Hi, we are trying to build a 2S battery charger for a nano non-military drone. Taking the TIDA-00982 as a reference.
For adapting to our requirements:
1. We have merged battery in and balancing and protection port into a single connector which is used on our drone.
2. We have also increased the charging current to 4.5A
Seeking a validation of the design methods before we put into production.
Attached are the design schematic and board files.
