Cautions to observe prior to charging LiFePO
• LiFePO chargers are designed for charging
4
LiFePO (LFP) batteries only. Make sure you
4
have the correct battery charger for the che-
mistry and number of cells in series. If the
number of cells in series in the battery pack is
not known you can calculate it by dividing the
voltage indicated by 3.2VDC for LiFePO
12.8VDC LFP battery contains 4 LiFePO
Make sure the charge voltage indicated on the
charger corresponds to the number of battery
cells in series multiplied by 3.65VDC (e.g. a
4 cell LFP battery is typically charged using
14.6VDC).
NOTE: The voltages indicated above are typical
and may vary between battery types and battery
makes. If in doubt; consult the specifications for
your battery.
• Make sure the specifications for your battery al-
lows for the maximum charge current indicated
on the charger.
• Make sure the specifications for your battery
allows for the environmental conditions present
during charging.
• Never attempt to charge batteries that are not
rechargeable.
• We recommend that you connect the charger to
the mains before connection is made to the bat-
tery. This will reduce the sparks that may occur
due to difference in potential between charger
terminals and battery terminals.
NOTE! Make sure the charger terminals are not
short-circuited and ensure that the polarity is
correct.
• Please ensure correct polarity when connecting
to the battery terminals. Reverse polarity conne-
ction may, in some chargers (see the chargers
specifications), result in a fuse blowing, requi-
ring replacement or leaving the charger useless.
(e.g. a • The charge cycle starts when the charger is
4
cells). connected to the mains.

• If the charger is disconnected from the mains
voltage during a charge cycle the charger will
start a new charge cycle when it is reconnected
to the mains.
• The recommended minimum and maximum
battery capacity for which the specific charger
can be used vary from battery to battery. Plea-
se follow the datasheet and recommendations
from the battery manufacturer. In our tables we
use typical 2C as a maximum current for
LiFePO
4
a 1Ah battery should be max 2A. Thus the typi-
cal minimum capacity recommendation is 1Ah
for a 2A charger. For max battery capacity we
have used C/40 for chargers with timer (and/or
uC) and 100 times current detection levels for
chargers using only this termination method.
For a 2A charger with 0.2A current detection
level the max capacity recommended will be
100 x 0.2A = 20Ah. Again this is just typical re-
commendations. Please read recommendations
and datasheets from battery manufacturer.
