Team Check-point TC-1030 Instruction Manual page 18

This function divides the overall charge time
into four periods or "steps". The diagram at
right shows the total charge profile for four-step
charge mode, which is also what will show on
the charger's LCD. A maximum charge capacity
and charge current must be set for ALL FOUR
steps, as outlined in the diagrams below.

Step 1 - Getting Started:
1. Set the capacity value
to 33-50% of pack's rated
capacity.
2. Set a conservative
current, slightly under the
pack's 1C rating.
Setting Four-Step Charge
"
1. Press to find the Four-Step screen shown above-right.
2. The cursor will show next to the second line on the LCD. All settings on this line must be set to match the battery being
charged. Press the dial to highlight the number of cells, and rotate dial to adjust this value. To change peak sensitivity or
maximum temperature values, press
Press the dial to confirm all settings for this line.
3. Rotate the dial to move the cursor down to the capacity line (just under the graph). Four different capacity values are
shown, each being the maximum capacity that will be delivered to the battery during each of the four steps. The
capacity value for each step must be set:
a. Press dial to highlight the capacity value for step #1. Rotate dial to adjust this capacity value as needed.
"
b. Press to select the capacity for steps 2, 3, and 4, and set the capacity for each step accordingly.
c. Press dial to confirm all capacity settings.
4. Rotate the dial to move the cursor to the bottom line, which shows the four different charge current values which will be
delivered to the battery during each of the four steps . You must set the charge current value for each step:
a. Press dial to highlight the current value for step #1. Rotate dial to adjust this capacity value as needed.
"
b. Press to select the currents for steps 2, 3, and 4, and set the current for each step accordingly.
c. Press dial to confirm all capacity settings.
In step 1, it's important to stabilize the condition of the battery, so a conservative charge current should be set. Once the
battery is stabile and well into the charge process, much higher current can be delivered in step 2. The high current in step 2
may eventually heat the battery, so current in step 3 should be reduced. Lastly, it's best to reduce current in step 4 to again
stabilize the battery for the most accurate peak detection (fullest charge). Remember that the peak detection circuit
functions ONLY in step 4 (not steps 1-3).
During charge, the charger automatically moves from one step to the next once the capacity setting for each respective step has
been delivered to the battery. Be careful not to set the capacity value too high - especially in steps 2 and 3 where the current settings
are higher. The higher the capacity setting for any step, the longer that current will be applied to the battery during that step, and the
more likely the battery might overheat causing the temperature sensor to trip and stop fast charge completely.

Step 2 - Delivering Punch:
1. Set capacity to 50-75%
of pack's rated capacity.
2. Set a higher current, up
to the battery's 2C rating to
deliver "punch" for racing.

Step 3 - Avoid Heating:
1. Set capacity to 75-100%
of pack's rated capacity.
2. Reduce reduce current
below the value in step 2
(~1.2-1.5C) to prevent
battery heating.
