Well,, I just replaced half of my silicone battery string with the BB batteries - the No. 2 and No. 3 "buddy" pairs being the BB's. I am having some problems.
Charging the half-new pack resulted in the powercheqs working awful hard. So, checking the charging with the powercheq's disconected yielded 16.2 volts for each of the BB's and about 13.9 volts for the silicones during equalization charging, and about 14.4 volts for the BB's and 13.6 for the silicones during float.
16 volts is well into the gassing range - not good for the new batteries at all.
What is happening here, that the total bulk-charging voltage (59.5 to 60 volts) is disproportionately going to the BB bateries?
I'm still looking into the problem, but for now, the BB don't seem to be bulk-charging compatable with the silicones. But, I think by buddy-pairing the BB with a still-good silicone battery, and using the powercheqs, the condition will be tolerable.
Any ideas? Thanks!
