Part Number: BOOSTXL-BATPAKMKII
I am developing an app using the MSP430FR5994 Launchpad and the Boostxl_BatpakMkII module.
My query relates to the use of a larger capacity 6000mAh LiPO cell, as the supplied cell and example software relate to a 1200mAh LiPO cell.
If I use a PC USB port for charging, I will still be limited to the current capacity of the USB port (500mA) , so can I retain all the default hardware components (related to charge limit/charge current) if using this larger capacity cell?
Apart from taking longer to charge, are there any issues with charging a LiPO battery at less than 0.1C rate?
What about firmware settings for the fuel gauge IC?
The example code for the BoostXL-BatpakMKII has include file HAL_BQ27441.h which defines the cell parameter requirements for the fuel gauge chip.
These values relate to the Design Capacity (1200mAh), the terminate voltage (3200mV) and the Taper Current (115mA).
I can change the design capacity to 6000mAh, and retain the terminate voltage as 3200 mV, but what about the Taper current?
I can not find any definitive specification of establishing what I should set this to for a 6000mAh cell I wish to use.
Can anyone provide some feedback on this parameter please?
