Hi all,

I have just bought a Godox PB960 power pack for my Shanny SN600 speed lights, which use the Canon style high voltage connection.

I purchased 2 x Canon style power leads (1.5m), plus a 5m extended lead (AD-214). Only problem is the extension lead has a different type of connector on, and is not the correct Canon fit.

The AD-S14 is the only extension I can find unfortunately.

Does anyone know of any others that are available, or any other cable which may work?

Thanks for any help!

Phil

Just chop the two leads... Make it into a 6m ish lead that works.
 
It's NOT RUNNING HIGH VOLTAGE. The cable is transferring 12ish volts to the speed light. The speed light then does the rest...

Are you sure that's safe advice Pete? If it's using the Canon high voltage input connector then it should be around 270v nominally.

Bob, you have a valid point but I did check that the battery pack has this as its specs:

  • Battery pack : Lithium battery (11.1V/4500mAH) *Battery charging time: Approx. 3 hours
  • 2* Flash charging time: Approx.1 second (full power) *Flash time: Approx. 1800 times (full power)
Please feel free to tell me how this pack is going to Input 270v into a speed light.
 
The packs I know about, have owned and examined, have all had voltage tripler circuitry. I like the Pixel version, which has a twin tripler circuit. It speeds up recharge, and enables the pack to run on only half the batteries (in an emergency).

There is also a heat dissipation requirement - the pack should not be wrapped up or in a pocket.

In addition to Ground and the 300v line, there is a control line which enables/disables the HV delivery.

Care is needed.

Pete,
I should start by pointing out that I haven't seen the Godox version and my knowledge is based on similar external packs that use the HV connector on Canon's Speedlights.
I have the service manual for some older Canon flashes (EZ series) and the circuitry shows that the HV input bypasses the flash's internal HV circuity to charge the main and preflash capacitors and only monitoring is performed. The third pin on the connector lead is used to enable the external HV output when the plugs are mated and the Speedlight is powered up.....a safety feature as Clive states above.

There shouldn't be any surprise that 11.1v can produce 270v as the flash manages the very same voltage from its own 4.8v (from internal cells) when running standalone.

Again, your assumption and advice re the Godox may well be correct but it's not the case for all external packs.

The extension lead is only fitted with the Witstro/Atom connector, rather than any other speedlight connector. Canon, Nikon etc are only available in the short leads.
 
Incidentally, quantum leads fit and work. Their lead is actually longer than the Godoz short lead, and is manufactured from a much more flexible coating, which means the lead will readily stretch much further without undue tension.
I've had the Godox lead pull out from a battery pack quite easily due to tension. The quantum lead has never pulled free from the battery pack in eight years of use.
 
:) Thanks guys, you have all given me some more info to play with.
I also did a quick web search and nothing came back that this pack out putted more than 12v +/-... But will take note of strange connectors...:)
 
Thanks for the info everyone - will probably not bodge my own lead to be on the safe side!

This would be the cable you need, although this particular listing seems pricey.

I did see a couple of options from Quantum, but to be honest the prices are pretty crazy (for me anyway) - I would rather just buy another battery pack for a bit more than blow £50 on a cable.

One other option I considered was this splitter lead. Not the ideal solution, but certainly cheaper than a Quantum lead.

Interesting - even with just a single speed light attached rather than using both connections?

No, my assumption was that you would use both ports.
If you are only going to use one port, then no problem. However, this isn't going to negate your need to replace your Canon dedicated cable.
The Quantum cables can be found a lot cheaper if you keep an eye on ebay, or set up a search alert.

Thanks for the info.

The Canon cables are fine (as that is what the Shanny speed light takes).

My intention was to use the power pack for a 2 light set up, and the Godox power pack has 2 outputs. The power pack would be situated with the key light (so the short cable is fine), and then the second output would be extended with the splitter cable I linked to, and then hooked up to the speed light with the second, short Canon cable.

I will keep an eye out for some cheaper Quantum cables. I had done a couple of searches on eBay an elsewhere online but could only find results around the £50 mark.

Thanks again

Yeah, £50 is new, but I've previously bought "Open Box" and 2nd hand (which hadn't seen any use TBH) for about £25 - £30.
Far, far better cables. Longer and much more flexible.

You seem to be far more knowledgeable than myself regarding the cables needed etc so thought I would run this by you.

Do you know if any 8 pin DIN cable could be used as an extension and if an extended length would cause any issues?

I saw this on eBay (a 21m extension cable) and wondered if it could be used.

You will lose power over that kind of length. It will display as an increase in recycle time. I think @Garry Edwards had a figure for power loss using the standard longer cable, so you may be able to extrapolate for this one.
21m is hooooooooooge!
Shouldn't be an issue with connection, as it will be straight wired from male to female. There is no locking facility on either end, so that would need a bit of thinking about

There will be a massive resistive loss, which will cause a very substantial loss of power as well as much slower recycling.

But I couldn't begin to estimate the amount of loss, because I don't know the spec of the cable. Typically though, a 5m extension results in a resistive loss of around 1 stop (50%), so 21 meters would be... a lot.

Thanks for the info and guidance. Clearly not the way to go then.

I'm surprised it is so difficult/expensive to get an extension - I thought it would have been something people would commonly use with a pack like this!

There probably is a real demand for these, the problem is caused by the very short-sighted business model adopted by the manufacturers.

Typically, most Chinese companies will sell to literally anyone and everyone, with the result that they sell to ebay sellers who have no specialised knowledge, no concept of customer service etc - so they don't bother to stock accessories

After hunting around and failing to find a suitable cable, I have decided to just chop the leads to make the one I need.

I have mapped the pins to the connectors on each lead with a multimeter, and also chopped the leads to check how many wires etc.

The Canon lead, despite having 5 pins in the battery pack connector, and 3 pins in the HV connector, only uses 2 wires.

The extension lead also has 5 pins, and uses all 3 of the pins in the connector, with 3 wires. I believe the extra one is a serial connection to the power pack to enable HV delivery, as alluded to above.

So it seems it will be a simple case of extending the leads with the 2 wires, without the need of the third. Will just have to ensure it is insulated properly and the joint strengthened, but I don't envisage there should be any issues.

Hello I am new here, but was looking for the same Godox PB960 extension Canon cable, but was only able to find the coiled cable. I remember someone mention that the Quantum cables would fit the Godox PB960, so I did a search on Ebay was able to locate the following: Quantum QT49 10 foot Extension Cord for $20 + $6 shipping, after receiving the cable, I connected it to the PB960 and connected the Canon coiled cable to the YN685N and everything worked as expected, so to answer the question Yes the Quantum QT49 10 foot Extension Cord works. I was also able to locate the Cheetha Stand One to Two Cable (9ft/2.75m) $34.95 found here: http://www.cheetahstand.com/product-p/cl-s12l.htm and Quantum QT49 can be located here: http://www.ebay.com/itm/282047854307?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT for $40.00 Free Shipping. This is a very hard cable to find, I plan on purchasing another. I hope that this helps.
