      Hi, as I dont sail as often as i should just wondering about a few points on storage of nimh batts.

      1/ stored fully charged after use or in a discharged state?

      2/ remove drive and receiver batteries (or unplug) from units?

      3/ do nimh cause black wire syndrome as cadmium batts?

      4/ my new receiver batteries only give the slow charge time, 15hrs @130mah, is it safe to fast charge them? batteries rated at 1.3 amph

      5/ similar thing, 2000mah 7.2v set, is a 1amp fast charge too much?

      any help appreciated please, my electrickery knowledge is zilch

          1. Opinions vary from one extreme to the other. I store mine at anything between 1.2v and 1v. Don't go below 1v.

          2. Unplug.

          3. No experience of this. Assume they might so unplug etc.

          4. No. Why would you need to fast-charge Rx batteries anyway?

          5. Fast-charge rate should be indicated on the label. If not then don't exceed 200 ma. Sub-C cells will generally fast-charge happily at the C rate – in this case that's 2A.
