Battery charging circuit

The battery switch contains a simple battery charging circuit designed for 2S Li-XXX without balancing. The charging may be optionally enabled to keep the backup battery (B2) always ready without needing to remove it from the model (however, we recommend charging the battery with a balancer at least once a month). Several safety conditions are used during the charging:

  • The B1 voltage must be higher than the B2 voltage and the B1 must be selected/indicated by the LED.
  • The B2 voltage must be within the specified limits (5.5–8.3 V for LiPo/LiIon; 5.0–7.1 V for LiFe).
  • The T70 never charges to a full capacity.
  • The voltage difference must be lower than 5 V.
  • The temperature must be below 70 °C.
