Does pass-through charging reduce the battery life more than separately charging and using it?
Hello,
the FAQ says: "Do Jackery portable power stations support pass-through charging? Yes, except for the Explorer 160, all other products support pass-through charging. But we don't suggest using it this way very frequently as it will reduce the battery life."
As far as I understand the Jackery can not bypass the battery and send the power from the solar panels directly to the output, even if there is enough energy available at the panels.
So the energy always goes through the battery, which obviously reduces the lifetime, because the battery is being used.
Example with the Explorer 500: Day 1: I charge the battery for 10 hours with 50 Watt, disconnect the panels and then use the battery for 10 hours (1 cycle used) Day 2: I charge the battery for 10 hours with 50 Watt but use those 50 Watt in the same time on the output (1 cycle used?)
I assume, on day 2 the battery might get a bit hotter and therefore suffer a bit more...
Does someone know, if and how big the difference between day 1 and day 2 would be?
Thanks in advance!
Jackery states it will harm the battery... for some reason and won't disclose why or how much. Just that "you should not do this" and "our technicians don't recommend it". They refuse to provide information on the impact yet they continue to advertise pass-through charging as a big deal.
Seriously considering refusing my 2000 and 4x 200w panel delivery next week based on this, and switching to the Bluetti 200. Right now the only thing holding me back is the portability of the Jackery and the better quality.
It really shouldn't matter, and I don't know why Jackery doesn't recommend it. For what it's worth, I've been using an Explorer 240 as a CPAP UPS for about a year, now, and its capacity does not seem to be diminished at all.
The idea that the battery would be bypassed is counterintuitive.
I believe your interpretation is right, and the use of "pass-through" is wrong. It should be: being able to charge both batteries at once.
I think the idea of bypassing the battery is a good one. But is that how it happens? I guess not. If the device were to pass current past the battery when it reached 100%, it would prolong the battery's life. But we waste the battery's life, and then we recharge it....

The idea that the battery would be bypassed is counterintuitive. Why have a battery at all then?

I notice that when charging my ebike battery with pass-through (and solar panels), less of the jackery juice is used compared with just using the jackery directly. So, the idea that BOTH batteries are being charged seem to make sense. I'm hoping that since less is demanded from the jackery, it's not a full cycle discharge.
I agree that it would be nice if jackery explained why they discourage pass-through since it is something they advertise!!
