7.4v lipo receiver battery for Spectrum Receiver

I'm currently using the following Spectrum receiver:
1)  Spectrum - DSM 3-Channel Micro Racing Receiver
2)  Spektrum - SR3100 DSM2 3 Channel Racing Receiver

Any c-hing can share the experience that whether the Spectrum receivers can directly use the 7.4v lipo receiver battery without the lipo regulator?
Thanks!

是可以用的

但一定要加降壓器(BEC)

如果唔係有機會燒

因為7.4V li-po充爆左係8.4V的

不過燒左唔緊要,SHIPPING番去 Spectrum

都係等百幾日就會同你修理番

仲有一提如果用左li-po做接收電

因為li-po太輕你要加鉛同用銅電池板

i don`t recommand u to do this,.. it won`t burn  yr receiver in the first few month ....it has problem if u use for a long period of time, it just suddenly burn yr receiver.

and y need Lipo ? just use normal nimh is ok la....now 1500mah is enought for u to play for 1.5 hrs. it cost less and cause less problem ... u think about it, .u connect one more thing , it has a higher risk of short cicurt and bad contact. and the nimh is cheap ...just $90 ....and lipo cannot be empty ..it will died and the voltage will drop off quickly or even cut off itself when u run out of batty , ..mean yr car will suddenly lost control.  if u use nimh, ..it will let u at least come back to pit or stop the car.

my experience is , i use lipo before, ..but now i chnage back to nimh.

Bull, Justin & Gaspower C-hing,

Many thank for your advice.

咁近engine又高熱, 由其Lipo咁野火.....

唔知小弟好運定''-6'',我有差不多7個Spectrum sr3001接收,一半都用7.4V li-po做接收電,直入接收,冇用降壓器(BEC)嫁,都冇事喎^^  其賣Spectrum綱上都有提過啲接收,9V直入係冇問題,問題只在於啲servo頂唔頂得住啫,高手''林峯Bull''兄,有錯請指正 @@

重點唔祗 "單單" 考慮 lipo 電壓高低, 而係需要注意 lipo 電,
過度使用時, 電壓太低, lipo "自爆" 問題！        

所以有 ching 提出, 用 nimh 費用亦唔係高, 無謂 "為左 lipo, 燒左架車" 咁解,
you know......... ?

Spectrum接收用7.4V li-po係無問題,最有問題係D servo頂唔到7.4V

對, spektrum rx最高電壓係9.6v. 當然配返support 2s lipo電壓嘅servos.

都係果句la

7.4V鋰電,你燒接收,servo都唔好la

都係加番粒$50既BEC la

接收係五六百,SERVO又係五六百

我第一只燒左既2.4接收就係DX3S控跟機果隻細接收

當時係用E-SKY果D 7.4V 750MAH果D鋰電仔

spekrtum rx+ lipo servos咪5燒law.

DX3S RX燒...係因插錯3.3v個插口.
又5見我個3300T燒

Thank NitroChicken, Cold & IS 520 c-hing.

I currently use S9451, S9402 & Sanwa ERG-VZ servos. Can they support the lipo voltage?
How can I check out whether it is a lipo servo or not?

Thanks!

9451,9402,ERG-VZ唔係lipo servo.
Futaba 未有出lipo servo
目前只有JR(Z9100HVS/DS8711HV) , Sanwa(HVS-ZX/-ZV) , HITEC(HS7940TH/7950TH) 有出lipo servo.

I see ......

Thank NitroChicken!!
