visualize the balancing from the led for the first time is pretty amazing,
You can see the chip selectively jump balance from different cell group to prevent overheating in certain area, and maximum of 6 cells are being balanced simultaneously, even in the worst case scenario where 15 cells waiting for one slow cell, the chip knows to jump between each 6 group.
The bms is blinking like “stop watching bitch just lemme do my thing”
So if you notice 1 led is not turning on for a long time, that cell is lagging behind.
If 1 led keeps turning on, that cell probably has low capacity or lost p count, you might check from there, or hell, buy a proper spot welder so you dont worry about half-ass welding no more.
Probably 100-200 units, gonna stock like 2000 empty PCBs so we can make it flexibly to demand consider the IC price are fluctuating pretty hard lately.
Will it be able to turn off the balancing and just charge balance only and just monitor each cells voltage, maby make PCB smaller pit ics on other side as well?
Nice!
The other side of the circuit board has components? Is it relatively flat or do any components really stick up over the others?
I’m wondering if the board can be mounted up against cells, especially more delicate pouch cells, or whether we will need something between the board and the cells.
they are relatively flat in the back, we decide to make a aluminum shield for this pcb, so it can be placed with the cells or pouches without having to worry about stuff sticking out and short stuff
@x-bms this is a very important note!
vibrations in super key to look at, that and water is what kills sooo much of our stuff.
I normally glue the balancing wires at the base to its connector and I lightly glue in the connector as well
I nearly always change out the balancing wires to high quality silicone wires. and that is both time-consuming and a pain to do.
So dont cheap out on the quality of the balancing wires, and keep them nice and long.
and if you in some way shape or form can make it so that we can monitor the p-groups through an app. or even better get notified when something is wrong.
