Hello folks
I'm Helmut from Austria!
My project is a 48V 280 AH battery block for an electric boat with 8KW drive
I ordered 280Ah cells from Shenzen Basesn and a JBD BMS, the relay version.
The cells was prompted as Grade-A+ brand new.
Delievery and customer clearance was as promised
A visual check revealed that a few cells are slightly swollen see photos.
Voltages of the cells are all exactly the same 3.295V
Internal resistant are 19 and 20 mOhm
Qr-Code looks good and buildingdate would be from end of 2021 and begin of 2022
I would like to clamp the cells with 300Kgf according to the specification and now I thought with my 16s configuration I have 2 rows so I would make sure that the 2 rows are each equipped with bloated and flat cells so that the package length is the same.
I would be grateful for tips and suggestions HowToDo!
Is this slight flatulence normal?
Pic1 shows the cells staing each next to other
Pic2 shows the pack with sorted cells and compressed
Pic2 shows the QR of one cell, looks that good?
