5 NiMH batteries and a 4.8V charger - Will it work?
Hello guys.
I have a 6V battery pack (5x1.2 NiMH ) and a 4.8 V charger which can also output a 9.6 voltage.
Can I use it to charge my 5 cell pack?
Is it bad to charge it in lower voltage than it should be?
Appreciate your replies!

Charging a 6 cell pack will not work properly if you use a charger that is meant for a 4 cell 4.8v pack. The charger for a 4 cell pack charges the pack at about 5.6volts to give each cell its maximum capacity. This is about 1.35-1.4 volts per cell. You could leave it charging for days/weeks and it simply will not reach full capacity because the charging voltage is not high enough to bring each cell to maximum capacity. For the same reason a 9.6v charger will charge at about 11.1volts to bring each cell to its maximum capacity.
This is the reason companies make a designated charger for all the possible cell counts. I would suggest purchasing a 5 cell charger to ensure a maximum charge and long life span of your batteries.

You are right.
But, guess...
I measured the output voltage of the charger, at the JR connector and it was 11.36 V, way off the 5.6V (+-20%) voltage specification for this charger. There was no load on the charger...
So there is a big issue here.
Is this bad for my pack (6V)?

I have a futaba charger with a dual charging lead, that charges a 9.6volt transmitter battery and 4.8volt receiver battery. The output voltage for the 9.6v lead will be around the 11.36volts. The charging lead for the 4.8volt battery will be around 5.6 volts. I'm not sure if there is a switch on your charger or it has dual separate leads.
But clearly 11 volts is too much for a 6volt battery and 5.6volts is not enough. With this said I would never recommend that you should try it with your 6volt battery

It so peculiar.
Instead of 5.6V the output is 11.34!
Wow...
Now what?
I wont charge my cell pack with this?

It really doesn't make sense to me. It should be half that amount to charge a 4.8v battery.
Are you sure this is for the 4.8v battery because it would make perfectly sense for a 9.6v battery. Is there a switch, or dual charging leads?

Obviously, it is a terrible mistake from the guy that assembles the charger at factory.
I don't know what they did. The point is that you can damage your electronic equipment this way.
Or even worst, to blow up a battery pack.
I bought it from a german eshop.
To answer you straight dear ryan, the charger has 3 kind of outputs:
1 for a glow plug heater
1 for battery packs with JR connector (5.6V)
1 for transmitter (with the rounded jack) at 11.4V
The JR outputs also 11.4 V. F***ing yes!

Wow, I would not trust it then. They say 5.6v +/- 20% It should not be above 6.72v according to the manufactures specs.
