would this be just plug&play ? sorry i’m a total noob into device openings and whatnot…

edit : which connector is the right one ? pico lock or the other type ?

Oh my god! Lmao, where were you a week ago!

Atleast I learned something new. And I probably got a safe branded battery that I know what it is (from LG, the Korean company).

@mbirand
But yeah it is almost plug in play. From that link, you need the one listed in the drop-down box as "PR-CU-R648 - JST-PH". That JST-PH plug is the 2pin ribbon plug.

Then you would need to pull out the red wire in the plastic part and swap it's position with the black one.

Here is a picture of the original protection unit of the Hugo2 original battery.
Notice the red wire is in a different position compared to the plug in the link above.

Copy the plug in this picture .
Should be as easy as lifting that plastic tab, and pulling out the positive red wire.

Oh and you'd still need thin double-sided tape to stick the new battery in place: iFixit Tesa 61395 Tape - 2 mm https://a.co/d/9JYi1tW

Lol! Quoting my old post.

Just wanna give an update on the battery swap. I ended up going with this battery. I could have gone with this with more capacity but I'd have to pay extra shipping due to that it is not UN38.3 tested ($44 per package; may be worth it if one decided to stock up these batteries). I have about 1hr longer battery life with the new 2600mah battery. The old battery I swapped out looks identical to the one sold in UK. I teared open the blue wrap. Underneath is a red wrap with no branding on it. Underneath the red wrap is the actual silver 18650 battery, still with no branding on it. I'd assume at some point Chord decided to ditch the Enix-Engery battery and went with a generic one.

The process is entirely tool-less, except for an allen wrench to open up the Hugo 2. I had to flip the JST-PH connector by opening it up with my finger nail, like @masahito24@chart had mentioned. Not sure who is the one not adhering to the standard here, Chord or Battery Space.



One can technically 3d print an external "battery cage" for Hugo 2 to make the battery swap even more accessible, like swapping out the AA battery from a walkman in the old days. You'll need a JST extension cable, possibly running it through a hole drilled on the bluetooth plastic window.

You can definitely leave a message in your order asking them to flip the connector for you, since the entire battery pack was custom built.
Here are two comprehensive measurements of 18650 batteries. MJ1 really is a solid choice for low amp usage.

Would someone be kind enough to post the mapping of the volume levels/colors to the output voltage?

 

[FooFighter]

Sorry, wrong thread

Long-press ON and X-PHD to get to 3V.

Use the remote to back off 5 clicks for approx. 2V.

Note colour for future reference.

And if you are getting clipping at around 3V, and it is not caused from your next device in the chain. Then probably time to replace the 18650 batteries in your Hugo2.

That seems how it went for me. I can use Line-out mode with no problem now.

Many devices only require 1V line in. Green is where I can park Hugo2's volume and not experience any clipping on KSE1200 (no pad)

were you getting clipping while on charge too or on batteries only ?

I just tried. Tool-less, these overspec'ed batteries work too. Keeppower is a named brand, whereas battery space is custom built in the USA. Pick your poison.

You need some JST to PH adapter, and some mental gymnastics to fit all those wires inside the Hugo 2. It is doable.

There's no need to flip the polarity with this one.

That one is a Li-Ion cell. It is recommended to stick with LiFePO4 (LFP) cells for safety from fire and explosion.

EDIT: scratch that - looks like the originals were Li-Ion so LFP might not give enough voltage.

 

[Infoseeker]

LiFePO4 only a concern if you don't know what you are doing.

that battery is already made for you and ready. Plug-n-play.

I thought the original ones were Li-Ion?

You're right. They were.
