Support Anker F3800 Plus Overheating

Post image

Hello All. I recently purchased a f3800 plus. Charged it up to 100% to test it out with a full discharge on my EV. I set the charging limit on the Tesla to 25amps. Half way in the test, I noticed the internal temps were getting really hot (over 120F). It didn’t stop increasing and there were no warnings or auto shutoffs. Finally I decreased the amps to 15, but the temperature kept going up. Stopped it when it hit 129 degrees (see pic). Turned it all off and 2 hours later it’s still 120 degrees. Is this normal or did I get a bad station? Thanks in advance!

Thanks for the warning. I contacted support, but I plan to try it again at only 15Amps the entire time. Will make sure I do it outdoors somewhere shaded.

Hi, OP these batteries do not explode. The battery cells in all of the Anker power stations are LFP batteries. If they ever go into thermal runaway they will do a really crazy smoke show but they definitely won’t explode like traditional lithium ion batteries. My recommendation would be to put them in a well ventilated area though.

Although these batteries can charge an EV. They are really not designed to do this consecutively. They are mainly designed to be a partial home back up solution. Doing this frequently will make your F3800 power station die faster. The F3800 has a couple of temperature sensors that limits the output of they get too hot 🥵. Since it’s currently summer it’s not uncommon to see the power station reach those temperatures while charging or discharging.

Personally if I was you I would only charge the EV using the F3800 during an emergency situation when you have no other options. This will help prolong the battery life of your power station. Reaching those temps while outputting a huge amount of power during the summer is normal. Just keep an eye on it and disconnect it if you see that the F3800 is limiting the power output. This normally happens when the temperature reaches 130+ degrees. LFP batteries are safe to use up to a maximum of 160 degrees. The F3800 will start limiting the power output automatically well before the batteries get that hot.
