3.2.1. Preparing the Rechargeable Battery

You must charge the rechargeable battery to the level set by the specified charger before using it with the the Drive-on-Chip Design Example.

Intel tuned the state-of-charge estimator for the Turnigy Accucell T100 battery based on experimental results at room temperature.The state-of-charge estimator does not give accurate results with other battery types. Natural battery variability, temperature or changes in the specification of the cells used by the manufacturer may also affect accuracy. You must use the battery only within its recommended operating range. Intel recommend you keep the state-of-charge above 10%.

  1. Make a converter using a HXT 4mm connector and the XT60 charger connector.
