With regards to running a seperate receiver pack as well as the BEC within the JIve,

This is what Kontronik recommend, (From the manual)

The use of a 4 cells receiver battery pack is recommended (see safety information) at a BEC Voltage of max. 5,6V. The pack is connected parallel to the speed control into a free port of the receiver. This raises the reliability of the receiver due to double safety. Charging the battery pack by the BEC is not possible, so be sure that it is fully charged! At higher BEC Voltages than 5,6V please use a separate redundant receiver battery connected to a toggle switch.

I have the Jive 80+HV and also a Fromeco Arizona Voltage Regulator.

Could I connect my seperate TP 2s 3400mah Lipo reciever pack though the Fromeco Arizona Voltage Regulator and set the output voltage to the same output as the Jive BEC? and run them in parallel,

I think from memory the Jives output voltage is set 5.6v.

Do I need to have the 2 cables running from the Jive to receiver, or can it be done with just 1 cable?

Has anyone done this and be willing to share their setup.

One or the other is my opinion. Depending on your setup the Jive internal BEC is pretty robust. There is your main of course and your slave if you have higher demand servos etc or you want insurance. Jive 2 card is needed of course to change the output voltage.

...Once upon a time there were Nitros, flybars and frequency pins...

I've sent an email to Kontronik about this, but as yet haven't heard anything.

Using a NICAD 4 cell receiver battery pack with a Jive 80+HV

If one were to use a small (700 - 1000 mah) nicad pack connected to the receiver through an ON-OFF switch with the Jive 80+HV primary BEC cable plugged into the receiver throttle channel and the second optional cable connected to an unused channel on the same receiver, would this create any problems?

The nicad pack could be turned on first to allow the receiver, Helicommand, etc. to be powered for a control check with no danger of an accidental motor start and then the flight battery connected. The nicad could be switched off to check that the BEC had picked up the load, then turned back on for redundancy. In theory, this sounds like a good idea, but...

1. There has been a lot of info posted here about not using two separate receiver power sources without using some sort of a blocking diode setup to keep them separated. (Dual UBEC's, etc.) A fully charged nicad is about 5.6 to 5.7 volts. If it has been discharged to say 5.0 volts and is now in parallel with the Jive 5.6v BEC, how can it not be receiving a charge?

2. Is this a bad thing?

3. Is it possible that the Jive contains some sort of a diode arrangement?

4. What are other Jive users doing who want to use the BEC and yet have a separate battery backup?

Thanks

My idea behind their recommendation of only using a fully charged Rx battery is. Imagine that you have an empty Rx battery, then all the current from the BEC is used to charge the battery and nothing is left to drive the Rx. So as you fly the BEC will be overloaded. If the Rx battery is fully charged the only current going to the battery is to top if o the off.

I am presently flying with a 80+ HV and have 4 NiCd 1500mAh in parallel with this is working very well, so far :-)

Just my thoughts

Have the problems with the Jive 80HV been resolved yet?

I believe jrockstuart is referring to a different thread.
http://runryder.com/helicopter/t538736p1/?p=4493839#RR
The information on that thread speaks for itself and is not directly related to the issue discussed on this thread.

If you follow this particular thread in its entirety, there are multiple problems discussed such as a 80HV blowing a capacitor among others. This thread is over a year old, so I am wondering if there is any follow up to those problems.

I've got 5 of them no issues at all to speak of anymore.

2nd battery

Hi guys,
I am using the Kontronik Jive 60+HV and have a separate battery installed parallel to the Jive's BEC.

Several of you raised the concern that this could create some problems.
I can assure you it does not!

Kontronik's statement is not quite right, I think.
If the Jive's BEC is set to, let's say 5.8 Volt and the 2nd battery falls below that, the BEC charges for sure the that little battery.
I am using an 800 mAh Eneloop pack and purposely discharged it to see, if the BEC charges it. Yes it does.
Of course it will not be fully charged in a typical 9 Min. flight and also will not die from overcharging for the same reason.
And the worries because of the additional current draw for charging the little pack is unnecessary in my humble oppinion.

Just look at the numbers. The Jive BEC is capable of delivering a constant 5 A and 15 in peaks for a short time. . .

@keithm
yes, you are right, that's the way to do it.
I am using a little plastic battery box from Radio Shack which can hold 4 AAA batteries. This box came with a little on/off switch and works great.
I attached a servo cable (just red and black) and the whole thing is about 70 gramms.

Does anyone know if the Jives are waterproof like the PowerJazz is waterproof by being sealed?

Ummm... to many. 6 Logos, 1 600N, 1 450 Pro, 1 Protos, that's about it at moment.

The red material the Jive is made from is the same what is being used for fillets in restrooms (silicone). So it should be (drink-)waterproof

But then you must isolate the BEC-connectors and the programming bridge.
