I want to use Hugo 2 in DAC only mode to bypass it's amplifier section as I want to use Topping A90 is line out mode same as DAC only mode or there's some other sequence.
Two things to note; it's heretical to speak about the Hugo 2 having an amp section. Second, punctuation is your friend.I want to use Hugo 2 in DAC only mode to bypass it's amplifier section as I want to use Topping A90 is line out mode same as DAC only mode or there's some other sequence.
From the Hugo 2 page @ Chord Electronics:I want to use Hugo 2 in DAC only mode to bypass it's amplifier section as I want to use Topping A90 is line out mode same as DAC only mode or there's some other sequence.
You can't bypass its «amplifier section» – both headphone output and line output are directly connected to the DAC's analogue output stage. You can just add another amplification stage (for whatever purpose). And there's no «DAC only mode», just a volume preset to 3 volts max.I want to use Hugo 2 in DAC only mode to bypass it's amplifier section as I want to use Topping A90 is line out mode same as DAC only mode or there's some other sequence.

Can you show me a post where he has been wrong?@JaZZ is right here,
This I cannot do.Can you show me a post where he has been wrong?
Those batteries are ligitmate. I opened my Hugo 2 and my batteries are exactly the same. My Hugo 2 was bought new from Audio-T in the UK.
I have taken a couple of pictures of inside my Hugo 2. Long story, had to open it anyway, so today seemed like a good idea to do it now. (What with all the battery talk.)
I could not get a complete picture of the battery label, but there is enough to show which battery. I could not get a complete picture of the battery label, because the batteries are stuck to the case. If you look under the word 'capacity', on one of my pictures, you can see the adhesive. I rolled the battery to see the label, but didn't want to move it further. I wanted the battery to still be stuck and it is, when I rolled it back into place. If I had pulled it off further, I could not be sure the battery would have re-stuck.
Anyway my pictures:
In this last picture you can see enough of the label. It can be identified as the same in the picture I got from the internet today. The one at the top of this post. That picture has the complete label.
My pictures confirm the 3350mAh battery. My battery life was 7.75 hours when new. Also note the connectors on them.
Has anyone replaced their Hugo 2 batteries with either of the above cells with long term or short term use? I am based in Canada and therefore somewhat reluctant to order a BF cell from Hong Kong, while the B cell is available readily in the country from reputable sellers.
Thanks for reading, friends, and stay safe

Why not just get the correct batteries from Chord or your dealer?
One thing I've noticed with my Hugo 2 is that the USB data cable is quite easily dislodged by even minor movement, meaning that sound is then cut off. Anyone else have this issue?
I am pretty sure that the chord batteries are not nickel cobalt, and lithium based instead.It's over an order of magnitude cost difference, especially in Canada: The last relevant quoted price on this thread was $375 USD. The cost of the NCR18650B cells is approximately $35 CAD for the pair, and I am an experienced hand with electronics/soldering work. It would be an appropriate use of my skills if I can find the correct cells and save a considerable amount of money (to an undergrad student)

Email support@chordelectronics.co.uk and check with them before you buy any batteries.
The $375 that you quote is probably the price for the service centre to fit them, so it should be much cheaper if you diy.
To anyone who has successfully replaced Hugo 2 batteries, I have some follow up research/questions:
To recap, this is the most detailed description of the batteries on this thread, which identically matches my unit as well:
Also, there is a twitter post by Fidelizer Audio which matches: https://twitter.com/FidelizerAudio/status/1303888858879152129/photo/1
I am tentatively inferring the model number as:
PNCRBF18650-1S1P => P-NCR-BF-18650-1S1P
P = Panasonic
NCR = Base battery chemistry (Nickel Cobalt)
BF = Model demarcation
18650 = Physical size, of which we are already certain
1S1P = Single cell series, single cell parallel, which we have also agreed upon
Options that closely match the info above (worst to best):
Panasonic/Sanyo NCR18650GA: https://voltaplex.com/panasonic-sanyo-ga-18650-battery-ncr18650ga
The spec that stands out to me is the 10.0A continuous discharge rate. The max peak current output on the Hugo 2 is less than 1A, and I am certain that the rest of the electronics cannot use anywhere close to 18A continuously. I think this one is out of the running.
Panasonic NCR18650B: https://voltaplex.com/panasonic-b-18650-battery-ncr18650b
This seems to be appropriate. The size of the battery is very close to the space limitation inside the Hugo 2, however, Even with added padding for the anode/cathode covers it seems like it would fit. I've also seen this specific cell in a sale ad on head-fi as a replacement cell, but not confirmed installed and working inside the Hugo 2.
Panasonic NCR18650BF: https://voltaplex.com/panasonic-bf-18650-battery-ncr18650bf
Almost identical to the B series above, however, it is "intended for use in high capacity battery packs". I have yet to hone in on what that actually means. Spec wise, it is almost identical to the B series, aside from slight differences in chemistry and weight.

Last time I had my Hugo 2 open I made measurements of the original Chord Electronics batteries. (The batteries that shipped with my Hugo 2.) The 18650 batteries come in different diameters so you need to know the diameter of the batteries you can fit. Bear in mind that the fitted Hugo batteries leave no space. They make an indent in the pad on the top cover of the Hugo 2.
Below is my finding having used one of those digital measuring things. Can't recall the name.
XH 2.54 plug (I think this is the plug that fits the Hugo 2 board.)
my battery 68mm (length)
gap on Hugo 2 board 72mm (length)
diameter 18.4mm - battery does make an indent in the pad on the top of the Hugo 2. (However it might fit an 18.5mm diameter battery.)
E.g. there is a 19.1mm on Farnell, at 3500mAh. That would not fit.
