increase battery Mah
Helloto all
I would like to know what kind of batteries i could you use with this transmitter ( sanwa airtronics vanguard 6ch PCM ).my old pack was used enough so i have to change it.In order to increase operation time i believe i have to increase battery capacity.Is that right? So, 1)how much is the most i can put in the transmitter .for example 8 nicd batteries of 2000mah would be ok or there is a problem my transmitter burns? 2)how much is the most i can put in the receiver?i use 7 standard sanwa servos.the max voltage must be 4.8 volts , is that right? The amperage can be , like the other case , of 2500-3000mh? Thank you in advance and i am looking forward you answer |

As a suggestion, you might want to go to the Batteries and Chargers forum of RCU and ask your question to RCU moderator Red Scofield. He is a battery expert. Good Luck, Dave

RE: increase battery Mah
dont confuse amps with amp hour. amps is a measure of force so to speak and amp hour is a term used for duration. ie 200 mah battery can deliver 200 ma for an hour or 2 ma for 100 hrs

Hi!
If you want batteries inside the transmitter;)...2800mAh NiMH cells are the "largest" capacity cells available, that's AA or R6 size cells ( that's what available in all stores today). Just sweet solder together a pack of 8 of these cells. Easiest metod to use is to CA glue them together and then solder small peices of wire from cell to cell. (in series) That's how I do it. |

UNLESS YOU ARE EXPERT WITH BATTERY BUILDING I WOULD SUGGEST YOU BUY A TX BATTERY PACK FROM SPEKRUM THE ONE THEY USE IN THEIR NEW DX 7 RADIO. IF YOU CHANGE TO A HIGHER CAPACITY BATTERY YOU WILL ALSO NEED A HIGHER CAPACITY CHARGER. BETTER TO BUY TWO REPLACEMENT BATTERYS AND KEEP A SPARE WITH YOU FOR THOSE LONG FLYING SESSIONS.

HI!
You don't have to by a new charger! I use my 30 year old JR charger (50mAh and 100mAh) to charge my 1800 and 2800 mAh NiMH cells...it only takes longer times to full charge. Sweat soldering is not rocket science!:D |

Sorry guys.Did you understand my question?

RE: increase battery Mah
You may use any 8 cell battery of any capacity with your transmitter.
The transmitter uses 9.6 volts. How long it uses those depends on the battery capacity. A 9.6v 2000 mah battery will last far longer than a 9.6v 1000 mah battery. If the battery is a Nimh, it will last longer than a nicad of the same voltage and capacity. For the receiver, 7 servos is a lot, and the battery will need to be larger in -capacity- for the load. Nominally the receiver uses a 600 mah 4.8v battery. Go at least twice that, or even 3 times, for peace of mind. 4.8 v, 1500 mah. |
