2018 F3T totally dead - any thoughts or advice?

Again, many times a LiFePO4 (aka LFP) battery, which is what that is, is shipped in sleep mode. The assumption is that the customer will put it on a charge using a proper LFP battery charger. The battery charger sends the necessary wake up voltage pulse which tells the BMS to bring the battery back on line. If you do not have the proper LFP type charger, then that’s most likely the only problem. So, it would paint a more complete picture, both to the forum and Lamonster Garage, to confirm if you and the stores were using the correct type of charger to try to wake up this battery. If you were, then the battery could truly be faulty. Otherwise, it’s a matter of not understanding how your new battery technology works.

AND, don't use a charger that is not designated as a lithium battery charger!

Yeah, charged the battery as soon as I got it.

Did you use a Lithium battery charger?
