STEP 1 SOFT START
A preliminary charge processes that gently introduces power to the battery. This
protects the battery and increases battery life.
STEP 2 BULK
Charging with maximum current until approximately 90% battery capacity.
Bulk mode for the charging cycle. The start phase continues until the battery's
terminal voltage has risen above the set limit, at which point the charger
switches to bulk charging. If the terminal voltage has not passed the voltage
limit within the time limit, the charger switches to fault mode (Step 2 lamp solid)
and discontinues the charging. If so, the battery is faulty or its capacity is too
large.
STEP 3 ABSORPTION
Charging with declining current to maximize up to 95% battery capacity.
STEP 4 ANALYSE
Tests if the battery can hold charge. Batteries that can not hold charge may need
to be replaced.
STEP 5 COMPLETION
Final charge with increased current.
STEP 6 MAXIMIZATION
Final charge with maximum voltage up to 100% battery capacity.
STEP 7 FLOAT
The Float stage maintains the battery at 100% charge without overcharging or
damaging the battery. This means the charger can be left connected to the
battery indefinitely.
STEP 8 MAINTAIN
Maintaining the battery at 95–100% capacity. The charger monitors the battery
voltage and gives a maintain when necessary to keep the battery fully charged.
The 12V AUTOMATIC LITHIUM BATTERY CHARGER has an 8-step fully
automatic charging cycle. the cycle is repeated infinitely. If the terminal voltage
drops below a lower limit, the charger automatically goes back to the beginning
of the charging curve.

13. PERMANENT WIRING TO BATTERY
It is possible to hard wire the DC charging leads to the battery for permanent
installations.
You will need 2 x ring terminals, an inline fuse holder and a fuse with a rating
equal to or more than twice of the chargers output. (See below)
5A = 10 Amp fuse 7A = 15 Amp fuse 10A = 20 Amp fuse
12A = 25 Amp fuse 15A = 30 Amp fuse 20A = 40 Amp fuse
Connection:
1. Cut off the supplied battery clips; ensure you leave sufficient cable to reach
the battery terminals. (DO NOT extend the battery charger DC cables, as the
added voltage drop will cause incorrect charging).
2. Fit a ring terminal to the BLACK Negative (-) wire.
3. Connect the inline fuse to the RED Positive (+) wire.
4. Connect a ring terminal to the other end of the inline fuse.
5. Connect the RED lead (with inline fuse and ring terminal) to the Positive (+)
battery post.
6. Connect the BLACK lead (with ring terminal) to the Negative (-) battery post.
7. Fit the correctly rated fuse.
If the charger is used in a Permanent / Hard Wired application and the vehicle
will not be used for some time, it is best to leave the charger connected to
mains power (turned ‘On’) so that it can maintain the battery fully charged.
Ensure any modification to the 110V/220-240V AC mains lead is carried out by
a qualified person and that connection to supply mains is in accordance with
National wiring rules.
