Has anyone here used resistors to lower the voltage of the main battery, to power lights etc?
Im currently using a step-down module that works great, but I cant use my hobbyking reciever switch since it requires a common ground wire.
I got some help from @Ishayc with the calculations and I´ll be using two 5W 300ohm resistors in parallell from my main 12s battery. The lights are running on 10-16V and 0.23A.
Im excited to try this out, but until then it would be nice to see if anyone else has done it.
