Hot swap for Archer

[Alfeo Dixon SOC]

solution should pretty much fix my "Red-Problem" :D

NOTHING can fix the "RED-Problem"

 

should mention, your batts will drain equally in parallel, so don't let them get too low, because when you go to take one off during a quick hot-swap, IF the voltage is drained too low, the remaining battery will not be able to keep the camera powered up.

back to the Ptap... is it good or not? Ptap port is there, with 10A and 50W written on it, should I connect the 2 plate with Ptap?

You should be fine as long as you connect Batt A's +12V to Batt B's +12V and Batt A's -12V to -12V of Batt B. This puts them in parallel which will double your Amps.

Except by doing it that way you will also try to charge the battery that has a lower voltage.

Thanks for your good point Eric.

 

So... I can power the monitor with the new batt and leave the other for cam, FF, downconverter and Tx-Rx. But if I want to have them work parallel how should I do?

I think Eric is referring to the magic diode to prevent reverse voltage. I know the p-taps are rated at 10a...but can they really handle that? The wires look kinda wimpy in there.

[Matteo Quagliano]

Thanks Ron, don't understand exactly where to put this diode but when I will there's just to put it between the 2 batts and use good cables, right? Then I should have them paralleled. I have to ask Tiffen if the internal power cable can handle that amperage and may be use good cables to go directly inside the main batt plate from the added one.

here's a link to the thread about preventing reverse voltage with some diagrams. It's a pretty simple mod that many are doing.

Thanks Ron, very clear and helpful... I'll go the diode way...

Hi Alfeo!

 

Did you find a solution for the Ultra2 to be able to hotswap? I'm right now looking around for a suitable solution.

 

Best

Yes, is the official answer with placing a diode into series on the plus side of the 3rd battery, from Tiffen. I just need to confirm the way I'm doing it via the base accessory power connection. Will post results in an appropriate new tread.
