Question:
I have an AC300 and three (3) B300 batteries…I just purchased a 4th, a new B300k battery and hooked it up…no problem… So now i have 4 batteries operating.
I want to discharge all of the batteries to zero (0), have it shut off as required, AND then recharge as specified by the AC300/B300 manual for 2 reasons; to sync all of the batteries, and to discharge every 6 months as required by the manual…
However…The B300k manual states do not discharge below 1%, AND, then it says if you discharge below 1% (meaning off) immediately recharge (grid).
So the question is, what is the proper discharge method for the B300k?
Thank you.
Update: I ran all four batteries down to zero and everything shut off as required… when I plugged the AC300 into the grid the three B300 batteries all automatically turned on, the B300k did not, and had to be manually turned on… the manual says on page 10 it will automatically turn on … is this because it was at zero or something else?
So, no word from Bluetti support…interesting. At least acknowledge the posting.
Anyone else get a, “no response” from support. They used to be all over this forum; I guess success has superseded support.
Hello @LukeWarm ! I am suspecting that an update to your AC300 and/or B300k is what is needed to activate full communications. Perhaps @BLUETTI_CARE can help see if there are any updates needed?
I thought the B300k battery could not be mixed with B300 batteries. I have a similar setup, (AC300 and two B300 batteries) and read somewhere that the two could not be mixed. Maybe that is part of the problem?
B300 and B300k can be mixed as well as b300k and B300s.
They are supposed to respond on here…app says all up to date.
Hi @LukeWarm, Thank you for your attention to this issue.
The AC300 is an earlier model that was launched alongside the B300, so the two have excellent compatibility. The B300K, on the other hand, is a newer model released later—it’s designed to work with a wide range of host devices, which means it can’t easily identify the specific model of the host it’s connected to. For smoother recognition, we recommend turning on the AC300 first and then powering on the B300K—this helps the B300K detect the host quickly.
Another key point: during recalibration, unlike the B300, we advise not draining the B300K’s battery fully. Keeping the remaining power above 1% is sufficient.
Thank you to @hnymann for your attention and helpful reminder.
