Default RE: A123Racing Battery Questions

Brian,

Your batteries seem to operate at a slightly lower voltage than conventional Lithium Poly batteries? I assume that the mandatory cut-off voltage is also lower. What is it? If I am configuring a system for aircraft operation that would normally be 6S, do I need to add a cell to work with your system?

Bob
Hello Bob,

We recommend a 2.0V / cell cutoff, though our cells are extremely tolerant of over voltage and undervoltage. 1.0V/cell will not be a problem as long as the load is not kept for an extended period of time. As far as needing to add a 7th cell to replace your 6S configuration; that depends alot on your setup. I know some people are using our batteries at the lower voltage and simply changing to a larger prop to make better use of our high power capabilities. For example; someone using a Thunderpower Lipo was running an 11 x 8 prop at 30 amps, after using our batteries he changed to a 14 x 8 prop at 43 amps with spectacular results. But again it depends on your individual setup.

Brian
