If you have an aircraft with very large servos that pull a lot of amps or more than 8 standard servos we recommend using NiCad batteries for the best results.Ĭhoosing the correct battery for your application is critical. We highly recommend NiMH batteries in applications that call for long duration but not a high amp load. When handled correctly though, NiMH batteries can be very beneficial, providing much longer run times than comparably sized and weighted NiCad batteries. This means that a charge current of 2000mA (or 2A) for a 2000mAh battery, most chargers will charge with a lower current, but there is also some chargers that uses higher current. My 'fast-charging' rates for a 4-cell 2200mah AA size NiMH is around 0.7 amps. NiCads are much more resilient to overcharging and using higher charge rates than NiMH. Transmitter packs get hot pretty quickly. Therefore, you must charge your NiMH batteries the night before each use. AA/AAA NiMH batteries are usual rated for charging up to 1C, i.e. The more cells in the pack, the lower the charge rate should be. For example, when your radio is off, a 1650mah NiMH battery can discharge itself nearly twice as quickly as a NiCad battery, typically within one week. NiMH batteries also have approximately twice the self-discharge rate of NiCad batteries when in an used state. Also, NiMH batteries will not perform well in high rate discharge applications, typically providing only a small fraction of the rated capacity in these instances. Such chargers are NOT recommended for NiMH batteries (unless otherwise specified in the charger or battery literature) as they can cause permanent damage to the NiMH cells.
Many modelers use high rate, peak detection or time-based chargers to charge NiCad batteries. In general, NiMH batteries cannot handle the high rate of charges or discharges (typically over 1.5-2 amps) that NiCad batteries can. Both types must be handled differently from one another in regards to charging and discharging procedures and philosophies. NiCad (Nickel-Cadmium) and NiMH (Nickel-Metal Hydride) are two very different types of batteries.
