Use an older Tekin BC-210 on Pro-flex for charging " have to convert to be able to use on 4 cell " and use any BC-112 on PF-2 for repeaking .

May sound elaborate ,,, but both these units can be found on E-bay for pennies compared to new.

I've bought several BC-210's that retailed for $150 + for under $20.00

The BC-210 is a great unit for any Nicad pack as it pulses in the positive dirrection and then occasionally throws a neg flex to burb the cell ,,, very cool charge temps , even at high rates.

Put a 1 ohm resistor across each cell for a few days or for sealed packs use the old 10-30 ohm resistor across the entire pack for a week.

I wish they would market a 4 cell version of the pirranah 1900 pack as it is SKOR legal and a much better battery !

We bought 200 cells for our club and built our own.

I've experimented with many a linier chargers and nothings compared to the performance you get with the BC-210 ,,, after 50 cycles , the pack is as strong as ever and discharges at 2000 mah plus.

How has anyone else seen positive results with these cells ???
