2.1.4 Wiring for live Li-Ion battery cells
2598C-AVR-06/06
Figure 2-3. CONN2 wiring and jumper settings for battery simulation
Table 2-4. JB3: Cell voltage simulation jumper block
Normal cell wiring is shown on the SB100 board, labeled as such. The ATmega406
supports from two to four stacked Li-Ion cells. As many cells as required may be
connected in parallel. A jumper should always connect CELL1- (CONN2 pin 8) to
Sense Resistor High (CONN2 pin 9) to enable the current-sense resistor. Cells
should always be connected on the lower positions first. The FET connection
(CONN2 pin 3) should be tied to the most positive cell connection (either CELL4+,
CELL3+ or CELL2+).
When using live cells, all jumpers should be removed from JB3. Additionally, the
sense resistor should be connected to the CCADC inputs by shorting JB4 pins 1-3
and 2-4. It is possible to use the Current Simulator while connected to live cells simply

When using live cells, never leave the system unattended due to the potential
hazards associated with the use of Li-Ion cells. Do not apply high charging or
discharging currents to the cells until you have verified that all safety systems,
both hardware and software, are functional under the specified conditions.
