Mophie Launches Juice Pack Charging Cases for iPhone Air and iPhone 17 Pro
The charger in use is the SLM6900, which has this store. The translated datasheet is here. My board will flow as follows: USB-C ⇾ 5 V to 12.6 V boost circuit ⇾ 3S charging circuit --> battery Here is the 5V ⇾ 12.6 V boost schematic Here is the 3S charger circuit Below is the full schematic Another option I found is this product SLM6803.

How would I go about simulating a charging battery in LTSPICE? I've seen these two articles (A Tutorial on Battery Simulation - Matching Power Source to Electronic System and Accurate electrical battery model capable of predicting runtime and I-V performance) but the models there seem to be more geared towards circuits that are currently being ...
How do I calculate the approximated time for the Charging and Discharging of the battery? Is there any equation available for the purpose? If yes, then please provide me.
You would find the datasheet for the charging chip and use that to determine the appropriate pin. The physical size for the replacement resistor is the size that matches the resistor that's already on there. I don't recommend modifying a board from Amazon/ebay/alibaba. Unless you can reverse engineer the schematic and check that against the chip's datasheet to verify that it will perform ...
