Appendix
Appendix A: Recommended Parameters
Recommended parameters for specific battery types are given in ​ Appendix B​ . General settings are listed
below.
A.1 General Settings
Recommended generic settings can be found below. These settings assume LiFePO4 batteries. They can be
used as a starting point.
Capacity configuration:
Parameter Value Units
Designed capacity
This should be the rated capacity of your
battery in milliamps (multiply the
amp-hours of your pack by 1000)
Examples:
50 Ah pack: 50000
60 Ah pack: 60000
100Ah pack: 100000
200 Ah pack: 200000
280 Ah pack: 280000
mAh
Cycle capacity
This should be roughly 80% of the value
above.
Examples:
50 Ah pack: 40000
60 Ah pack: 48000
100Ah pack: 80000
200 Ah pack: 160000
280 Ah pack: 224000
