Because of unusual #overheat, I took apart #powerbank #1 of my #lumsing #granda1plus series. First time opening it, ended up destroying the plastic on the body. Whoops. Eitherway overheat means the battery is going #bad. It is 2 years and 5 months of use. Oddly enough #2 is still fine. Wonder if i had overcharged it? Checked the individual batteries for bulge. So far none One thing is for sure am not going to use it. https://www.instagram.com/p/BmBnV3zhQbQ/?utm_source=ig_tumblr_share&igshid=13d7cwpg7ly69
