not duals

 

Dual-schmool.

That unit has the discharge power of 16 B6 chargers if you don't use the regenerative function. If you use the regenerative function, it has the discharge power of over 40 B6 chargers. With a suitable power supply, it can reliably charge at 13A and discharge at 10A. It can complete a cycle in just under 2 hours. If you use the regenerative function, it can discharge at 30A cutting total cycle time to 1.5 hours.

Check out the Junsi iCharger line. The Reaktor 1000W is a cheaper clone of the iCharger 3010B. They have dual units of varying capabilities, but they're going to run you $300-350.

EDIT: iCharger 4010DUO is probably the best bang for the buck. Unclear if it's internal power is 200W per channel or 100W per channel for 200W total. Either way, it's the most powerful charger I've seen.

EDIT2: reading-fail. 130W/channel; 200W total, so it would effectively be 100W if running dual. That would still allow for a 13A discharge.

I know that charger well.

No. They ruined that charger. It used to be a clone of an iCharger 206B, but it's a complete piece of garbage now. Furthermore, it only has 20W/channel of internal discharge power. To get the 300W discharge power, you MUST use the regenerative function.

To be clear, DO NOT GET THAT CHARGER. It is complete and total junk.

Again, Reaktor 1000W or the iCharger 4010DUO. Anything else is going to be a lower value. personally, I would just buy 2X of the Reaktor 1000W - still cheaper than a 4010DUO.

 

Okay, then Turnigy Reactor 30A 1000W. What dc to it?

 

I use an 85A 12V power supply converted from an enterprise server.


This is a similar 75A unit that could easily power both:

If you have a decent 12V automotive battery, you could power them with the 12V battery connected to a 10A battery charger.

If you have any spare computer power supplies laying around, you can modify them to work. You have to combine all the 12V wires into one bundle to ensure they can handle the current, and you'll need to know the rating of the 12V rail. Assume you're only going to get about 60% of the rated current.

 

It bears repeating that you should be pursuing grid charging for reconditioning. The charger exercise is only effective in identifying bad sticks.

 

How do i know which is bad cell ?

 

There are 132 cells in the pack. Identifying bad cells is too hard. You need to identify bad subpacks.

During the discharge process you check subpack voltages at 158V, 145V and 132V under load. Bad subpacks will show up as low voltages.
