Could this work? 4 cell transponder voltage booster module, part# NOV5485 at stormer hobbies. Maybe it can be between the esc and the rx to boost the voltage to the rx, servo and the transponder to around 6 volt. (1 cell lipo) heard talk about some sort of volt booster to not deal with a rx pack. I've not been on the message boards that much to know the latest on the 1 cell lipo. Hotrod

From Tower Hobbies description:

This voltage booster is designed to be used only with personal transponders and cannot sustain the current needed for a servo or other accessories powered by the BEC or receiver circuitry.

We will be releasing info on our Smart Boost soon for the 1s lipo racing.

Wahoo! Put that in my Christmas stocking

Thanks Novak two, the 1s lipo racing is looking better everyday. No rx pack, ssswwwweeeeeeettttttt!!!!!!

Novak2, thanks for big orange's support of of oval's future.

Santa could put one in my stocking too and I could hand down my reciver packs.

The new module won't be ready for Santa's toy bag, but we will get it out as soon as we can!

Just courious, where would the 1 cell lipo power booster be install, between the speed control and the receiver?

Would this be able to power the servo too? Thanks Novak for what you do for oval racing.

Any pictures with it installed? The pics on the website would be much better if you could see what kind of plugs are on it, and some instructions on how it needs to be wired up.

How can that be legal? Won't it make the car faster?

I would think it would make it slower (not much, as this cannot take that much power to charge up). If you use a reciever pack then you can run all of your electronics off that battery. With this you have to run everything off from the single cell battery.

I guess what I'm wondering is does it go inline with the plug form the ESC to the receiver? Would that plug into the booster and then the booster to the receiver? Kind of like a reverse regulator.

It appears from the wiring one end will hook to the main 1S battery and the other will plug into the reciever taking the place of a receiver pack. The only concern I would have is the following spec:

The Smart Boost was designed to be used in small or medium-scale vehicles and with 1-cell Li-Po battery packs, such as SMC's® 1-cell Li-Po pack (#SUM4025S). It also has a Li-Po cut-off feature that will interrupt power to the motor when the battery voltage drops below 3.3V to prevent damage to the battery pack.

Is a 3.3v cutoff too high?

I have forwarded your questions and suggestions to Engineering.

seems to high!

I heard it needed to be like 2.5?

oh, that makes sense. sweet

It boosts voltage from the 1cell lipo to the receiver/servo/transponder ... it has a 3A rating.

Steve.

How is this achieved if the unit only serves as a Voltage Step-up between the pack and receiver without any interface with the signal leads and/or motor?

The 2S cutoff in the Novak ESCs is 6.25 so I would figure that 3.1 would make more sense. I think If you get down to 2.5V (even under load) you might risk damaging the pack.

The directions that come with the SMC 1 cell clearly state that the battery can be discharged to 3.0V but should never go below 2.7V.

Steve, are you currently using one of these, and is it necessary?

I have been running 1 cell lipo 13.5 motor pan car for a few weeks , with a 3pk and spektrum module and a personal transponder - NO receiver pack and the car has been glich free and the transponder has been counting fine also.
And i'm not using any voltage booster either, So is this going to be necessary??

Butter's what speed control are you running I see no reason to run booster if you are not having any issues with car shutting down due to low voltage, and transponder is counting the only other issue would the min. weight. You would a few oz. lighter than a car with voltage booster or a car with a receiver pack.

i'm running the XBR esc (because i'm cheap and it seems to be just as fast as a GTB in 17.5 +13.5 racing

Nice!!! Now I can order those 2 lipos for my 12th scale.
Now I know why i have been a Novak fan for all these years.
Thanks guys:woohoo::woohoo::woohoo:

Maybe SOMEONE can clarify but when you have a VOLTAGE DIP below 3.0v per cell on a lipo, and have a discharged voltage below 3.0v per cell, I don't believe those are the same thing.

So a hotter motor that pulls more amps could cause a pack to dip below the VOLTAGE Cutoff "under load" but that would be loaded not static voltage... so maybe someone can explain how that part of a LIPO works.

I've seen questions about that asked several times.

Just test ran my 1 cell / 17.5 truck today for the first time and it did great with the XBR and a Losi Micro-t receiver pack. The Losi only weighs 1/2 an oz so it's no big deal to run it, chassis needed a little weight anyway and I know that I wont have a problem.

