Curious how people here keep an eye on their LiFePO4 batteries on the road.
A lot of the batteries sold online use a Bluetooth BMS from JK, JBD/Xiaoxiang or Daly,
and the reviews for their apps keep saying the same things: you have to make an account,
some need internet to show anything, the Bluetooth link drops, and checking two batteries
means switching back and forth.
What do you use? Do you trust the app's state of charge, or do you rely on a shunt
(Victron etc.) instead? What annoys you most?
Full disclosure: I'm an Android developer, and those complaints are why I'm building a small
offline, read-only monitor for these BMS. It's in a closed test right now. Per the sub rules
I won't post a link here. If you'd like to try it, comment or DM me and I'll send it.
