  • Boosted cheap Android tablet runtime
Replaced the dead battery in my cheap android tablet that came with my RVi brake 3. Good quality battery with strong capacity. Wire gauge is thinner than I would like but was able to solder without issue.

  • Terrible quality
Wires are very fragile. Small gauge wires, money wasted
