但兩粒lipo電咪7.4Ｖ,AD board surport 到?

作者: sumandy 時間: 2007-11-2 12:19
老師.. 問問你如果用 123A果D 3.7V 鋰叉電唔知得唔得呢?
我都想試下用7.4V...
將2粒123A 3.7V 800ma 電放上MR02 個電池架上都OK woo...

有乜要注意? 唔知有冇AAA size的Li電呢?

Yes. The AD board can handle 10v. Of course you have to change the fets to play safe.

No problem. But:
1. the dimension of the 123A is not desirable if you wish to obtain a low CG.
2. the li-ion is not as advanced as the li-po. Check the specs and the history of development of the 2.

Yes, but I could only find something from "LG" which was claimed to have 500mah but people on the net reported it has only 310mah max. So, it is rubbish.

I guess brand name companies are not likely to produce aaa lipo because they do not want to confuse the consumers and then receive complaints. So, let the small factories in China do that.

I did the former, not the latter but I am using spectrum receiver in one of my mini AWDs plus an ESC from novak. It works too.

So if the AD board has FET upgraded, and we can find Li-po 7.4V that can fit into the original 4 AAA battery holder.

We can use cheap motor and have good speed and response?

Even faster than the hand-wind motor with 4.8V intellect?

Not for mine. But you can find similar products from the RC helicopters that have the protection circuit to avoid high current discharging. In Shenzhen, you can find both. Ask the seller about the 'C'. '8c' is already very safe if you play with the miniz using 2 cells.

8C tells you that you can drain the battery at up to 8 times that capacity. If the battery is 800mah, the max current drawn can be 8 x 800mah = 6.4amps an hour.

I found something as high as 30c for helicopters but the downside is they are usually bigger offering the same capacity and thus, I guess, heavier too.
