lehner 2250 13turn

[extremexmods]

BK 36120 only. I want reverse and 10s lipo, 2250 13 turn, but may go with 11s lipo and 2250 14 turn if the controller could take 11s lipo. WHen you increase, the voltage, if the motors are the same, what happens to the amp draw. What is the amp draw of the 2250 13 turn on 10s lipo? what is draw of the 2250 14 turn on 11s lipo? Do I need 8000 mah lipo or can I use 4000 mah lipo? Just need straight answers please?

The higher the cellcount on the same motor (assuming you use the same pinion/spur) the higher the current.

If you use the 4000 and they are 20C, that setup can deliver 2960 watts, that's enough in my eyes, but ever since you have got an indomitable need for power, you might as well get the 8000mAh, and yes, the 36120 can take 11S lipo. If you are going for such a high power setup, please reconsider the choice of your controller and get an 36150 instead.

Now, please tell me... because i am burning of curiousity.. What is your plan with this setup?

When you increase the voltage the amp draw will go down, different motor same final rpm, amp draw will vary based on the load placed on the motor--ie gearing, weight of truck, how far you pull the trigger-- I dont think you would excede the controlers rated amperage, the mah rating of the lipos you pick is related to the amp draw and their ability to deliver current. Assume you pick 4000 mah lipos that are rated at 20c that means the amps they can deliver is = to 4.0ah x 20 = 80amps, with lipos you want to make sure they can deliver the amps you need, if you got low capacity cells it doesnt matter that they are 20c rated cells they will not deliver high amps, same with c rating 8000mah 2c rated cells will not deliver the amps you need either. With the higher voltage setup your average amp draw will be less which also means your runtime will be higher, based on that my opinion is that 4000mah would be fine as long as they have a high c rating 20 is what I would (and have got) get. Again it also depends on gearing, if you are gearing this truck to go 80 mph your amp draw will be signifigantly more than if you gear it to go 55 mph. My recomendations are based on normal gearing not 80 mph crazy gearing. I would personally recomend the 3700 mah apogee lipos on this site I have similar lipos myself, obvously you would need 2 packs, I also have and recomend the hyperion charger and balancer.

Like i said;

More cells, same gearing, higher current.

the 36120 is pushed to it's limits on 11S lipo and a 2250, i advise that 36150 for nothing NL12?

The extra insurance of the 36150 would be wise I agree Serum, but if the motor drew 120 amps powered by 11s lipo (assuming the lipos could deliver 120 amps at 3V) that would mean the 2250 was putting out 11*3V*120Amps= almost 4000watts, how fast would you have to be going to summon the power of 4000 watts? Wouldnt it be unlikely for the motor to draw 120 Amps (the limit for the 36120)?

[extremexmods]

where can I get a 36150, and how much are they? Since a 2250 14 turn is a lower current motor compared to the 2250 13 turn, on 11s lipo, how would its' current draw be compared to the current draw of the 2250 14 turn on 11s lipo? Also the maxamps cells are rated at 12c constant, 16c burst. Would 4000 mah packs still be enough or should I go for 8000 mah packs?

[nl12]

Mike can get the 36150 for you, it is imposible to give absolute numbers for amp draw without testing the system but a higher turn motor on equal voltage will draw fewer amps, I would reccomend the 8000mah if you are set on the maxamps cells

[Serum]

It is powerhungry, the 36120 would be okay, Peaks would be insane on 11S but for that few bucks more, i like the insurance.

Again extrememods; what are you going to use this setup for? it would make more sence to me.

Are you by any change the person i talked with about a savage conversion?

[extremexmods]

It is time to knock Promod out of 1st place for the e maxx speed record.
How much does the 36150 cost? My goal is 75 mph. Can a 2250 14 turn on 11s lipo make enough power for that speed?

[Serum]

499 if i remember correctly.

I like Promod though, he is a nice and humble person.

the 2250 14 turn on 11s lipo should get you to that speed.

i havnt seen promod around the forums latley wonder what his latest project is

[coolhandcountry]

the motor and batteries are up to the task. I don't know about your truck though.

[Sylvester]

ya, thats what i was gonna say, your gonna need something like this to hold up that thing!

FLM Hybrid bulks OR UE VBS
UE 8 spyder diffs
23mm dace adaptors
UE 8mm cvds
UE center cvds (or mikes cvds, they are good too)
Strobe slipper(will need some modding, a 2250 on 10s or 11s lipo is A TON of power)

Then theres suspension which is up to you, but for somthing with the power your looking at UE RacerX suspension would be good.

[extremexmods]

Would I be better with 36 IB 4200 cells and a 2250? How would the speed and power compare to 11s lipo on a 2250 14 turn. How durable is lipo when it comes to surviving a crash at very high speeds? Maybe buy 12 6 cell IB 4200 packs, run 6 in series, then switch them and use the other 6 packs. Also, how bad are ebay IB 4200 packs

[stampy]

lipos aren't as durable as a sub-c but if you secure them really good and use some foam to lessen the vibrations then they'll be fine
