I purchased the powerhouse 767 with the extra battery and the extra battery is not charging. I have been using the system for less than 2 weeks and it’s a complete fail. On Sunday, March 24, I update the firmware and the extra battery started to charge but today March 27, it stopped just like before. Now I have reached out to customer support but that’s useless. They asked for my shipping address, invoice to show proof of purchase, serial number and a video with the issue. I sent all this on Sunday and today they asked for the same information. Anker, this is bad customer service. I was told in one of the emails to use DC to power the battery and then switch to solar. I can’t do that since I only use solar. The video I sent showed that the solar panels and cable are working since I connect them to another battery and it was charging. Anyone, someone, what else can be done?
SolixF2000 extra battery is not charging
Hi! With issues like this that seem to be one-offs, it’s best to work with Support@anker.com. A ticket has been created and the right channels are involved or getting involved in the query. I appreciate that you took the time to reach out to support even though your experience has been less than ideal. Reports like this help us track product issues including problems associated with specific batches and in some cases, helps us identify user complications.
If you’re up for it, and you have a car, you could try DC charging that way. What this gains, I don’t know, but I wanted to suggest it as it might help you and if it doesn’t, you can report the detail to support.
It sounds like you have two expansions for the F2000 (fka 767), and one works while the other fails to charge. If that’s correct, my guess is that we’ll be honoring the warranty on the battery that’s not charging.
This is clearly not a one off. I have the same system (brand new with the latest firmware) and the extension battery will not charge from solar. It initially looks like it is charging but it soon gives up on the battery and only charges the main battery in the 767. I have tried at various different levels of charge for both the main battery and the extension battery. Each time the extension battery remains at exactly the same level of charge at the end of the day, but the main battery charges fine.
The extension battery charges fine with AC.
I have a 200W panel which delivers 20V and generally around 120W during my current camping trip.
I NEED the battery to charge from solar. That was the main purpose behind buying it. Please tell me you have found a solution. Thanks
Same problem with a brand new F2600, the expansion battery will not charge and now shows 0% on the Solix but lighted rings on the battery shows 85%
Update: I retried charging from solar after main battery was at 100%. Last time I tried, it did not continue charging the extension battery, but now it seems to be charging fine from solar.
It looks like the logic is to discharge the extension battery first, then the main, and recharge the main first.
So right now everything seems to be working 
I’m having the same issue. F2600 with Expansion battery. Expansion battery not charging after seemingly working OK for 48hrs. Charging with solar and Main battery is at 100%…
I’m having the same issues with my c1000 expansion battery. When charging via solar, the expansion battery will randomly stop charging and it will start charging the main battery even though it’s at 99% and will never switch unless i reset the expansion battery or unplug the solar and plug it back in. However this only works for 1% and then it switches back to the main and will stay that way for hours. The expansion battery never fully charging regardless of the main battery.
I hope Anker will solve this Problem. I want to use ist in my RV next summer.
My new setting is a f2600 since today (Before i had f2000) and expansion battery BP2600. I will try my setup when the sun is shining again in Germany 
Same problem here. Received my F2600 and external battery on November 11th and everything charged fine. Went to check the status of the unit two weeks later and the external battery showed zero percent charge and red on the app even though the ring light on it is fully white. Contacted Anker and got them to replace the external battery that arrived yesterday. Connected it to the F2600 and it showed charging with 6 minutes left to fully charge. After two hours plugged in, it still showed charging with 6 minutes left. Four hours later, the external battery icon is now red and the display on the F2600 is blinking as if the external battery is not working. The issue is obviously with the F2600 and not the external battery. Waiting to hear from Anker on what to do next.
OK, Anker got back to me and had me reset the F2600 by sticking a paperclip in the reset hole in the lower left of the display panel. That solved the issue of the external battery not showing fully charged. However, I noticed that the F2600 was down 2% in charge but was not charging even though plugged in. I turned the external battery off, unplugged the F2600, and did the reset again, and this time the F2600 began charging when plugged into the wall outlet. Once that was complete, I turned on the external battery to make sure both registered 100% and they did. Thanks Anker!
Thanks for the advice. Had the same issue and your instructions solved it in minutes.
Absurd!
Stick a paper clip in a hole? To reboot it or some such? Is there a magic chant and some candles I need to light also?
Fix it already Anker. Pathetic.
This is hardly the only design flaw; there a whole bunch of problems:
https://windinmyface.com/blog/2024/20241220_1958-Anker-design-flaws.html
And BTW, if the Anker is powering 4 or 5 computers and the paper clip thing is done, the thing is likely to cut AC power and take down a whole bank of computers.
Something like that makes it a toy, not a serious piece of gear.
BTW, the discharge behavior is the worst possible situation: draining the BP1000 or BP2000 to 1% charge before any of the main battery is used means that the lifespan and charge capacity of the external battery is greatly reduced. That is just how batteries work
The discharge cutoff should be programmable to not go below X% (eg 10 to 20%) so as to maintain the longevity of the batteries. For example, discharging the external and internal by 50% versus a full discharge of BP1000 will DOUBLE the charge cycle lifespan at the same reduction in charge capacity. Eg 80% capacity remaining at 6000 cycles instead of at 3000 cycles.
More to the point of the BP1000 or BP2000 failing to charge, it may be that this destructive discharge algorithm drains the battery so low that it enters a comatose state, and that’s why it won’t charge! In other words, Anker designed it to FAIL.
If I apply AC power (which I won’t have if using it as a system in the field with solar!) and the BP1000 then charges to 2%, then I cut AC power, then solar charging resumes. Something is very broken in the charging algorithm.
In other words, the highly destructive total discharge of the external battery not only massively degrades its lifespan, but also makes it fail to charge. And this is BY DESIGN.
Paper clip reset… AC power kick in the butt… these make it work once that time. The next day, it fails to charge the BP1000 all over again. And when you do get it to charge, the whiny oscillating fan noise will drive you crazy.
This thing is a disaster. I bought two of them (2 X C1000+BP1000).
One of them is for solar-only mountain cabin where there is no internet, no smart phone, no A/C power. For a relative who is 82 years old with a flip phone. The thing has to sit there and work, not require coddling for the most basic of functions—charging.
If this stuff cannot charge, it is just a boat Anker. It has to work and work all the time, with no resets or games to play.
Anker, where is your reply here? Where is a real solution? Where is a guarantee that your gear works?

Anker Support is clueless. There are NO solutions, no firmware update.
- Reset with paper clip fixes it once; the next day it repeats the bad behavior
- Brief AC charge also resets.
Both of these are useless for a system that has to work whether home or not, and totally defeat the purpose of a solar generator.
After extensive back and forth, Anker support has NOTHING to offer, and has not acknowledged the issue for the severe bug that it is, which IMO steps right up to the line of fraudulent product claims wrt solar charging.
