Fusion L702B Lithium Functions and Parameters, Charge Rate 2C TCS Capacity 90%

LITHIUM FUNCTIONS AND PARAMETERS

When a Lithium type battery is selected, the following functions and parameters are available. The 2nd and 3rd pages (shown below) are accessed by moving the line selection down arrow off the bottom of the page.

‘CHG.’ – CHARGE

This line shows the charge current and the maximum cell voltage which can be edited by press the ‘Enter’ button to highlight the parameter, then the ‘Inc’ and ‘Dec’ buttons to edit the value. The default charge current for a Lithium battery is set to 1C (1 x capacity), however this can be adjusted from 0.1 to 20 Amps.

N.B. For safety the charge current is limited to the capacity x charge rate (see Maximum Charge Rate setting). If you want to increase the charge current above 2C, you must first increase the maximum charge rate before you can increase the charge current.

Normally, the maximum cell voltage should be left at the default value (LiPo=4.2V, LiIo=4.1V & LiFe=3.7V), but in very cold weather a Lithium Polymer pack can be overcharged at 4.2V, so reducing the maximum charge voltage to 4.1V can increase the life of your pack.

Press the ‘Enter’ button for 2 seconds on this line to start the charge.

‘DCHG.’ - DISCHARGE

This shows the discharge current and the cut-off voltage per cell. Pressing the ‘Enter’ button for 2 seconds with this line selected will start the discharge.

STORE MODE START

It is recommended that Lithium batteries are not left in a fully charged or discharged state for long periods of time, especially when stored in a cold environment.
