Do we have to use Sub C Cells?

It has to be 6.0V?

Give me the skinny just trying to figure out the best possible NON Charging way to go..........

lipo, with voltage regulator 6 volt, 7 to 10 amps model can pm ya with part numbers your supplier probaly has them don't use the novak regulator not enough amperage

Johnny-

Post the information, please.

JB

no problem, at work rite know. will post were and part numbers when i get home. also, i'll post ya some pictures of my setup.

Appreciate it johnnyhacksaw.

BUT why 6v why not go ahead and use 7.4v, hmmmmmm

Servo's can't handle the voltage. They work at 4.8V-6V. They will FRY:o LOL

Also if you are using a spectrum radio system spectrum recommends using no more than 6 Volts. If you do the reciever may not be able to handle more than 6V and result may be severe glitching. DD

Interesting.............. I guess the reason why 1/10 scale electric gets away with it is because of the ESC........... Ok cool, very interesting.........

dyno, the new spektrum receiver (#SR3100 DSM2 3 channel) input voltage range is 3.5-9.6 volts. i'll try and post some pictures and part #'s for ya guy's. havin one of them 14 hour work days......:freak:!

use one of these regulators:





5-cell Rx pack offers many advantages. It is the easiest system upgrade that makes servos run faster with torque. It also provides extra safety margin. When one-cell fails, you still have 4-cell for safe operation. However, a freshly charged pack may cause some jittering. Here is the turnkey solution.
ACC139 Key Features: • When input is higher than 5.4V, it will regulate output to 5.4V, • When input is less than 5.4V, regulator is bypassed, • Weight only 0.4 oz, • Current: 5 Amp continuous,10 Amp peak @7.2V input, • Input Range: 4V -8.4V.

ACC139 5.4-Volt Regulator



ACC234 Key Features: • Adjustable output voltage, • Large heat sink for optimum performance, • Weight only 1.4 oz, • Current: 15 Amp continuous, 30 Amp peak @7.4V input. • Output voltage range: 4.8-16V. Input voltage must be at least 1V higher than output.
Note: Current capacity drops as input voltage increases.

i'm using one of these with an orion lipo 7.4 5000 mah pack

guy's, you can use this also, go to this link:

i'm also using this on a car of mine, works really well

Johnny, Just going on the advice of the guys at spectrum as I had glitching when running a 6 cell pack in my car. After switching back to 5 cells the problem went away. DD

dyno, what spectrum receiver are you using? also, with 6 cell battery are you using voltage regulator?


here is a link of what receiver i use

Has anyone ever considered the a123 2 cell pack. It is 6.6v when fully charged and doubt you would need a regulator since most 5cells end up in the 7v range when charged.

I was looking at the LiFe packs as well as an alternative, but I am not seeing them accepting the loads that well, I dont know..........

I use a simple receiver pack of 5 - 3800ma Nicads, No Lipo no regulator. I can run 3 - 50 lap quallifiers and 1 - 150 lap main without recharging. How simple can it be.

Beside my 3501 & 3305 1/4 scale Futaba servos caution about being used with a Nimh and Li po. Futaba says to make sure the amp draw is sufficent in either pack to withstand the discharge current of all three servos.

Low Tech equals low cost and no drop off in a quality in the power source.

I agree with Mike. In 18yrs of racing I've used a 6 cell pack all but once 4-5yrs ago. Went to the 5 cell for 6 races only in hopes of curing a rash of servo failures which later turned out to be broken wires caused by crashes (Hitec) and cracked cuircit boards (Futaba). Worst part about the 5 cell was having to charge so much with the digitals. Have used Hitec 5645mg for steering for as long as they have been out and have one set over 3 yrs old. Use Hitec 5745mg for th/brk but they can be erratic. One will work great and get good life, the next won't. The H755mb seems more durable but considerably less power. I still use the PCM & 3PK wtih excellent performance. The PCM receiver's reliability is beyond reproach and in my case has never had a problem with the 8.6v the 6 cell provides. I'm a firm believer in new technology, but until my cellphone quits dropping calls (claimed same technology), I dont' have a lot of faith in the new Spek/ Fut systems. I'm sure it will get there, until then, I know what works.

Ill have to agree with that. I use 5 EP 4600 sub C cells to run my RX & servos and I can run all day without charging. Simple is better.

I use our old 3800 red pole position batts and they run all day 2 or 3 practices 2 heats and a main. I would only spend the money if you needed to cut some weight.

Fergie. The spectrum transmitter and receiver do not work like a cell phone, there are no cell towers to deal with, the system works between your radio transmitter and your receiver ONLY and has nothing to do with cell phones and will not drop your car. I have been running Spectrum brand system with different scale cars for the last 1 1/2 year without a single problem even when I was in a area where my cell phone had no signal not to mention the reasonable price of this system over Futaba which I ran for over 15 years before Spectrum with only a few problem but they only cost me a few thousand dollars. Im a firm believer in Spectrum brand system and will never go back and Im sure if you talk to other people using them they will tell you the same. Just my 2..DD

Do we have to use Sub C Cells?

Give me the skinny just trying to figure out the best possible NON Charging way to go..........

latemodel was asking about alternative's... simple is better, i have used 4200 5 cell have had no issues, still do. total agree. but, one time it let me down. i did'nt qualify very good and had to bump up mains to make feature, rain was a comin, there was'nt going to be time between mains to recharge or change out battery. need less to say...i ran a 75 lap, 150 lap and 200 lap back to back never shutting the engine off!... got in the top 5 with about 15 laps left, guess what receiver battery done used up! so, if i think this will happen again, i'll pull this lipo stuff out and use it. there more to the story when the receiver battery dumped, it was scary!

It was a joke Dino.
