It’s hardly comforting when you notice that the capacity of your transmitter battery is clearly declining, and its self-discharge rate is so high in any case.
The LiPoTx is the answer, as it is a replacement battery which fits in the existing transmitter battery compartment.

• Integral balancer
• Integral safety circuits, to ensure - as far as possible - that the battery and the transmitter cannot
  be damaged by incorrect charging (e.g. Ni-Cd program is used).
• Simulation of declining Ni-Cd battery voltage to provide compatibility with existing battery voltage indicators.
