Hydrocaps for IBE cells [RE-wrenches]

[Dana Orzel]

My .02 -  I quit selling "Hydro caps" years ago after getting in a
conversation with the manufacturer [I think from Florida?] where he was
telling me that 28.8 volts and higher [29.4VDC for unheated battery packs in
winter] voltages were outside the design of their product and of course they
would fail and melt. We were to be "charging to 26.8 to 27.2 VDC and holding
at these float voltages till the battery was full." We went round and round
and I gave up trying to convince him that we needed to get to higher
voltages. I regularly run into melted down sets have removed so many sets of
melted Hydrocaps since that conversation that I have not purchased or
specified them in years. Great idea but longevity & quality seems to be
poor.

Are there long life-high quality rewatering caps that are approved for
higher voltages these days?
Will they handle 31VDC for an equalizations? Or do they need to be removed?
[messy and a problem with auto-equalizations functions]
