RC Aircraft Battery Help?

Get two new battery packs, a good quality charger, AND a battery cycler. The problem with most rechargables is 'partial charge memory'. NiCad or NiMH battery packs usually never really get totally discharged after a series of flying and begin to develop a short charge or partial charge memory. Useful output diminishes over time and the packs require CYCLING. Cycling is a regimen of totally discharging and recharging 3X. DO NOT TOTALLY DISCARGE LiPo packs, you'll kill them. Only do this to NiCad and NiMH. You can make a cheap discharger from a few 6vdc or 12vdc automotive turnsignal bulbs soldered to gether in parallel with a pack connector. Just plug it in and the bulbs will draw down all the power in your packs before recharging fully with your new peak charger. Hobbico has a nice little unit called a Field Charger. Good Luck! Nosedive
