A circuit board to charge a LiPo battery?

Click For Summary
SUMMARY

The discussion centers on charging a 7.4V 5000mAh 45C RC LiPo battery using a TP4056 circuit. Participants clarify that the TP4056 is unsuitable for charging multi-cell LiPo batteries due to its inability to balance cells. Instead, a dedicated balance charger or a BMS (Battery Management System) designed for 2S LiPo batteries is recommended. The conversation emphasizes the importance of using the correct charger as specified by the battery manufacturer to ensure safety and efficiency.

PREREQUISITES
  • Understanding of LiPo battery specifications, particularly 2S configurations.
  • Familiarity with TP4056 charging circuits and their limitations.
  • Knowledge of battery management systems (BMS) for multi-cell batteries.
  • Basic electronics skills for integrating charging circuits into projects.
NEXT STEPS
  • Research BMS options compatible with 2S LiPo batteries.
  • Learn about safe charging practices for LiPo batteries.
  • Investigate dedicated balance chargers for multi-cell configurations.
  • Explore Arduino projects that utilize LiPo batteries for power management.
USEFUL FOR

Electronics hobbyists, RC enthusiasts, and makers working on projects involving LiPo batteries, particularly those integrating Arduino components and requiring safe charging solutions.

Hi guys I'm creating a prop that's probably going to have a 7,4V 5000 mah 45C RC Lipo battery in it, and I'm planning to keep it permanent in the prop with a charge circut to charge it up with usb perhaps.

I've thought of using a tp4056 circuit I have laying around and it seems like the internet says it won't work, I have limited knowledge in this but I'm learning more everyday! So far I've read is that I need something that can balance out the about three cells it has? and that this might do the job, is that true? http://www.all-battery.com/PCB74vli-ion2S_32175.aspx

If not, can you guys recommend me one that will work well with my battery or advise me to do it in another way perhaps?

Additional information:
So far it's going to charge a Arduino nano, Arduino H bridge, 1 RGB led 5v, 3-6v DC motor, 3 x Servos 4.8V
