Ron, my long experience with NiCad and now even NiMH is that they are
worthless for long-term reliability. Anybody else? There are small AGM
(RG) batteries for motorcycle applications should be a lot cheaper than
2 packs of NiMH. There's no issue paralleling them with a larger RG,
and one battery mfr says in its literature that parallel batteries of
different types runs the risk of explosion if heavy current is extracted
---From the pair. In any event, the results are unpredictable and dependent
upon the condition of either. NiMH is inferior to even NiCad for what
you are considering, and both are inferior to AGM "starting" battery
which will have less internal resistance in comparable capacity. Just a
suggestion!
