Battery Jackery Explorer 100 Plus: only seems to yield about a third of the promised capacity

[adingbatponder]

The Jackery Explorer 100 Plus does not, like most other battery packs, switch off automatically when the power drawn is low, like that of a Meshtastic node. So should be very good for running nodes for many days (100 Wh is where its name comes from, but 96 Wh is specified on the battery.)

The Jackery Explorer 100 Plus battery pack seems to drain flat prematurely - only about a third of the listed capacity was available for 0.5 W load: why ?

I have 3 Explorer 100 Plus batteries. None of them, when showing 100 and fully charged, run a low power device (0.1 A at 5 V = 0.5 W) for more than about 2.5 days: and instead run totally flat suddenly after showing they had run down to about 68%. A power meter shows that the battery shows 0 after only having drained by about 35 % or so or 30 Wh: asolutely nothing like the 96 Wh specified. The node device tested should have run for at least 6 or 7 days but last only 2.5 days.

A total mystery as to what the Explorer 100 Plus is doing. Pressing the only button for 15 seconds to cause a reset makes no difference.

I cannot know if:

(a) the Jackery Explorer 100 Plus really drained flat after such a short time and is not 96 Wh after all, or

(b) the battery management system of the Jackery Explorer 100 Plus has come to a premature conclusion that the thing is empty and switches it off erroneously when it could carry on twice as long.

I have contacted Jackery about the accuracy of the figure of remaining percentage capacity shown, and they refused to advise on how to calibrate the display, whether to reset when full or reset when empty. No statement despite my asking many times.

So I am forced to believe the display (following reset when showing 100 capacity) shows the true remaining capacity (to about 6 % accuracy): and the Explorer 100 Plus for my Meshtastic application fails to deliver the certified capacity of 96 Wh but switches to show 0 after only about 35 Wh. That is a BIG margin.

It would be great to know if anyone else gets this behaviour too. Thanks.

I have two and have never seen this behavior with meshtastic or my Starlink mini

Which node are you running and how long does it run for on a 100 % charge?
