I can also now confirm that my 45watt USB-C wall charger will only charge this to 86%, but my Macbook Charger that is 87watts is good enough to get it to 100%.
I have no clue how many people seriously claim to be experts here and just present opinion as fact over and over.
Personally, I've tried to avoid LiPoly for going on close to 20 years.
They have way too many downsides compared to Lithium Ion, starting with the fact that they are even less shelf stable.
It also doesn't sit well with me that they're incorrectly telling people to "calibrate" the battery by fully depleting it.
Remember, people: Lithium based batteries do not have a memory effect and thus can't be calibrated through power cycles.
All you're doing by depleting it fully is stressing the battery, which actually causes it to not hold a charge as well.
It's common for batteries in a pack to have different states of charge (e.g. 4.05v, 4.12v etc). In those situations it's common to rebalance individual cells to bring the voltages in sync either by top balancing or bottom balancing cells.
A lot of Battery Management Systems have an automatic rebalancing algorithm that will do a bottom balance when you discharge the pack below 10%. Because this pack has discharge protection, 0% on it's gauge is likely just the threshold where it cuts off but isn't truly depleted. And discharging to 0% would trigger the bottom rebalancing.
It's also possible this is cheap Chinese crap and will burn your house down.
