How I Charger Works
After setting up the desired battery pack chemistry (Life, Lion,
LiPo) via a small slider switch, you simply connect a 12 volt power
supply to the I Charger.
Once power is applied the charger will:
1) Automatically enter a battery precondition mode where it tests
the battery voltage. If the battery voltage is low the charge current
is reduced to 15% of the programmed maximum and applied until
battery voltage reaches 70% of expected fully charged float volt-
age.
2) Once the battery voltage reaches 70% of the expected fully
charged float voltage I Charger automatically increases maximum
charge current to the full charge value (up to 2A).
3) I Charge will then charge the battery pack at full current
(up to 2A) until expected fully charged float voltage is reached.
4) At reaching expected fully charged float voltage, I Charge
reduces high charge current proportionally as the battery internal
resistance increases.
5) At 90% of capacity (C/10) the battery charge algorithm enters a
trickle charge state and will stay in the trickle charge state for up
to 3 hours. This allows a battery charge state to reach the 100%
capacity. NOTE: Most hobby chargers end at 90 - 95 % of actual
battery capacity. I Charger will take the capacity all the way to
100%.
6) If less than 97.5% of capacity is reached after the 3 hour period
then I Charger re-initiates, and charging continues for another full
cycle. This means you are guaranteed to know that your battery is
fully charged 100% at all times as long as power is connected for
the appropriate amount of time.
7) As long as power is supplied to the charger the I Charger will
monitor the battery voltage and if the battery voltage falls below
2.5% of the fully charged float voltage the charge cycle will start
again. This means you can leave I Charger theoretically connected
and permanently powered on to keep the battery topped up.
PLEASE NOTE: While we have designed I Charger with the up
-
most in safety a permanent power connection is not advised.
Also some battery chemistries do not react well to having a
100% charge all the time.
