Convert your standard NiMH or NiCD Transmitter pack into a Lithium pack. Lithium batteries are perfect candidates for transmitters since they weigh less and hold much more capacity. Best of all the none usage life of a Lithium pack is extremely long. You can leave a charged pack for weeks or even months and it will be ready for usage any time ( they do not self dischargee the way NiMH or NiCD do ). Duralite packs are very nice and are available here for multiple transmitter types. Also remember to order a charger for your new Lithium Pack !!! Also available is an AC adapter so you may connect the 12V chargers for these packs directly to a 120 AC outlet !!!
