Jumper JU1 connects the thermistor input (THERM) to
GND through a 10kΩ resistor, disabling temperature
qualification. To enable temperature qualification
(charging between 0°C and +50°C), remove the shunt
from JU1 and connect a thermistor (BC Components
part # 2322-640-63103 or equivalent) to the THERM
and GND pads. For more information, refer to the
MAX1757 and MAX1758 data sheets.

FUNCTION
The EV kits can be placed in shutdown mode using
jumper JU2. (See Table 1 for jumper settings.)
Jumper JU3 selects the number of series cells to be
charged. (See Table 1 for jumper settings.)
