please help on connectors issue

I took no offense.did not make D- because it was my best subject
the slow discharge is the part about 5 watts I/E 5 watts/12.6(full charge on 3 cell)would only be ~.4 amps.OR around 1/5C this would take 5HR+ to get rid of the energy in a 2.2 ma 3cell to about 90% used up.This is also why i say run it(even just setting there) to less than 3.7 volt
then the charger could charge at 2.2 amps to storage.Yes it would be best to have then hooked up but for storage it is not as important as when you go for a full charge.lets say the battery volts are 3.9 ,3.5 ,3.6
over all you are ok for storage
going for a full charge.you could see 3.9 4.2 4.3 the cell at 4.3 volts can be damaged from this charge cycle

as for the power supply HK has others and there are cheaper options,the one i showed is for industral systems.the one i jumped on was a great deal i don't see this as much now.

Thanks a lot airwave.
Sorry, I didn't mean any offense, and it's absolutely not your fault.
It's me who is not knowledgeable in this field :-)
I forgot everything I learnt at high school about electrcity (even though I was very very good at it).

I will try to find a power supply like you said.

just one more quetsion if I may...
When charging/discharging the batteries in storage mode, should I connect both balance and charge connectors to the relevant ports in the charger?
When I tried to discharge an almost full 2.2A battery yesterday, it was discharging so slowly that it didn't finish in more than 50 minutes...
then I noticed that I forgot to connect the balance 4 pins plug.

Since it was too late at night, I decided to cancel the activity, and discharge the batteries by flying the next day.
I did it today and managed to do my first Bixler loops ! :-D

Originally posted by Krimbu thx again guys. Kanga, I get "input vol err" with that power supply. So seems that it's not ok for the charger. airwave, what?????? what you wrote seemed Chinese at first reading :-) What I understood at second reading is that I need to have a supply of 60 Watts and this should be by getting a power supply whose A multiplied by V >= 60, right? Can you please explain the last 2 paragraphs? P.S. the supply you mentioned from HK seems to have very bad ratings from users...

Yeah reckoned it would be a bit small , but I thought it might of at least fired up , any way as Airwave said you really need something a bit bigger , have a look through some of your old appliances like old printers and stuff .

Krimbu,your charger spec's

Spec.
Input Voltage: 11~18v
Circuit power: Max Charge: 50W / Max Discharge: 5W
Charge Current Range: .1~5.0A
Discharge current range: .1~1.0A
Ni-MH/NiCd cells: 1~15
Li-ion/Poly cells: 1~6
Pb battery voltage: 2~20v
Weight: 580g
Dimensions: 133x87x33mm

the power supply needs to put out ~60watts,at 12volts this would be~5 amps at 18volts ~3 amps.
you cound try and find an old AT type pc power supply(yellow and black wires) to use it will do the job and no need for jumpes to make it work.
I use a 15volt 300 watt for several chargers at the time you could pick one up on the bay for cheap but that looks as if it is gone.
you could just use your car battery and get one latter
I would say a 15~18 volt

one that would do



the max discharge is 5 watts for you this is less than 1/2 amp at 6 cell
it is 1/4 amp. the max setting 1 amp would be at 5 volts.
a full charge 2200ma could take ~2 1/2 hours to storage charge.

the charge curent is max 50 watts so at 5 amps this is ~10 volts,you could not charge a 6 cell @ 5 amps at 6 cells it would be~ 2 amps.
for you at 3 cell you could go to ~ 4 amps(not that i would)but a 2C charge on a 2200 would be 4.4 amps
hope this helps you out some.

Thanks airwave and Kanga.
Yes, I do have the storage mode.
I'm just struggling to find a power supply to use with this charger.
When I tried using a regular 12v output power supply (from an old elec appliance) i was getting "Input Vol Err" message when trying to charge the 2.2A batteries.
So I used my car's battery :)

In addition, when I tried using storage mode this morning with this power supply (the batteries were almost fully charged), the maximum I could set the Amps on the charger were 1.0A, while the batteries are 2.2A


The specs of the power supply are:
INPUT 220-240V ~50Hz 200mA
OUTPUT 12v---800mA
Is this power supply not enough?

Thx
