My charger has an led. Green for not charging/fully charged (means its green when not plugged into the board). And red when it is charging the board. I use lipo batteries with a 10S Bestech BMS and this charger. I have left it charging for a while after my battery indicator showed 100%, but the light never turns green. I did not wanna let it charge anylonger, because I was afraid it could damage the battery. Does anyone have any ideas? Oh and the board is turned on when charging.
Its probably balancing the cells. Check the cells individually and see if they are all at 4.2, I bet you they arent.
Measure voltages from cells if theyre even and where does charger stop. And btw my bms takes forever to charge that last 0.1V
Out of balance for sure. Leave it plugged for a few hours.
depending on your indicator. My indicator shows 100% when my batteries are at 41V. So this could be a reason make sure to check with the multimeter the tension in your battery
Also check again the specs of your bms. you should see there at what tension it will stop charging the batteries
I think what your charger is doing is lighting the led green when the amps it is feeding is below a certain value and red when the amps are above that value and thus charging. So maybe your charger is detecting the idle power consumed by your board as enough to think it is still charging
I am leaving it to charge for a few hours now and see if it is just balancing. But I thought about what you sayed earlier as well. We will see
