lipo plan!
 

hey guys,

my original plan was to go back to 12 cells with an 8L to keep weight down, but i think i found a better and lighter solution and still run my 10L. the kokam packs that mike runs are a very good deal now that i did the math. i will be buying a 3s and a 2s 3200mah 20C packs from tower.

then i get another $25 off, so that is about $175 for the batts

problem is my triton can only charge 4 lipo cells at a time and only at 2.5 amps. that would mean over 2 hours of charging. that just wont work. so then i found this charger

it can charge all my nimh batts for the qualifers and then can charge 5 lipo cells (what i will be running) at 3.2 amps, so that means recharge of only 1 hour. the charger is also a killer deal at $82 bucks. looks like im going lipo! just gotta save a little more and wait till the charger comes out. but after thinking about the price and WEIGHT of 3300s, the lipo seems like a way better way to go. also, in all i will save about 1 1/2 lbs in batts compared to my 3300s! they will also fit perfect into a g-maxx chassis. i have heard that if these cells get hit, they will explode. do i need to make some kind of gaurd? thanks guys.

supermaxx your inspiring me. Keep it up.


When your finished figuring out your battery and charger situation on the lipos please LMK how much its cost

If the money isn't to outrageous and the run time can last a 15min main I'm so going brushless on the revo.

Revo conversione wherever you look. That's great guys!

I'll keep an eye on the Lipo thing, but might get me a batch of GP3700 first.

That charger your talking about is great! it is very, very small and very powerfull.

Those Kokams are the real thing.

cheapbatterypacks and maxamps sell 20C lipoly's too (whitelable and polyquests) but i personally take those kokams over those. If you have got the ability to weld on a few taps, you might consider using a charge balancer as well. (i use them for my 3S mini-t packs too) I thought Mike uses his Kokams without balancer.

rc bro- the runtime will be about the same as gp 3300s, but less than half the weight.

serum- do you mean solder on the taps? or weld? BTW. the packs are not in parellel, so will i still need to use a balencer?

ill wait to see what mike has to say before i buy them.

yeah that charger is nice I knew that you would like it. I remembered it from rcx 05 and searched on tower. Pretty mint that something that small can do 5 lipo cells. What amps does it charge at though??

That charger sonds like a good deal, but the astroflight charger is only around $20-$25 more. The astroflight can charge up to 9 cell Lipo packs at a higher charge rate as well, so you wouldn't have to wait longer to charge a larger capacity pack(which will likely be available soon!). I don't balance my Lipos, either.

yes, but the astro flight cant charge nimh packs.

Might even be able to alittle more run time now that there is less weight which mean less stress which means less amps being drawn. Probably won't be a very noticable difference in run time though. I can't wait.

i cant wait either. i may order them later today and use the triton until the new charger comes out.

You already have a triton, so you don't need another charger to charge nimh, do you?

ill sell the triton and buy the multiplex...then i will have an all in 1 charger at a cheap price.

I will still stick with my initial comments. In a short while, I am positive there will be much higher capacity Lipos, and a charger with an ability to charge more Lipos at a higher rate would likely be a better purchase plan. Unless, of course, you could just sell the charger and upgrade at the appropriate time.

I thought lipo also gets longer runtimes?

arg! lol

Lipo CAN get longer runtimes if you have higher capacity. Just because it is Lipo though, doesn't automatically mean it will run longer (kind of like "nimh gets longer runtime than nicads" A 1000mah nimh won't run nearly as long as a 2400mah nicad).
