RE: help i need a battery guy
 

those battery's wont do.

a 900 will put about 60 amps . your going to need to run a min of 12 cells each motor and one esc for each motor.

2 of these per motor

http://www2.towerhobbies.com/cgi-bin...?&I=LXMND3&P=7 this is what some one on this page said to use whaty do you think thanks rye

RE: help i need a battery guy
 

oh HAHA . i forgot about that
ok well if you want the most volts for the most speed hook them up in series you will get 14.4 volts at 3800 MAH
if you want a good run time then hook them up in parallel for 4600 MAH at 7.2 volts

RE: help i need a battery guy
 

ok can i use this http://www2.towerhobbies.com/cgi-bin...?&I=LC2802&P=1

RE: help i need a battery guy
 

yes that is for parallel. and you will get 7.2 volts at 4600MAH

RE: help i need a battery guy
 

P109. we have many of them in our club
one has 3 550 motor on one of the SC480 esc's with 2, 8 cells in series. and the motors are in parallel

RE: help i need a battery guy
 

this boat is 5' about 9 lb with out the batterys how who you do it only 2 900 motors for speed or long runs i want to get up on plain with it ,rye

RE: help i need a battery guy
 

i know the boat. they are all the same length.
I would suggest a gell cell "lead acid " battery.
of around 4.5 ah( 4500mAh) and around 12 volts
that one battery would do the job