The Truck was on rails and even though compared to 21.5./2 cell it's way slower it was still pretty cool...:cool: only .7 to 8 tenths off 21.5 pace. Really caught a lot of attention and I know will absolutely be a slammin entry class. :woohoo: You could put together COT package with single cell and have some great racing.

We have a big track and my lap times were 4.92 to 5.0 without one glitch and could run as long as I wanted.

I attached a picture of the electronics so you guys could check it out.

Actually a Lipo cell can be discharged down to 2.7V underload. I think the Novak cutoff is a bit on the high side but under a 35 amp load the capacity that is left from 3.3v to 3v is only 20 seconds at most.

From what I understand the cutoff only kicks in when the voltage is consitently low not from voltage drop due to acceleration.

I think this Booster is the perfect thing for single cell racing as it will give your servo the proper voltage and the cutoff is a great feature.

Ok can anyone give me a real answer in simple terms how this thing works?If it works like a power converter on a car or truck they have to running to keep the voltage up in the car so it can be converted.I just don't understand how you can maintain enough voltage without constant currant supply.

http://www.rowan.sensation.net.au/electronics/stepup.html

...gives the idea. Not sure what you know about electronics, but this is very simple.

So given the fact that we have to add weight anyway the receiver pack is still a better idea correct? WIth the voltage booster you have to power the output coil, or capacitor with something, and that something is your 1C pack. With a receiver pack you will have more voltage to your motor. I am sure we are talking an unusable amount, but every advantage counts right?

I will always use a receiver pack...until someone invents a true perpetual motion device.

That's what I was wondering because with converters the main source of voltage is converted to a higher voltage but as the main voltage decreases so does the voltage coming out.So without the main voltage being replenished wouldn't it be a disadvantage over a receiver pack?Thank's Jason for the link,I understand how a converter works it's like a coil on a car it turns 12 volts into 30,000 volts but as I was saying it is always got the proper amount of voltage as the alternator keeps the system at the right voltage.I'm just wondering how this maintains the voltage needed without being replenished.It all sounds great if you don't have to keep recharging receiver packs just want to make sure that nothing is lost for performance.

Most of these solid state devices have a voltage regulator in them. It should put out the stated voltage until the supply voltage go so low it no longer works at all.

I think it will also be determined by what motor you're running. The 17.5 I was running went about 6 minutes and had plenty left over. I'm sure that the 10.5's and 13.5's will draw a lot more voltage.

The Losi micro T battery is the absolute trick. It weighs .05 oz and I used it for two days without recharging it and when I did recharge it with the charger that it came with it only took 20 minutes to recharge it which is less than half the normal time. I'm going to get some good run times in this week and weekend and hopefully get some more accurate numbers.

BTW, in the area of gearing, the more I went up the faster I got until I reached a point where I felt I had too much gear and backed it off.

Bill

Now this may be a dumb question with not enough research on my end but where does the losi battery plug into? It's a little to late to dig to find this answer, thanks

the receiver!

I knew that part of it but I'm guessing the aux port? I have the spektrum sr3500 reciever. Also I know that the micro t battery has only 2 pins... what side of the reciever because it has 3 pins. I know these questions aren't exactly the smartest I'm just curious as I would like to use it for the 13.5 single cell but don't want to mess anything up. Thanks, Jay

Red is positive, black is negative.

Thank You Hank... I assume you need the losi charger for this batt? Or do they sell an adapter to use with a thunderpower or something along those lines?

I made an adapter for my charger and use my LRP. The Losi charger is too slow.

Does anyone know if the Booster that TQcell sells has built in shut off! Im looking at it like this. I Have A GTB 4cell. Which does not have lipo shut off. I can use this ESC with the booster for 13.5 1 cell and now have lipo shut off. So I can spend $30.00 or so on a booster instead of $160.00 plus on a new ESC.

Im sure that it does not have a cutoff. I could be wrong though.

You don't really need a cut-off, the car will slow and you will know when the voltage has dropped not to mention you can run like 15 min with a 4000 1s and 13.5.

I have one and believe I read that it does NOT have a shutoff for the min voltage of a lipo. But as Brian stated run time is not an issue for racing.

I know that a nomal race is 4 min long. But more than once A track that I race at Has had a ten min. main. I am just concerned about safety. I have orderd the booster and 1 cell from TQ already. New to 1 cell and just found out about the booster from novak. Just looking and learning trying to get as much info as I can. And seeing what my options are.
