You can use this as a low cost alternative to charging your battieres.  Ideally you should use a peak automatic charger for your NiMH and NiCad batteries/battery packs.  We recommend the AstroFlight charger, it is a very good charger and will ensure your batteries are properly charged and last for many many charges.  The higher the mA, the faster the battery will charge.  If you use too low of a voltage transformer, the battery won't fully charge.  If you use too high of a voltage transformer, the battery or transformer will be damaged.  The table below is a chart that can be used to safely and effectively select the right transformer to charge your batteries.
