I get what i wanted a safe and reliable bms Bonus it can Communicate to the inverter! The safety is spot on! (over and undervoltage protection) I connect 10 Pcs together with the provided rj45 cables This is the best Active BMS for your home! I made a mistake with the last bms wiring, but i could Check in the app that something is not good. After i repaired the wiring and checked the bms was Still good. The software update is good aswell! I tested with 40amp over 2hours charge and discharge and the MOS temperature was not over 28celsius

I am happy with the quick delivery and followup. I appreciate the quality of the product especially the inbuilt balancing and effective cutoff. I compared the cutoff to another famous BMS and noticed that JKBMS gives extra 3 to 4ah. This helps in more range from the same battery. Keep up the good work.
