyperion LiFePo4 RX pack to replace the 2s LiPo which I plan to install soon. I like the 4C charge rate and safety factor over LiPos.

info
Guys I didnt want this to be an arguement. When I got out of flying 4 years ago the only thing out was Lipos and I had one of these flame up on me. It was not a good situation. Since then I have gotten back into the heli world and I purchased a Li Ion 4500 battery while I was in Afghanistan for $35. Since I have that I want to try that first. If that doesnt work for me than I will look at other sourses. I had when people just argue back and forth on forums because of what they like. I dont need 11.1 volts to my servos and I am sure the Li Ion I have with 7.4 and a step down to the tail servo will work great. I will give feedback as I try this out.

Although it will work, a Lithium Ion battery is incapable of delivering the current you need for 3D.
This is the stuff that keeps me coming back. You never know what you'll hear on Open Mic Night around here. Keep 'em coming -- great stuff!

Whats your point other than you keep babbling about how heavy,unbalanced,ect.. the battery is which is BS.
Prove to me that the 610 is any more power hungry than an 8717 or even a BLS351.
What are you 6 years old?Do a search,you seem to know everything else so im sure you know how to search and read right?Im not asking you to prove anything because im not a bench racer,theres tons of proof in my youtube.

Seems you can't read so maybe a pic will help,ive used all types of batterys.
I stand by my recommendation to use the A123 packs, not because that's what I use, but because that is what I found to be the best.
I could care less what you stand by and thats good for you and nice to know whats best for YOU.Eric can use whatever he wants and if hes happy that all that matters.Its good to put options out there but for you and other bench racers (flying internet pros/stick bangers) making it sound like everyone has to fly what you/they have or they can't 3D,the heli will be all out of wack,too heavy or won't fly right is BS .

Whats the point of posting my profile info LOL?Im no pro but you can check this out too so you know how crappy I fly http://www.youtube.com/flyinhigh450 .My nitros have Fromeco,Duralite,Lipo,Nimh,Lifepo4 and Nicad batterys .

You don't need to get so defensive and attack others at 35 years old, or do you? My posting of your profile data is to show how much time you spend "babbling." Your words, I called it free advice. See how much more polite I was.
