Following up from my previous comments on Li-poly cells some new information has come to light following some research on this subject-
Li-poly cells can easily become damaged due to being discharged too low,what happens is the BEC will come in at a set voltage governed by the requirements of the receiver and above all the way the speed controller will take the current from the Li-poly itself,this is where I went wrong and it now appears that a dedicated speed controller set up is available to get around this problem.
The SCU required are what is termed lithium friendly and are so designed that the voltage can be set higher to avoid any discharge of the Li-poly cells,this may require some careful settings to be installed prior to use but it is the only answer to avoid expensive cell damage.
One unit that fulfills these requirements is serial number 4460915 which should prove adequate protection for small electric motors run on Li-poly cells such as the popular GWS powerplants.
It cost myself dearly prior to this knowledge that I feel the manufacturers should have provided to avoid the damage that ensued to my batteries,the notes above should provide the knowledge required for other modellers to avoid a repetition of this problem. :exclaim:
