HOWEVER... using lipo with your existing brushed combo will give a definite acceleration/top speed improvement but you will need a "stand-alone" lipo alarm which can be bought very cheaply on a well known auction site.. (search for lipo alarm... duh!  ) this cut-off alarm is important because if you discharge a lipo cell too low it may become unstable and/or unusable... you can also find chargers that will do all cell types in one unit, and once again these are to be found you know where!! look for one that has lipo "balance leads" built in...
On the Q. of cell shape there are lipo cells with moulded cases that mimic the shape of a traditional (i.e.[][][][][][] )6 cell nimh/nicd(!) so will slip straight in... you can also get lipo cells that looks like the Tamiya type(i.e. === ) cell...
Hope this helps fella!!   |
Thanks for all the great info.
Would a BL motor come with an ESC? (As I said, I don't know much yet...) Do you know a website where I could look this stuff up? I've looked around, but I never know whatever everything is referring to or what works with what. It sounds like if I go this route, then I won't need a lipo alarm...
Do the connectors on LiPos fit with what I currently have? Every picture I look at looks different and I don't see how they will be able to work together.
Last question (for now). Do I need a 2S, 3S, 4S, or what? It seems like 2S is standard but 3S might be faster, as long as it fits with my set up?
Thanks again!!
