RX8 on fire

[scarletboa]

i've seen, used and even own turnigy nano-tech batteries and i can say that the batteries are not the problem. of all my batteries, including my expensive neu-energy batteries, my nano-techs have the least voltage drop and the most punch. also, even in my most demanding setup that has heated and puffed some of my 30c batteries, my nano-tech battery was only luke-warm and solid as a rock. by the way, mine are only 5000mah and they are more than sufficient.

the batteries are not the problem. it could be anything else though such as a loose solder post or maybe a faulty component. i've had a MMM fail in less than 5 minutes due to a faulty part and i have MMMs with over a year of heavy use and a couple hundred runs on each.

edit: also, you mention that you recommend SMC batteries. i have a pair of their 9000mah 28c+ packs and they are some of my weakest packs. my turnigy 30c 5200mah packs have more punch and run cooler. i was pretty skeptical of turnigy batteries at first, but after i tried 1, i had to have more. now, i have about 20 turnigies and 8 name brand packs.

my best batteries are the turnigy nano-techs and my worst are maxamps. my maxamps are strictly for 1/10 use lol.

I don't recommend giant mah batteries though.

Let's get one thing straight. If a battery is only so large, you can either get punch and voltage, or you can get runtime and less punch.

Lipo batteries are simply electric gas tanks. You can either get a lot of power and less runtime, or less power and a lot of runtime. Take your pick.

not true im afraid
these batterys isent following any specefic size regulation so the larger capacity ones is also larger in size

the 6000 can deliver more power and amps than the the equal 5000 ones, it also have less resistance..
The turnigy nane tech is great, i have a bounch of lipos including hyperion and i can say the nanos have alot of power.

That a esc fail isent that uncommen for many reason but blaming somthing else is just not necesarry, it could have been many things like snow, water, wiring, connector, servo, heat, soldering ore perhaps even the esc failed becouse of years of stress ore faulty components.

Huh?!

Ofcourse, if you got a battery without enough capasity (constant amps) for youre system, it`s not good enough..

But why dont you recomend large mah lipo`s ?
I cant find 1 reason, except weight..

By choosing a large mah battery with enough amp delivery for youre system (mah X **C +headroom since you cant trust the manufacturers), you CAN have more runtime + maximum punch..

If i remember my lipo theory correct, **C is not an amount of power delivery, it`s a factor for calculating it..

C rating is calculated as you describe. You're missing my point. Large Mah packs are often 2 "other" packs in one case. All of this adds up to more resistance,etc.

Have you ever seen a 4s 9000mah 60c pack ? no

I know for fact that batteries can cause esc failures. We've tested it, and seen it. Even though your batteries are rated "here" they may not be performing "there".

Rx8's with blown caps are likely failed due to poorly performing batteries, period.

I completely agree with all the except for the statement "Large Mah packs are often 2 "other" packs in one case. All of this adds up to more resistance". Large mAh packs are usually in 2p (or more) arrangement, which would decrease the resistance by half the amount of a "1p" pack.

But, yes, ESC failures where caps are overworked are definitely caused by the battery being pushed beyond its real-world rating, no matter what the C-rating, mAh capacity, or number of parallel cells. It doesn't necessarily mean the pack quality is poor; it could be a setup issue (geared too high, improper components for the vehicle, etc), or any number of other things.

And FWIW, I don't like 2p packs; more connections to have issues...
