Does anyone know if these are one time use codes? Meaning can I make two separate orders and apply discount twice?

Thanks

Haven't looked at his unit before, despite the deals that have been popping up.
Did some digging and it looks like it's a non-bluetooth JBD BMS in there. Just throwing the info out there since non-bt units tend to be a deal breaker for some.

I am going to try to swap the lead acid batteries of my 54" Ryobi zero turn mower with this. The current lead acid batteries are rated at 65ah but I think a 50ah lithium can outperform them.

I routinely see 100a+ spikes in power on my ryobi conversion, don't know if that bms will like it

That's exactly what I'm trying to do as well. But I think this BMS isn't going to cut it. The ideal option is a 100ah battery with a 200a BMS.

Thank you for pointing this out and it is a very valid point. They are advertising this battery to have 200A peak point current (they don't mention for how long though), and I was hoping that this peak point current could probably help with moments that there is a surge in draw like when blade motors get engages or cutting a thick patch of grass. What do you think?

I agree that this is not ideal, but I feel this battery is cheap enough for me to try it out and see how it goes. Worst case I will use it for solar.
