is it really worth it???

Theres been too much drama on here this summer. Are we a bunch of women? Most of us are grown men, lets act like it.

Good talk.

well, it's now clear you either a) didn't read my post (#14), or b) skimmed over it and didn't comprehend what it said. I pretty clearly stated that if you are running a stock 60A or so ESC, then you will have no issues. I then go on to point out that if you run a 120A+ ESC, then you may have an issue since each pack on it's own is not rated for that. Do I need to type slower or something?

Yo Kookie.
It doesn't matter if the ESC is 20 amps or 2000. The load is the load (motor and prop)
Also, paralleling packs of the same manufacturer, capacity, c rate, age and # of cycles is perfectly fine.

BTW I run Hyperions and for me they are worth every penny.

Never said I was superior, just wish others would read and understand posts before trying to make a point which was clearly supported in the first place. If something as simple as this discourages you from the RC hobby, then you my friend, need to consider the possibility that maybe a hobby in general is not the right fit for someone as uptight as yourself.

To the OP, sorry for cluttering up your thread. This will be my last post in here.

cheers.

No we'll chalk it up to dickheads with low self esteem who get bent out of shape just because someone doesnt recognize thier obvious superiorty to others. The very same kind of asshole who ruins forums like this and discourages people from the hobby in general... Whatever!!!

[kookie_guy]

Wow thats some attitude you have there

meh, just chalk it up to the failing Ontario education system. lol.

I still fail to see how this will lead to "fire". If a 40c pack is able to supply sufficient current on its own, how will two in parallel cause fire. Even if one pack is working more then another both packs are capable of supplying the desired amount of current.

From the last couple of seasons' experience in my P spec hydro: Turnigy 4S 4000 mah 40C packs lasted one season. They didn't puff after a heat like the nano-tech packs, but gave little warning before dying. The Turnigy Nano-tech 4S 4000 mah packs (rated 40 C when I bought them) don't seem to be as durable. One died and seriously puffed last weekend, while the other is still running with minor puffing and slightly increased internal resistance. Probably the boat needs 5000 mah rating in the less expensive packs, but size is an issue. Gens Ace 53000 mah packs fit in my P spec tunnel and look more promising. Higher priced cells will be worth it if they survive more than one season. the Grim Racer packs look like a middle cost solution.

Which ever one fits best. Fit is most important between the two.

But is the current draw not determined by the load on the motor. And do the batteries not share the load placed on them.

Yes, the current draw is driven directly by the motor and the amount of load/prop you put on it. Those amps are PULLED from the ESC, and the ESC pulls those amps from the batteries.

And yes, in THEORY, the batteries should share the load, but in reality, they don't. The packs would have to be identical in every way. Not just mah and voltage, but cells used, construction, internal resistance, wire length etc. So there's a very good chance that one pack is getting more drawn from it than the other.

thanks guys. If thats the case, I will be able to buy a couple sets of tur/nanos and gens from the money i save from one set of tp. I will not be competing, but do like having the good stuff Probably try one set of each to compare.

This is what I have done and to date I don't see a difference in charging or discharging.Perhaps the difference will show up in a year from now.
