excuse me , but i don't get the resistor thing...Or, really, any situation in which it might be needed. Just charge an extra 3x the part cost and include it, with a copied sheet that tells the customer when and how to use it. No engineering required - just a warning about what can happen if you don't use it, and instructions on how to avoid that.
Based on your support for the community here, I plan to purchase equipment from you later in the year. I live an hour away from a Home Depot, much less an electrical supply house, and must order most things online. So while I'll have wire and lugs and crimpers and such, like most people, I wouldn't have this tiny but important part just laying around. If I didn't find this in my order for a complete system because I didn't know, or forgot, that I need it, I'd be ticked. It's the little things that set a great supplier apart from the crowd. At the very least, have a checklist of likely necessary things, and have the customer go down that list prior to finalizing their order.
Every modern bms has this limiter on board now a days ( and certainly the batteries sold by CC)...
if one chooses to build a battery themselves one could expect this little part to part of their build / though process ?
