batteries or brushless
 

i need 2 know if i should buy 4 ib 4200 and a mrc 977 or a brushless setup right now i have epic 3000 and radioshack charger wat do u all think:032:

The ib 4200 would make an improvement. I like lipo more right off though.

Go with the batteries to start. Without good batteries, a bushless system will not run that well anyway. Good batteries are base of any good brushless setup.

I wouldn't get a 977...

Ditto... the 4200s sound like a good idea, but check out some other chargers.

Maybe I just don't like MRC chargers, but they have really had some duds so I would never buy one. Especially ever since they that one (907 maybe?) as "lipo charger" that was NOT designed to properly charge them, adn was even dangerous to use... bad taste in the mouth. :020:

Lots of chargers to choose from.....

I think you might be thinking of the 977...It was originally called the 969 and then they changed the name and a little software and called it a 977. The 959's were good little chargers, but no screen, etc...The 989 is a VERY nice charger. Kinda pricey though...

IMO, i would stay far away from the 977!!! i had nothing but problems with that charger unless i charged at a very low amp, like 3amps, or it did well with my rx packs. You could go with a triton, or duratrax charger. As for batts, you could go with gp3300's. they are suppose to pack a good punch. IB3800's are also good. IB4200's? Not sure, people say different things about them. I loved my IB3800's though, i still run two 7cells that i have had for a long time with no issues what so ever! Otherwise, go lipo right from the start!

I keep reading that those 4200's may shorten and there is no warranty on them. (that's not really advertisement, right?)

if u go with lipos what does it really improve?just the run time?and are they really hard to maintain ?they said u need to watch them while charging..im thinkin about the a123 batts but the highest cells they have is 4200s 2s2p.with that power u think it can handle a savage?or im gonna need to run 2 of them ?ive read that the a123 batts are easy to charge no need to watch them while charging..so now im thinkin of getting into lipo also..but id like to know more about it too .

You can always do a search on this forum to find out more about lipos.

i need a dual charger @ 5 amps or two chargers under $50 each with some nice feachers like the 977 wat do u got in mind i was gonna get the ice but to pricey also what about these batts http://www.maxamps.com/index.html?lmd=38968.470081 i lke the price but i dont wont to damage it some how

Go for something like the Multiplex Mike has.

i need 2 channels so i cant over charge 1 battery when i charge two at once on a y harnis

Mike has one on the store than can do more than one pack.

If you balance both packs while charging, it should prevent that making it safe to charge both in series.

i read some info on lipos and i think i will get the ones i posted a link to earler about but i need a good charger for them under $120 and wat amp should i charge at i want at least 5 amp capible charger and will the bateries be able to handle 7 feet of air

i think the ice charger is the most affordale for lipos but idk how good is it..are u buyin the 6000mah or 8000mah?

I have had good luck with my ice. It only does 4s at 8a maxx. It does 1c maxx on charge amp to.

I can recomend the ICE... I have been using it for a couple years and it works great IMO. I actually have two of them.

i dont want ice it can only charge 10 cells at once so i found this Hyperion EOS7i Charger on max amps it sounds good wat do u all think http://www.maxamps.com/index.html?lmd=38968.470081

I like my 7i a lot, especially when coupled with the LBA6 or LBA10 (newer model) balancer. It can handle up to 5s lipo or 25 NiCD/NiMH cells, and even charges lead-acid batts. Max charge current is 7amps. Obviously, the balancer is only needed with lipos. A couple of things to note about the 7i:

- It has a 120w limit. This means that the battery voltage X the charge current will not go higher than 120. So, you can charge a 4s pack at 7A, but a 5s pack at "only" 5.7A (5s X 4.2v/cell X 5.7amps = 120watts).

- You'll need a 12v DC power supply capable of at least 150 watts (~13 amps).

- I recommend to shorten the input leads. They are about 5 feet long and not really big enough (gauge) for that length IMO. Shorten to about 1-2 feet.

thx for the help 4200 shv and Hyperion EOS7i is wat i will get

your not goin lipo anymore?have u searched on the trinity 4600s or venom 4600?

i have the EOS 7i, the only thing i don't like, it'll only do my 3s to 4amps, not more than that though. I got the 989, still waiting to try it. But i like my Hyperion, easy to use and does a good charge.'
BrianG-a bit off topic, and sorry for the hijack, but you can charge your 4s at 7amps with no probs on your EOS 7i?

why cant it charge higher than 4 amps can i go 5 amps on 4200 4 at a time and im not goin lipo because i dont know enough about them yet and all the problems about them

Never have figured that out. It's rated to 7amps. Brian G and myself have been trying for awhile with no resolution. It may be the charger. I have the 989 now, yet to be used, but will tonight to see if it'll do my batts in series. I love lipo!

I've never tried to charge 4s at 7A. I got one 2s2p pack and ran it for several cycles, and then later got another 2s2p pack. Since they don't have the same number of cycles through them, I don't charge them together. Besides 2s2p is only 7.4v at 5.8Ah. I've heard you can charge emolis at more than 1c, but I'd rather not.

However, I HAVE charged my 14 cell GP3300 pack at as close to 7A as the charger will go before it hit the 120w limit with no problems.

Ah, i see. Well, as you know, i tried the 989 last night. It did my 5s no probs at 6amps.

I thought you had the 8000 mah packs. It wouldn't do 8amps charge or haven't tried.

I haven't tried as it was my first attempt to charge in series on the 989. But it worked great at 6amps so far. only took 1.5 hours. My 3s alone on the Hyperion on 4amps took 2.5 hours or more. But now i can both packs and love this thing! I kept the Hyperion though, saving it to charge my girls NiMh's and the rx packs for the Jato's. Although, i may try the power supply that came with the 989 with my hyperion and see if it was actually the charger or the power supply. I wouldn't think it's the PS though, the output was reading 12.36-12.48v going to the charger though.

do i need a power supply for the hyperion if so wat do you recomed

Yes, you need a power supply....see the hyperion thread i started, it may also be on the LBA6 balancer thread too

what power supply should i use for this charger now that i have the charger

Any power supply that outputs a steady 12v DC and capable of at least 15 amps. If you're not afraid of a little modding, you can save a few bucks by modding a PC power supply. Check out this thread.
