Lipo selection help
 

I recently ordered a pair of 4600Kv mamba maxx systems after mike gave me some very helpful advice, but I now have the problems of selecting batteries and have some questions (hopefully I have put this in the correct place!)

First off what discharge rate can high capacity (4500mah) Nimh cells support (in your experence?) 45ish???? or more????

The two systems will be going into my tamiya wild dagger similar to what dagger thrasher is doing. I am really looking at the Poly Rc 20C range, specifically the PX3S-4350 which has 4350mah, is a 3s pack and supports 85A continous and 130Amps peak. Is that enough current as the castle creations controller can support 100A continous. I would have two battery packs, one per system - and they would be, as it were, independant of each other. 85A seems a lot, but some people are not sure and I really do not have the experience to say. Surely I always thought 45Amps max for nimh compared with approx double for lipos. Also what sort of current can deans cope with?

Thanks in advance

I run a 4600 system on 3s 3800mah, 76A continuous. Works AWESOME!

The other one I am thinking of is the maxamps:
New 20C MaxAmps Lipo 4000HV 3S 11.1V Pack
which is cheaper, but it has lower capacity - but does weigh a lot less. Which should I do for?

I am running the enerland 5s 5000mah 20c cells, and they are awesome. 100a continuous 150a 30 sec, and 300a burst.

Less weight is always good.

I would always opt for a slightly heavier battery solution rather than skimp on capacity simply because larger cap batteries will have a higher current rating (assuming 20C) and have less chance to heat up too much. But that's just me. :)

Im running enerland 4350mah 5s packs in my cen matrix. I think the polyRC packs you are talking about are built from the same cells. I really like them. They run great.

yep< I do believe they are on in the same.

I have some guestions. Where i can get good LiPo:s in my e-revo? I have soon Mamba Max controller, and that mean i cant use safely >4s LiPo:s... Is that: http://www.rc-monster.com/proddetail...P80003s&cat=18 LiPo good?

maxamps-Mike, and you can actually use lipo safely with the MM. You needa ubec though, which you can also get from the Mike store! :)

Nice, i know it i can use 4-5s lipo safely with ubec:027:

I want 14.8v lipo, but i dont have see more than 3700mAh 14.8v lipos in RC-Monster store, and 3700mAh is not enough... I want more mAh.

Why not get 2 2s2p 8000mah lipos off mike, or do you only want to use 1 pack?

It is possible that I buy 2 2s2p 8000mAh lipos off mike:027: But I'm scared my mamba max smoked cause too much weight, is that possible? I dont want destroyed controller or motor...

With the maxamp packs, you need a 2P to power two 4600's. with the enerland 5000/4350 cells you need 1P. 2P gives you longer runtime than 1P
