I recently bought one from their official indian webstore with the sole intention to rip the batteries out. I pried it open and I can confirm that this powerbank model cannot be opened without permanently damaging the cover. Once you open you cannot put the cover back on. It was sealed with clips, all of which face inwards and break if someone tries to open it. Guess they never wanted anyone to open it, more like a one time factory close sealing .It took some effort to take the cover off with the tip of a large knife. The cover will also get deformed due to this.
Batteries inside are definitely genuine LGABF1L11865 model. This powerbank costed only as much much as 2 of these batteries sold in retail. Wow!! 6 batteries for the price of 2.
Batteries were soldered in parallel with a thin tape shaped sheet of metal. Took that off with some force. Charging board also had a thermistor to monitor battery temperature. I’m gonna salvage that component.
