Kenneth Ransom, N5VHO has plotted the battery min/max for the last 8 days. We
see that the battery voltage is decreasing at a faster rate than expected.

Ken's plot is extremely valuable. It strongly suggests battery failure,
not a negative power budget as Tony,

How about you designing circuitry/program to charge cells individually

That's a great idea; I wish I thought of it first, but it was Lou

Dear Gould / ARISSat-1 team,
Thanks for sharing this !
When the battery would go dead (or has very long charge times),
to what extend would that also impact the low power mode ?
Better phrazed: what are the requirements to go/stay in low power mode ?
Is there a (no power) mode, where there
