One more here with bad battery,mine just shut down , sometimes 30% ,sometimes more percentage,I just order 2 new battery’s from the link, just seems new jumpers have defective battery,hope this ones can hold charge better : (
Mine just like 1 month old, with this new battery’s how the charge works?the battery detects the mAh and stops when full ?since what I understand the jumper board only detects stock amperage
