[&o]What would be the proper procedure for using the new "power taps" for checking and balancing multi cell Lipo packs?[sm=spinnyeyes.gif]Thanks

The taps should allow you to measure the voltage of each cell separately. If they are off by more than 10 mv then you can charge them separately via the same taps.

I have the same question, not what they are for, but what the procedeure is for 3C lipo with 2 taps.

What Red has suggested is correct.

Here is what I do manually until the new FMA Cell Pro devices and chargers are released for sale.

[ul][*] After charging, measure the voltage of each cell using the taps (should be 4.2v)[*] If the voltage of each cell is within 0.01v to 0.05v of the others then you are ok[*] If not, set the charger to 1s and charge across the taps where you meaured the low voltage
[/ul]

If you use a smart charger like the Apache 2500, you are fairly safe from making a mistake as the charger will flash on any invalid setup.

In summary, the taps simply allow you to measure the individual cell voltages if you connect a voltmeter across them correctly or if you connect a charger like the Apache 2500 across them correctly when set to a 1-cell charge with a reasonable current setting like 1C.

Unless you have used your Lithium pack extensively or have created a larger pack by connecting several smaller ones together, you will not likely see an unbalance.
