What do you use to recharge your small 4.8v battery packs? Most manufacturers claim that overcharging is safe at very low currents, below 0.1 C (where C is the current equivalent to the capacity of the battery divided by one hour). So my 4xAAA 750 mAh battery pack should use a charger that tickle charges at less than 75 mA.
The charger section of the battery pack has a DC/DC converter with a wide input range. This means that the pack can be charged from a wide variety of sources. The input voltage for charging can be as low as 5 volts and as high as 24 volts.
With an Explanded Scale Voltmeter (and typical load of 300 ma), a fully charged battery pack can show up to 5.5 volts, even with the 300ma load. The pack will lose it`s top voltage quickly, and down to 5V, the pack is still plenty strong, with something like 90-95% charge remaining. Most of the discharge for a pack occurs at 4.7 to 5V.
See attached image for my battery pack and charger. If the charger is regulated at 4.8V then it will never fully-charge that pack. NiMH cells are around 1.35 - 1.4V fully charged so the charger would have to be capable of outputting at least 5.6V @ 250mA But if it does then it will take around 3.5 hours to charge a dead 700mAh pack.

What do you use to recharge your small 4.8v battery packs?
If you are worried about discharge over time of NIMH, check out Sanyo Eneloop cells. Their rate of discharge over time is about 15% per year vs about 15% per week of standard NIMH cells. Charge your planes and even if you don''t fly for a month or 2 your batteries will be fully charged and ready to go. Andrew
4.8 Volt Battery pack
An expanded scale voltmeter should show around 5.3-5.5 volts for a fully charged 4.8 volt pack. That is under a load so a regular meter will show higher voltage. The pack is usable well below 4.8 volts but to be safe I usually recharge at 4.7 volts showing on the ESV. Some people recharge at 4.8 and above which is ok, but I found it shortens ...
Is it possible to charge Ni-CD 4.8V battery pack using IMAX B6 ...
Is this normal? What would be the end voltage on a 4.8V pack when fully charged? A 6v charge is fine. For Ni-CD batteries you need to charge the cells with a higher voltage than the nominal voltage of each cell (which is 1.2v on a Ni-CD cell). So on a 4 cell 4.8v Ni-CD battery charging with a voltage of 6v, that is 0 3v per cell above nominal ...
How Long to Does It Take to Charge a 4.8 V Battery Pack?
It takes about four hours to charge a 4.8 V battery pack. The charging time will vary depending on the type of charger you use and the condition of the battery pack. Assuming you''re referring to a 4.8-volt battery pack made up of four AA batteries, it would take around six hours to charge using a standard AA battery charger.
