Disclaimer: The tested EVE INR21700 40PL sample is most likely still a pre-production sample. This one has been disassembled from the customer battery pack. I only got this sample through sheer fortune and the support of the ES community.

Test setup:
- EVE 40PL sample was dressed into standard shrink tube with plastic isolator on the positive terminal.
- ca 5.5 mm^2 cross-section copper strips (11 mm wide with a thickness of 0.5 mm) were welded with the use of Micro-TIG welder to all three competitors (Molicel P30B, P45B and EVE 40PL)
- 6 mm^2 (power) and 0.5mm^2 (sense) Cu wires, ended witch cable lugs with M5 screw, were used for 4-Wire connection with the battery tester.
- Only EVE 40PL is shown as example.
