charger)

Balance charging cannot be done through the
transmitter, you must remove the LiFe battery to do
this charge.
Charge the optional FT2F1700BV2/2100BV2
(LiFe) battery with the special charger in accor-
dance with the instruction manual supplied.
When the battery will not be used for a long time,
to prevent it from deteriorating we recommend
that it be kept in about the half capacity state in-
stead of fully charged. Also be careful that the bat-
tery does not enter the over-discharged state due
to self-discharge.
Periodically (about every 3 months) charge the
battery.

The transmitter charging circuit is equipped with an over cur-
rent protection circuit (1.0A). If the battery is charged with a
quick charger for other than digital proportional R/C sets, it
may not be fully charged.
The charging time when charging the HT5F1800B battery
with the optional special charger is approximately 15 hours.
However, when the battery has not been used for some time,
repeat charging 2 or 3 times to activate the battery.
