Yeah it will constantly trip your breaker. Check if you have any outlets on the breaker you have your kitchen appliances on as appliances tend to run off higher amperage breakers.
?? You over thinkâd it, just check continuity between 2 pins and see if theyâre shorted or not. They should stay open until the BMS closes them to balance, if shorted they will continue to drain power until that P group is deadâŚ
I just called BCH to ask if there would be more lots of brand new cells in the future, he said âthey come and goâ So it is possible but no guarantee that there will be more.
Apparently the free shipping is a âfuck upâ and it is supposed to have a shipping charge for the lots over 20. Confusing but whatever.
He is also sending me some pictures of what they have.
They have some Segway batteries also those might be good power and energy density.

Does anyone have a good (reliable and fast shipping) source for insulator rings in the 21700 size? Iâve been using IMR but would prefer fishpaper over plastic insulator in the future.

Wait isnât the difference between common and separate basically discharge/bypass or charge and discharge/bypass?

Sparking usually indicates you made poor contact. A proper weld shouldnât spark. Make sure to press firmly

Recommendations for a 12s smart BMS? Anything cheaper than a DieBieMS because that stuff is EXPENSIVE, and iOS compatible

This bad boy will do you right. The balance current is nothing to shake a stick at, and its not exactly compact, but other than that I have no complaints. Its very simple to use once you figure everything out, and it does its job. If you order from this website, I advise paying for expedited shipping if you want to get in within a month.

iOS supported? And they include the Bluetooth dongle with it?

Just means theres 3 wires vs 2 coming from the BMS. Thereâs B-,P-,C- for solit, or commonport has the C- and B- combined. I usually use common when bypassing discharge so I donât have to have the 3rd wire clipped hanging off.

I have one of those the bluetooth module is included.
They donât make the ios app it is third party. It is free for basic use but to program you have to pay a fee.
