I want to run a small buffer pack on my kosmik 160. Just to verify, I think I need to tie the buffer pack into the Kosmik's slave channel port using a y-harness. It's also my understanding that the kosmik's slave channel will charge the buffer pack as well. I plan to set the kosmik's bec output voltage to around 8 volts for my high voltage servos and then use a 2s lipo for the buffer pack. Is this a correct setup?. I just want to double check before I proceed and make sure it's correct. Thanks, you guys are very helpful.

Thwt is correct.. I use that setup on my speed, and a buffer pack plugged directly to my vbar on my tri 800

That's the way to do it....

Also use an "inline" HD switch with my buffer pack....so that for bench testing the avionics....don't need to engage the main batt.

No worries about accidental spoolups....

Sounds good and thanks again. I've always liked the idea of a switch or similar by being able to power up the receiver and servos without the esc and motor being powered up. It's much easier and safer to work on!.

A switch would be nice.. But plugging the pack in works just as well : )

Plugging wears out the connector pins

Here you go guys. This battery will solve the problem of wiring a seperate switch and having to plug and un-plug the battery. It has a built in switch right on the battery. It should be just fine for a small buffer pack.

I'm using the Futaba heavy duty switch between my buffer pack and electronics. It's a reliable switch that's been around a long time.

This is what I am using
Optipower ultraguard 430 super combo
About 40 bucks it has a built it switch also

As long as you understand the operational difference between the Optigard and a buffer pack.

I was wrong the optiguard is on my goblin. I just have a 2s lipo on the Heli with the kos. Sorry !! Thanks dr b

Took me a while to understand what Dr. Ben is saying, but he is absolutely correct (of course). The Ultra Guard is NOT a buffer pack, I love what it is and what it does, in the correct application, but it will not suffice as a buffer for an ESC.

I'm using the same switch as Ace...very reliable.

Just saw your last post Cobra...I use the Ultra Guard on my other helis also!

As soon as he wrote it I went DAHHHHH !! The optic guard won't power up the esc Until there's no voltage !!! Unlike the buffer pack , That you turn on first befor You plug in the main pack ! (I had a brain fart anyway when I said I used the opti with the kos., wrong Heli ! )
Thanks Dr Ben

I now have a small 430mah buffer pack tied into my slave channel that is always powered on during flight. Now, understanding the differances between a buffer pack and the opti-guard, is there any advantages or dis-advantages betwwen the two?. I kind of like the idea of a buffer pack because it is always supplying power to the reciever. But then again, the opti-guard should do the same thing, and is only triggered on when a drop in voltage is detected. Any thoughts?.

ALSO
Using the Kosmik bec, I first plug in the buffer pack to power up the reciever and servos, then I plug in the main flight battery pack to power up the Kosmik. Then fly. With the opti-guard you would not be able to do this. So,(correct me if I`m wrong) the buffer pack system is intended to provide back-up power for bec systems?. If I was using a non-bec system with a dedicated reciever battery to power everything then the opti-guard would be the better choice for back-up power?. I guess I do need a little explaination betwwen the two!. Thanks again.

Since I'm newer to all this electronics I could be wrong too ,
But here is what I think ! My goblin has a bec running from my main pack to the rec .
If the main pack fails the optiguard will initiate and power my rec. So I have control to an auto , I also bought the optiguard super combo that comes with the bat and a very bright led light that turns on when the optiguard is working . So if just the bec fails the opti will get u down safely .

I like to keep things as simple as possible, there are few things as simple as a battery plugged in to something to supply power. In this case, the buffer pack should act as the opti does to gaurd against voltage drops as you will always have the battery plugged in. The battery also gets charged by the BEC from the kosmik. Win win in my opinion. I may wire in a simple switch as some have suggested as plugging and unplugging will cause uneccessary wear on pins. I wouldn't waste my money on an opt-gaurd when a buffer pack can be had even from the top manufacturers for $10 or so.

I'm with you on this one. I like the idea as well.

+1
Though a buffer pack of reasonable capacity and voltage will surely power your radio in the event of a BEC failure, its real benefit is to flatten voltage peaks and troughs in the output of the BEC. The buffer pack is real time all the time in the way it operates to stabilize system voltage. There is nothing wrong with an Optiguard or similar device in intrinsic design, but they are reactive devices and only kick in if the overall system voltage drops below a set threshold. In this regard they will surely save your model, but they are not going to flatten out the BEC output in the manner of a buffer pack. The shear simplicity and comprehensive nature of the benefits of a buffer pack as applied to a Kontronik esc make it the preferable choice for me.

Yep, a buffer pack is best all around IMO as well...
as long as you remember to turn it on!
This is where the Ultra Guard wins, it turns itself on, and no switch required - even simpler than a buffer!

Too bad someone doesn't design a system that accomplishes both!

And I haven't found a decent buffer pack for less than $30, where did you get one for $10 Jeff?
