What did you end up doing with that bricked BMS? I could use it for parts and would be willing to pay you for it!

I am having the same problem but with an Epever XTR 4215N. I have a shunt inline which was calibrated when doing full discharge and full charge battery testing. The shunt is telling me that the batteries are 85% charged but the Epever 4215N is saying 97% charged. This morning it started out at...

Would you be willing to sell the broken Overkill 8s 24v BMS so I can expriment with it?

I was notified that if I communicate with Overkill Solar to use the following email address: support@overkillsolar.com as they phased out the old email address.

Can you describe the non-working state of your DOA BMS?

Do you have the windows version of the source? Also, do you know how I can get the firmware source for the JBD 4s 12 v 120a and 8s 24v 100a and 16s 48v 100a BMS? The reason for asking is that I am in the process of designing a 300 amp 4s 12 v and a 8s 24 v and a 16s 48v LiFePO4 (280 Ah cells)...

Welcome to the club. This is ridiculous. Looks like if the problem is too hard they just ignore you.

Mike, Yes, I did purchase with a credit card but I need the BMS. The problem is he not only marked the BMS with the wrong label but he sent me a BMS for Li Ion batteries. Lucky I hooked up the PC app and saw that or I would have blown up $1400 worth of LiFePO4 280 Ah batteries which I waited...

How do you order it with the M6 mounting terminals on AliExpress at the link in Post#34? I don't see a way.

Thank you for that. I was using the link on Post #1 but your link is more accurate.

I am having the same problem with support for an 8s 100A LiFePO4 BMS. It seems the BMS they sent to me from OKS is for Li Ion and I am asking for the .fig file for LiFePO4 but no answer. Initially I got a response from Steve with regard to an apparent mislabel of the product. My 8s 100A BMS was...

There is a good writeup on Solacity.com at this link: https://www.solacity.com/how-to-keep-lifepo4-lithium-ion-batteries-happy/ at this link there is a cheat sheet on the 12 volt charge settings for LiFePO4 batteries.

Once the battery is top balanced then there is specific care that must be done to maximize the life cycles for these LiFePO4 batteries. There is a good writeup on Solacity.com at this link: https://www.solacity.com/how-to-keep-lifepo4-lithium-ion-batteries-happy/ at this link there is a cheat...
