Thanks!

Still a "cheap Chinese BMS" though. On the plus side, it is hard to screw up shoving a bunch of mosfets on circuit boards too badly. I do try to inspect all solder joints prior to use. I don't have an inverter or heat load that could run 300A continuous to test it myself, but the number of...

It's going to take over 3hr to fully recharge the battery. I seriously doubt I'd do more than two battery drains per day.

The pack is only going to be 96Ah, so recharging would be needed for that many pulls. Dragging the battery to the mains won’t be that big of a deal, but getting an extension cord that can handle that load to where it needs to be is. But most pulls won’t be 65’ or that up there in weight. And 10...

I live on a steep hill and have stuff too heavy to carry, downhill of where it should be. Even with dragging friction, most loads will likely be under 3000lbs. Full extension is 65’ with line speed ranging from 11.2 fpm to 5.8 fpm based on load (3000lbs vs 12000lbs). So worst case scenario of...

Aren't all BMSs cheap Chinese BMSs? Regardless, my use case could probably be done with a 5500lb class winch, but those pull 300A at 5000 load while the 12000lb class winch I got is around 200A at the 5000lb pull. It should be rare to max out the winch. Plus I was citing max amp draw from...

So I need to build a battery box to run a 12v winch. The winch manual puts max amp draw at 430A. I’m using headway cells from batteryhookup super beast pack converted to 12v. I’ve previously made a motorcycle battery out of these headway cells and was impressed with amp output and ease of...
