    Cons:

    Pros:
    Very cheap compared to 'normal' batteries of the same capacity.

    Lipo battery

    posted by Subunaator on 08/09/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    Its cheap and about 3700 mAH which is pretty sweet for 22 dollahs! build quality is decent, connectors and handle currents over 20 ampers nicely have yet to find any major flaws
    Cons:
    Not quite 4000 but close enough takes long to arrive
