Review on Rechargeable 12V 11000MAh 9V 14500MAh 5V 26400MAh DC Output Lithium-Ion Battery Pack For LED Strip, CCTV Camera, Portable Li-Ion Power Bank With AC/DC Charger - Black by Chris Doe

UPDATED:6/12/17: I bought a second one b/c I wanted to see what happened with the first one and needed a new one anyway. In my updated opinion ,this is really the best game in town when it comes to powering Arduino projects.The reason I updated to five stars from two is that I found that it was the motor controller that was short circuiting. The problem was the in-line fuse (thermal auto-reset) was not reacting fast enough to the short allowing the short to affect the power supply. The Talentcell started to overheat, which in turn caused the Talentcell to shutdown power to all power ports. So based on my non-scientific observations, the Talentcell "reacted" to the short by shutting down power.6/917When I first bought this for my project I was excited. The battery life was within realistic expectations, the battery cells top notch. Everything was running well until today. I noticed that my project had stopped working. I checked the TalentCell unit and the Capacitors -there are two of them right over the 12v input/output - were extremely hot. Also the acrid smell of smoldering electronics was strong.So I did a test. I let the unit cool off. Then I tried the 9v side. Everything works ok no overheating. Next I try plugging in the project to the 12v side. Turn battery unit off, then turn on. All four green lights come on as well as the red light. After a few seconds the capacitors start to heat up. Then the green lights start to go out one by one until just the red is remaining. This happened when I was consuming electricity only, not powering and consuming.The project is a simple weather station powered by a solar panel (25watt - 1.54A rated - 1.4A actual). The Arduino weather station side is powered by the 9v power supply to a step down regulator that can take any voltage from 7v to 15v and bring it down to 5v needed for the project. The solar panel tracking motor is powered by the 12v side. The motor uses a 5a auto-reset fuse. I put that in there to prevent stall current spikes, but in testing the motor never went over 1A. The solar panel feeds into a Li-ion Mppt charge controller and then to the 12v (using the y connector included with Talent Cell battery). The motor is a 3000rpm 12v .58A Brushed motor.I really want this to work. I would love to hear from the company to get their input on this to see if I had a faulty board or if there were too many charge cycles for this unit.The batteries are still rocking and seem unaffected.
