Is this a special deal or sign of things to come?
or just order it with bluetooth if thats what you want, that's what i did it'll be here tomorrow. youtube review looked decent so i'm taking a chance on it for an off-grid project.
is a no name too cheap to be true going to be around when all the cells start to fail or radically drop capacity in a few years?
tariffs might disappear after November, depends how drunk on power the supremecourt actually is, wait and see

Are you buying more than one? Would it be possible to monitor all of them at the same time if only one was BT and the others were not if they were connected together?

In reality, lithium batteries require a constant current-constant voltage (CC-CV) charging profile, where the current is held constant until the battery reaches a certain voltage level but car battery chargers are built for constant voltage charging profile, where the voltage is held constant and the current decreases as the battery charges.
After a few seconds of thinking and some measurements when this battery arrives, my car battery chargers should work, unless one of them has extra shenanigans like recondition/de-sulfation, which shouldnt be used here.
This wouldn't charge to 100% SOC though.
If I wasn't on slickdeals, I would have coughed up the $15 or $50 or whatever proper LiFePO4 battery chargers cost.
Edit: I use Eco-Worthy's 12-24V, 5-20A charger for those wondering what charger to use.
Does it come apart without force or is cutting/sawing/filing necessary to take the case apart?
Taking it apart: Did not try to take it apart like Will Prowse on Youtube. App says scan sticker on battery but no sticker of any kind on two batteries. Manual is below useless.
I don't have much faith in these batteries so I plan to just connect them to a 2000W inverter and mount them at the bottom of a mobile tool cart so I can run corded tools/recharging cordless ones.

2. If so, what guage wiring do you run from this battery to that port and how long is that cable?
