LG 18650 HB4 1500mAh (Yellow)



Official specifications:

• Maximum Capacity: 1500mAh
• Nominal voltage: 3.60V
• Discharge end voltage: 2.50V
• Standard charge current: 1.25A
• Maximum charge current: 10A
• Maximum continuous discharge current: 30A

This is an older high current cell.










The discharge curves tracks fine and it can nearly constant capacity up to 30A, but the output voltage is a bit low at 30A.



















Due to a mistake I used the low current program for one of the cells, this means 0.5A charge current and protection test only up to 7A, discharge currents are the same, except the low current program also includes a 0.1A discharge current.


Conclusion

This looks like an upgrade to the HB2 cell. The high current performance is good, but the capacity is low by today's standard.

Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
