Yeah, sylvester, for bashing 16 cells already is more than enough.

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?

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.

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
