[* black] Speaking of the protection board: this is a Shenzen Dalishen Technology [http://www.szdlskj.com/product/xinzheng_221.html|DDJ10A9|new_window=true].
[* icon_reminder] The board in their product photo got a much better soldering job than ours.
[* red] The four large components are MOSFETs responsible for charging and discharging, and have pretty skimpy solder joints.
[* icon_note] So far this is the only sketchiness we’ve seen, although it is a bit concerning. These particular solder joints are going to see a lot of power as the battery is charging and discharging.
