Title: Lipo batteries & brushed motors/escs
Post by: mudway on January 18, 2013, 09:05:41 am

Apoligies if anyone has asked this question, but I associate lipos with brushless motors. Is there any problem with using them with brushed motors and a brushed esc like Electronize or Mtroniks?
I ask as a club member has a model which is not performing well using lipos, an Electronize esc & a brushed motor. Several of us use the same motor and esc with either nimh or gel batteries and they perform extremely well and are quite fast for their size ( his is smaller!). Comments about the captain water skiing again are made when my Cleo takes to the water.  :-)

I use with brushed motors all the time- no difference. The main thing is not to run them down too low, else you kill the pack.

Same here. Lipos for pretty much everything now.  But get yourself one of these

Just connect to the balance plug and when the voltage drops too low the alarm will sound


*Other Voltage alarms are available from other sources.  I picked this one at random as an illustration of what is available

Boeing can recommend a reliable brand for you.

This is better than the alarm, but more expensive I agree. It effectively makes your brushed ESC work like a brushless one and reduce speed when the battery voltage falls, so that you can recover your boat. Particularly useful if your hearing isn't 100% :-)
