Great video, thanks. I stumbled upon it as I'm considering buying one (possibly two) Cellink Neos. Worrying that the workmanship on the connectors isn't great - these aren't cheap units. A great little tip I've picked up from the RC car community when soldering on XT90 or XT60 connectors is always have the new plug connected to its opposite connector (a spare, not anything live), this will avoid the connectors deforming from the solder gun heat. These connectors do take some heating up to solder properly.
Just slightly heat up the cover with the batteries( the heat from a hair dryer will do, its just double sided tape holding the cover the the batteries, and only a small area of the round batteries is making contact so it doesn't take much heat ), and the cover pops off. You will need to un solder the six battery tabs from the circuit board before you can find the bad cell ( unless you're replacing all), just one bed cell with shutdown the system. The same tape thats used for on the cover is also used to hold the batteries to the circuitboard. The batteries are easily accessible ( LFP26650E 3.2v ), you can get them with the tabs or without. Invest in a tab welder ( they're very cheap, just practice welding tabs on old batteries). I don't feel comfortable welding battery tabs inside the house ( i've never had an issue with a battery blowing up, but you never know ), but definitely don't try to solder the tabs to a battery, the heat will destroy the battery before the solder even melts, a cheap tap welder will make these repairs much easer. Finally solder the tabs back to the board ( just make sure that you noted each cell's polarity before you start taking things apart). I've fixed three of these battery packs already and they're still going strong, good luck. I know this question is quite old, but figured that someone else can use this info, tnx.

Can you please make a video how to replace inside battery Cellink thanks
