Omg!!! Someone please simplify battery options for my ax10!!!!!!!

You can calculate the amperage output of a battery by
Using the "C" value. Example: a 2200 mah 20c battery will e able to handle a draw of 88 amps. Here how it works. 2200 mah equals 2.2 amp/ hours, so take 2.2 and multiply it by the "C" rating of 20. Now if you were to draw 88 amps from this battery it would only last 1.5 minutes haha.. So seeing as most get well over an hour out of these pack you can figure your not drawing anything near that amperage.

So not to hijack but the OP has asked the same questions I have. Will ONE of these LIPO 2s 20c-30c be enough for the stock ax10?? Will it give similar run times to say a 6 cell NIMH 2000mah? Thanks.

Capacity is capacity, doesn't matter the chemistry of the battery. However, Lipo is so much smaller and lighter that you will generally see a longer run time. My 1300 Mah 30C 2s Sky lipo gets about 40ish minute run times and I had a fresh 1500 Mah NiMH that was lucky to get 30 minutes.

I've had good luck with Sky lipos from Hobby Partz. I have all 30C 2s packs and they balance charge pretty good everytime. I only charge @ 1C.

I asked many of the same questions only a few months ago, but I made the switch and never looked back.

I know capacity is capacity but lipo is able to give all of its capacity at near full voltage. After 1800 of the 2000 mah have been used out of the batteries talked about above, the lipo will still be 7volts or more.. The 7.2v NiMh pack will likely be below 6 volts maybe even below 5.

What happens is that as voltage drops, the amperage draw goes up. Most cheap Nimh packs cant put out high amps (I say cheap packs because there are Nimh packs out there that match lipos in performance). As you draw big amps from a pack, it's capacity is soon drained. This is why you see a difference between a 2000 mah lipo and a 2000 mah NiMh pack.

I have a couple of 3S 1300mAh Elite packs from CBP. Awesome batts. Good punch. If the AE2 can handle 3S, I'd recommend those. Can't beat the price either. On my Holmes TorqueMaster BRXL and a 35T Integy, I get about an hours worth of run time. "C" ratings are discharge ratings. You're going to need more of a guru to chime in on this one. I'm still a noob. Myself, I don't buy anything less than 35C.

Well I finally figured out where to look to see if the ESC is an AE-1 or an AE-2. Manual says AE-1 so i took the car out and looked at the ESC and it IS A AE-2 model ESC. Will it hold a 3S?

I use all Turnigy and Zippy lipos from Hobby King in Hong Kong. Super cheap and have been awesome for me. My LHS sells the same ones for 100% markup but it's still cheap.. I ran 2200 mAH 2cell lipos on my ax10 and got nearly 2 hours of crawling. Atleast an hour and 15 with a heavy throttle finger and lots of hill climbs. I switched to 1300 mAh 2 cells just to save space and c
Got over 40 minutes out of those.. My LHS charged $13 for one of these.
"C" value does make a difference in punch. Think of it as voltage under load.. When your 1 hour into your lipo pack and you punch the throttle, a 40c lipo will be MUCH stronger than a 20 c lipo .. I know with a crawler it's less noticeable.. But I'm no expect comp guy and I notice it.

Im liking the 2200mah 2 cell run time but what about a 3s version. and I know im using a servo/battery plate from either axial or CKCRC. I have heard bad things on CKCRC also. Are they not a good company to work with. However the batteries and charger are not coming from them just maybe some other stuff.

 

[Big Daddy]

I'd get your battery plate or at least the dimensions of it before you get batteries. A 2200 seems pretty big for axle mount.
According to axial website you can run 3s and I know some people have without problems, but some people have burned up the ESC on 3s.

I've never used CKCRC... so I won't comment on them.

True, I forgot the new ae-2 has lipo cut off, So as these guys said. Do your self a favor and just buy a lipo setup. "thumbsup"

Again, you don't need to worry about c ratings for what you're doing. Look for 1000-1300 mah 2s packs

Here you go, cheap and already has a deans connector. I've ran these batteries and they're pretty decent
GForce 30C 1300mAh 2S 7.4V LiPO

So if I went this route would I need two of these batteries?
I'd like to get about an hour of run time.

And would my charger work for that battery? I have a "pro peak" Quattro plus output, 1~4 cell lipo charger. Input voltage: 100-240V AC/11~15V DC.

I would buy at least two, but if you can afford more get 3 or 4. You won't be upset having too many batteries I promise. I am not familiar with that charger but I don't see any reason it wouldn't work.

These batteries come with a deans style connector so you will need to add a man deans plug to your charger and esc if you haven't already done that.

Yeah I already have Deans connectors.
I just ordered one for now to see how it works for my setup, if I like it I'll go back and order more.
