Max Voltage is 3.65, these are ALL Overcharged and god only knows how long and if they are damaged as a result.
The odds are they got FROZEN during shipping as well and with a High Charge like that...
They should NEVER EVER be shipped at 100% SOC and in fact most carriers would reject that IF they new... It is NOT Allowed for ANY Lithium Based battery. It is a RISK Factor. Shipping Lithium Cells shoudl be at no more than 50%, in LFP terms generally 3.200V +/- 0.050
Fingers crossed that you did not get Phookered.
Juneng-Electronics and NOT a Xuba Tech email ? or an 163.com email address ? FISHY !
FYI, I am the originator of the LONG XUBA thread here and know something of them....
I would IMMEDIATELY send a message that they all arrived OVER-Charged at between 3.720 - 3.760 when they should have NEVER been shipped above 50% SOC. Opening Volley for a claim IF They are screwed up. THEY KNOW they are not supposed to ship above 3.200 volts.
