RC Drone Charger Development

I'm looking for an experienced electronics engineer to develop a balance charger and discharger specifically for RC drones. The charger should support LiPo and Li-ion batteries, with a maximum voltage of 16.8V.

Key Requirements:
- Balance charging and discharging functionality
- Support for LiPo and Li-ion battery types
- Maximum voltage support of 16.8V
- Suitable for RC drones
- The user should be able to select the battery type, battery cells(1s,2s,3s,4s), calibrate voltage, modes such as quick charging/balance charging/discharging/storage charging.
- The user should also be able to select the current.

Ideal Skills and Experience:
- Expertise in battery management systems
- Expert in RC battery such as LiPo and Li-ion battery
- Knowledge in embedded systems
- Knowledge designing custom micro-controllers is a plus
- Knowledge in arudino
- Experience with RC vehicle charging systems
- Knowledge of safety protocols and regulations
- Strong circuit design and prototyping skills
