So your trigger is connected to the FT-16s?

no no, just a plastic cold-shoe with no contacts, to fit on the hot-shoe on the side of my cam. will use FT-16 is just for flash control, for triggering i use Commlite T320 (as shown in the pictures - the cable is to transfer camera hot-shoe contacts to the side hot-shoe, to use flash in portrait mode)

EDIT: my two V850 arrived. everything working fine. now lets disassemble... ;)

Thanks for clearing up... I understood now.

Can't wait to hear what you can do to make V850 more better. :)

they look sexy in the dark, (external link) but in the light too ;) (external link)

Notes:
The charger car connector is directly connected to the battery/charger monitor circuit. so the original car charger is required (its not just a power supply for the charger)

The contacts inside, shown on review that "looked like" connectors for a possible battery pack/communication/etc are just cut-out parts for internal circuits. they ARE NOT connectors. they are there to help space efficiency, this thing is tightly packed ;P

the battery on the flash is directly connected to a capacitor, so it mostly have a very very low consumption even turned off (will measure later). so is better to remove battery of you will not use for a long time.

Thanks malow, nice mods!

So if the battery is running straight to the capacitor, do you think its possible to connect a high voltage battery pack (330v) in any way? Or does this need to stay 11volts like the original battery?

I was going to suggest the modeling light mod to you btw, that would be very handy having he remote On - Off control on the FT-16.

Thanks agian.

the capacitor i'm talking about its not the main capacitor, its just a small capacitor to smooth and stabilize power. "tecnically", i believe HV Battery packs can be connected to any flash, but im not qualified enough to be able to do it :(

i think most battery packs have 3 pins, 2 for direct connection with the main capacitor and a control signal to start/stop charging. if i had a oscilloscope to analyze it...... :(

yeap, i think i will get power leds and do it... but will take a while to get all the components.... :rolleyes:

EDIT: did a few measurements...

Turned off: 10 µA
Sleeping: 10ma
Idle: 15ma
Idle with FT-16s: 40ma
Charging capacitor(at full-power): 4.8A (looks like it's limited to this)

the consumption "turned off" is way way lower than i expected, so its safe to let the battery inside for a few months with no problem whatsoever.

the circuit looks very efficient power-wise, low heat generated inside, so this should reflect in "long longevity" (but time will tell ;) )

as current looks limited, its safe to li-ion with large capacity/low impedance with no problems (Yn-560ii for example doe not have limit, DIY battery packs can burn the flash unit)

so good so far. finally a cheap and DIY friendly li-ion flash ;)

EDIT 2:

now i realized i can run 2 flashes with one battery pack (1 flash = 1900 full-pops, 2 flashes = 900 full-pops). will make them with two output connectors on each battery pack, so i can use 4 flashes with 2 packs ;)

EDIT 3:

A simple way to calculate flash power is to use the power in watts for each pop. the V850 uses about 0.032Watts per pop, the YN-560II uses 0.045Watts per pop. so we see that a efficient circuit and the higher voltage of the battery makes +25% more efficient than "AA batteries flashes".

EDIT 4: More measurements...

battery indicator:
3 BAR 12.60V ~ 11.35V (3.78V/CELL)
2 BAR 11.35V ~ 10.95V (3.65V/CELL)
1 BAR 10.95V ~ 10.60V (3.53V/CELL)
BLINK 10.60V ~ 5.20V (1.73V/CELL)

The flash measure voltages between capacitor charges, which is very good, and also good average voltages for resting li-ion cell.

its a good idea to replace the battery when the indicator start to blink (empty), the flash will try to get all the power from the battery, but constant "emptying" the battery at low level may reduce life cycles.

also, as current is limited, its very easy to use a AC power adapter to power this flash, and use as "studio flash" ;) (just need to be 12V at least 6A like this (external link)). a voltage regulator can also be used (6A minimum recommended), PC power supply, 12V lead-acid battery, etc...

EDIT 5:
opened the battery, they use "Great Power 1800mah" (?) flat cells, with a protection circuit board that monitor each cell. as most batteries that use series cells, this do not balance cells, but monitor each one to avoid overdischarge/overchar​ge (require matched cell and charge state)

looks like the charger use the standard CC/CV charging, without balancing.

EDIT 6:
tested the battery, it really is 1800mah (measured), making around 0.032W consumption per pop

Hey guys, sorry i haven't really been keeping up with this thread - trying to keep my money in my pocket ya know? ;)

ANyway I saw this poste din the Fuji X forums and was wondering if this is the same product as the Godox.

http://www.amazon.com …hotography/dp/B​00G7H6ADQ/ (external link)

Does anybody here have any experience with these units? Seems like a great deal at that price.

Cheers,

Matt

Yes, TT850 is the exact same unit as V850.

That was my post. It's also here:

The Godox V850/CheetahStand V850/Neewer TT850 are all the same.

Cool thanks for posting. Does this include the trigger to allow manual control over multiple flash units? Seems weird that you get multiple triggers if you bought more than 1. Always good to have a backup though i guess.

Yes, it does.

Package Contents

1x NEEWER TT850 FLASH SPEEDLITE

1x NEEWER Li-ion Polymer Battery

1X NEEWER BATTERY CHARGER

1X POWER CABLE

1X BATTERY CAR CHARGER

1x WIRELESS flash trigger and receiver

Seems weird? Well, they probably didn't intend people like me to buy 4 of these packages. It's probably meant to be a starter package. I don't mind it because now I have one transmitter for each of my Fuji X and Canon cameras.

Hope you already bought it, because it's showing at $150 on my end again.

damn, missed it. Thanks for the heads up. I may do it anyway. Nothing i hate more than climbing the ladder to change the power on the YN560's...

As a word of caution - the package mentioned above from amazon, which is supposed to include the trigger/receiver and mobile charger apparently does not include those two items.

I got in on this when it was at $99.95 - 2 days ago, received my package today and those two items were not included. Read the reviews on that page.... everyone seems to be having the same problem.

I chatted with amazon csr and they refunded me $43 for the missing items :) Fortunately I had a spare trigger/receiver set I had got from ebay earlier.

And yes - this speedlight combined with fuji x100s is a killer combo!

When I bought mines back in Feb for about $99 on Amazon, it came with everything like charger, battery, and the flash. It doesn't come with FT-16s, so I had to buy it separately on Amazon for about $25. So its like paying $125 for V850 + Neewer FT-16s Remote + Receiver.

About two weeks ago, I was looking for a fourth copy but it was out of stock everywhere... So, I had to get it from Godox directly and it arrived about three days later.. From Hong Kong to USA... and it came with Godox V850 + FT-16s remote/receiver in the same box! :) the Neewer Remote does works with Godox Flashes.. no differences on name brands, still same manufacturer from Godox.

Did anybody measure power out of these? How they compare to say SB-900 at 24/35/50mm setting? How is uniformity of pattern?
