The top is for an IB NiMh cell (which people have used for receiver packs, I certainly have) and the other is for a Sanyo NiCd pack (also can be used). The top one starts at 1.5V (at 30A discharge), the bottom at 1.6V (at 20A discharge). So, is it possible for a 4-cell receiver pack to discharge, WITH LOAD (or perhaps 20A is considered not enough load), at 6V (or more)? Yes, it certainly is, in theory and in practice. It's not for very long, but it's certainly there, and certainly above 5.3V. Probably won't happen with the limp 1000mAh pack that came with your radio, but with a *good* pack, yes, why not? Yes, it certainly would be better if people started doing some research before saying things.
For saving costs, all the components on a heli are pretty much crucial/essential, and can be improved in some way. If you wanted the best in everything, you'd be doing that second mortgage on your house in no time. What a person spends on his heli is really up to him to decide.
I personally have been using a cheap 3A 6V BEC/lipo combo for more than a year with no problems. To each his own.
And I don't run stepdown on my 4.8V digital servos. |
