RE: Sirius Chargers:
Dennis
I fully agree that there are many good chargers available. There are also some not so good chargers available. Therein lies the value of RCU.
I choose a Sirius charger a few years ago. I have used it exclusively for my Tx and Rx packs (except on new packs, which I slow charge and recycle a few times before use). I check the voltage on the packs often. Initally, after a few months, I got into a panic. I was not sure what was happening with the packs. I purchased the Sirius cycler. Now I can check the packs for capacity occasionally.
The Sirius unit does not have the flexibility that some other chargers do, and I have chargers for other purposes.
Red Schoefield, of the battery forum is a friend of mine. His position is that the "burp" charging adds nothing to the Sirius unit. At the same time, he acknowldges that it does no harm. Red is a genuine expert. He co-authored a book on batteries when he was at GE that is still an industry standard. He feels that there are other chargers that are every bit as good.
We probably lose more planes to bad charging and bad linkages than to dumb thumbs. My advice to anyone is to research the charger of interest and buy the one that best suits your demands.
