Hi
I am building a 14s battery pack with BSM bought here https://www.aliexpress.com/item/High-quality-14S-18650-lithium-battery-BMS-for-electric-bike-lithium-battery-with-20A-continuous-discharge/2030986292.html?spm=a2g0s.9042311.0.0.YcU2Cy.
After I connected all of the balance wires, the bms start to omit some burnt odor. I found out the BMS is getting very hot, all most hot to touch. Its been for a while. I guess it is doing balancing discharge/charge??
The battery i have are brand new and i have tested with multimeter on all of them, they all show 3.4v. Why would the bms trying to do so much discharge/charge? Bad bms?
Please help.
