<p><b>New page</b></p><div>Hi!<br />
<br />
I have 3 stacked X-UPS1 boards. However, I seem to be unable to draw more than ~3A (12V) power output. When the combined power output rises, the "power loss detect" light starts intermittently flashing on the bottom board (not others), and the bottom batteries do not charge fully.<br />
<br />
The PSU is enough, I have tried with 1, 2 or 3 combined 5A/12V PSU and it's the same result.<br />
<br />
I think it is the 3A charging limit protection kicking in, but with stacked boards, it should be split among all boards?<br />
<br />
I've also observed - when running on battery, only the bottom board batteries lose charge. Measured with multimeter, the 2 top boards batteries keep ~4.2V charge, but the bottom one slowly drops - observed 3.5V while the top boards were still charged. Should all batteries on all boards discharge evenly?<br />
<br />
