Top 5 Positive Customer Reviews for 12 v li
everything is ok, battery arrived in 3 weeks to poland. it worked normally for about 2 hours, charged it to 90% and I tried to mount it to my portable speaker. but strange things happened, battery stopped working. it gave only 7 volts instead of 12 and didn't charge anymore. i opened it, checked voltage with multimeter on protection board. voltage was 12v on b-, b+, b1, b2 on pcb, but on in/out only 7v, don't know why. anyway I replaced that protection board with another one and it started working and charging again. battery is perfect for building portable speaker, this one works with tda7492p and step up converter set to 20.5v.
