Hi all, I want to build a starter battery for my car. I took some reference on internet and find this LiFeP04 battery on Walmart
https://www.walmart.com/ip/Deep-Cyc...ergency-Start-1200CCA-Group-Size-31/458039754
which has a function called "Emergency Start". I believe it is for an one-off start should the battery is over discharged and shut off by the BMS. I would like to have your advice on how the circuit is designed for this function so I can add it to my DIY battery, thanks very much!
