Thanks for all the suggestions! I wsn't expecting quite so much input lol.
MetalMan, I think that configuration would actually fit! I hadn't thought of that setup, so thanks for the drawing. I've been thinking about it though, and it looks like it's gonna be pretty expensive after all to do a 6S2P setup with A123 cells after all. Obviously the DeWalt packs only come with 10 cells, so buying another complete pack (or even just two separate cells) would begin to work out to be kinda expensive. Also, wouldn't the spot-welded tabs strangle current output? I've not used A123 before, so I really don't know. If I went with 5S2P then I'd obviously lose quite a bit of top end, and a box-stock nitro Havoc is capable of 55mph...so I'm aiming for that kind of speed.
TT01 Mamba, I'll PM you shortly about that.
Rootar, I'll keep that in mind....shouldn't be too difficult to do.
TC3Racer,I don't think1P would be enough for my application. It's going to be a basher, so I really want more runtime than 2300mah can provide when I'm bashing out and about. 1P would also cause a lot of voltage drop with the 1515 1Y too, as it's fairly amp-hungry...so I don't think 1P is going to do it, especially when I'm geared for 55mph or so. Thanks for the suggestion anyway!
Whats_Nitro, I know...I was looking forward to completing it too, but I have good reasons for stopping the project which I shouldn't really mention here.
It's annoying, but at least I'll be able to use the Havoc everyday. I'm going to sound thick here, but what do you mean by a DDOR setup?
At the moment it looks to me like a single large LiPo pack is going to be easier and cheaper to do...A123's durability is very attractive, but I don't think they're going to be practical in this particular truck. I'm thinking that a thin lexan "case" around the LiPo (I think someone on this forum did a write-up on that sometime?) and the RC-M battery tray, secured in with a bit of foam padding should provide decent protection...I'm not gonna throw it off cliffs lol.
Thanks for the help anyway people, I really appreciate it!
Might use the A123's in another project someday (something a bit larger with slightly lower power requirements lol). Does anyone here have any long-term opinions on the Zippy-H LiPos? I've read the odd positive comment, but they're amazingly cheap for what they are...
