Excellent! 1 thing to note there is a setting in the tools called enable below freezing discharging, for now please do not enable it, as its causing some issues on a few devices, we will have it resolved on version 4.8 that was just sent to Apple / Google for approval.
For the test the BMS will eat about 7-8 AH, our 150 eats about 4 ah, more mosfets = more loss.

Nice work 👍

Thanks!

Would this battery fit in the Licitti Battery Box you have sitting on the work top ?

[@massa-blasta]

Why would I buy this when I can buy a 300Ah LiFePO4 for less than $1000 and add a bluetooth monitor for $40? Enjoybot has been well reviewed as a budget battery. Looks like a great battery for kinda DIY rich people.

[@BradCagle]

Yeah, there's cheaper options. This is certainly a upper tier quality level product. With the SFK you're getting a smaller size, cell level monitoring & built-in shunt provided by the Blutooth BMS, self heating, and USA support from this US company. So my opinion if I'm on a really tight budget I might be looking at something like the Enjoybot, otherwise I would want something like the SFK. Thanks for the comment.

This place sucks they have bad customer service. I don't recommend them. You're better off cutting the middle man and ordering yourself from China sad to say.
