No there is no allround resistor for this purpose. You have to built up your own specific resistor for your type of battery (if it is a 3s, 4s or 6s) and for the desiered strength of discharge current.

When the blinding of halogen light bulbs is no problem for you, it would be the cheapest way to use 12V or 24V 6.35 pin based lamps for a external discharge resistor.

If you will use resistors, then the „truglodites iCharger Expanded Discharge tool--Spreadsheet“

http://www.rcgroups.com/forums/showa...1&d=1320227505

would be a good help.

When you can specify your type of battery and the aimed discharge current, I can give you some further advice.

Use these 2 points of calibration method, to ensure voltage can be well calibrated:
 Connecting nS batteries,and calibrate ”Vo” first。
(3010B,1010B(+): n=10 306B,206B,106(+):n=6 208B:n=8)
 Then connection 3S(11-13V) batteries,and calibrate ”Vo”.


You can connect 6S first, then 3S to calibrate, and repeat several times to reach the correct value, if it still fail, we are sorry your charger need repairing. I'll try your method above before I pack and send my charger back.

Thanks for the reply, I've contacted progressive customer service and they told me to send it back for RMA out of warranty repair. Hopefully they can fix the problem.

Regenerative discharge.

Btw, I thought bulbs were useless as external discharge resistor because of the aggressive change in resistance?

That is, apparently, a problem. I'm wiring up a bulb discharge thingamabob right now, but it'll only be used with the charger in the Monitor mode.

Could be a problem, when you will go to the max. limit. Then the solution is to divide the load and start up with the half load.

I built my resistor-based discharge load intending to use it with Expanded Discharge (Discharge+). But that didn't really work out for me. The current ended up being higher than the allowable range for my 106B+.

I ended up simply using Monitor mode, which worked nicely, and lets me discharge at however many amps I want (~12A on 6S, for ~300W). I just have to disconnect the load manually when the Monitor alarm goes off.

Could anyone tell me if my thinking is right on this icharger 106B+ display
0.08 = 80 milliamps
0.80 = 800 milliamps
8.00 = 8 amps
and so on and so forth, just making sure not to over charge anything.
I charge my 3.7 volt 150mah lipo battery at 0.10 which should be 100 milliamps ?
Thank You

Yes, your numbers are absolutely right.

measuring IR ?

Hi
I have a 106B and was told that my nano-tech batteries IR should be around 2 for all cells, and they all are, but when measuring IR on a quite new Life 3S Tx battery it says 44-40-30.
Does anyone know what i can expect to measure for the different type of batteries like Lipo, Nano-Tech Lipo, Life, and 18650 batteries. What values are good and what values are not good? I've tried to read about it, but i'm not very good at this electro stuff, so please bear over me with a table

I measure the batteries right after charge is finished in room temperature.

IR also depends on cell capacity.
Tx batteries usually have low C-rating so relatively high IR is normal, but the variation you got seems a bit big.

Hei Fred
I saw a list a few years ago that gave me an idea of what was an acceptable range for the different batteries, but now I can't find it.
My batts:
TGY nano-tech 3S 5000mah flight batts
TGY 3S LiFe 1500mah
No Name 3S 800mah
No Name 3S 1500mah
