It’s a pcb with mosfets on it. A rocker switch comes with them.
I’m out right now, but will have a bunch in a week or so.

Does a charge only BMS protect the battery from getting too low on power?
Your vesc’s do that.

@psychotiller The VESC monitors the whole pack and the BMS monitors each cell. So if one cell gets to low the whole battery pack is destroyed?
The bms monitors cell groups. Not individual cells, Same as the vesc.
The low voltage cutoff in your vesc monitors voltage sag, If any cell forces your pack voltage below the cutoff the vesc shuts down.
Hate to say it, but I’ve seen and read about more battery failures using charge/discharge bms’s than packs running with no bms.
I’ve also been doing alot of battery repairs lately for people with dead cells. all of those packs had charge/discharge bms’s.
Don’t lay too much trust in a bms. You need to watch your percentage display, periodically check your cell balance levels, and make sure you turn your board off when you’re not riding it.

@psychotiller Okay. Thanks for the help. I think im going to buy a charge only BMS instead (this bms) to save some money and space. But how am i going to connect the battery to the VESC? Number 1 or number 2?
Your main Positive and Negative wires (10 or 12awg) go straight to an xt90. which you will plug into your vescs.
The bms is wired to the battery. It’s only connection other than to the battery, is to the charge port.

If you want to save a couple bucks on mounting hardware go to your local hardware store and get 10-32 nuts and bolts. This is for mounting the truck.
