Will the battery only supplement the power supply when the system load exceeds the set ILIM?
Can the lithium battery supply power when there is no solar input?

Hello,

1. The battery supplements the input source when VSYS falls below VBAT by VBSUP1 (40mV). This typically occurs when the combined system load and charge current exceed ILIM.

2. Yes, when there is no input source present, the battery discharges to supply the load on SYS.
