RE: SOtM sMS-200 Battery Power

Posted by fredtr on May 13, 2017 at 20:45:03:
I don't have any battery powered audio equipment, but have been tempted. My experience is with electric bikes. Nano LiPo's are my favorite, but NiCad's can be a cost effective, low impedance, long-life, alternative to SLA's. They are more forgiving than NiMh which don't do well unless they are maintained within relatively narrow charge/discharge range. The industry has moved away from NiCad's due to the toxicity of cadmium so the best place to find them is NOS and discharged they have a long shelf life.

With that stated, SLA's are cheap, but most don't like to be discharged below 80% voltage level.
