Why, they even last on 14 cells.

jhautz, can't lipo be alot higher in voltage when charged then a nimh battery. i remeber a friend using 14 cell ib 4200's and burnt out 4-5 motors....thats was funny a dom?

If you add spacers in between motors and bracket it will help a lot with cooling problems. Better then extra heatsinks... Will work only with motors with built-in fan, like Titans, but not with like Trinity mild/wild/pro.

ya, i made some custom H sinks for mine alswell

Even though they are charged at a high voltage, the voltage noticably goes down when accelerating, so does the amperage.

I bet the titans would be able to surpass a test or two with 5s lipo or 16 cells.

well i figured that.....sorry im a lipo noob guys

And 20 cells with proper gearing :)
18-cells was my favorite setup, so 5LiPo won't be the limit for Titan's, but would be for EVX. Super Duty XR would be sligtly better in that respect...or modified EVX

And bottom line not more then 180-200W from single 550 can

@ turbo4; do you like your dimensionengineering lipo-shield?

[coolhandcountry]

I found the lipo put more punch out so the motors would get warmer faster. I dropped the gearing a little and it would run cooler. It would also wheelie in second gear almost at well.

Yes, Im going to run (2) 2s2p 7.4 maxxamps 6000mah's. I have not got the packs yet(should get here this week) I have not even drove the truck yet, had it a week now just looking at it. Usually lipos will run 1.0v to 1.5v over there rating at a full charge. A lot depends on the quality of the charger it seems. Since I have not ran the truck I cant comment on the Lipo shield.

Where can I get a set of heat sinks for the stock titans?

[Sylvester]

You can check towehobbies, im sure they have got one.

[Mike.L]

or you can make one, what i did was get a 1/4 inch alu pipe and cut it in half and then with a band saw made fins and superglued them to my titan motors...

i couldnt belive it that it worked so well.. and has cheap Money wise:)

hmmm interesting... so you can run lipos on the evx? whats the little gadget that was mentioned earlier? does that allow the use of the lipos? anyone got a link?:030:

dont exceed 200watts per 550 can... good advise!:027:

so does 16 cells burn out the exv? i have some extra cells layin here..... running 14 now.

What do you need a link to?

16 would be really pushing it in my opinion. I wouldn't.

The "thingy" is a LVC or Low Voltage Cut-off which prevents the Li-Po's from over discharging and damaging themselves.
