KX3 2135 is alive and well, and hungry for energy. I'm feeding it with
AA Alkaline batteries now, but am looking for a more permanent set of
internal batteries. I have a KXBC3 installed.
I'm considering low discharge1.2v 2500 mAH NiMH AAs because they may be
recharged by the KXBC3. Regular 2700 mAH NiMH AAs can lose as much as
20% of their charge in the first 24 hours. That drops their available
power to about 2150 on the second day. Low discharge seems a better path.
Also considering NiZn batteries. Newer stabilized NiZN seem like a
useful alternative. Discharge curves seem similar to NiCd or NiMH, but
they offer 1.65 nominal voltage. I'm thinking the KXBC3 will not be a
suitable charger.
I'm thinking that the 13v of the NiZN AA batteries will allow 10W output
from the KX3, where the 9.6v of the NiMH only allows 5W output.
I also have 11.1 LiPo batteries I can use as external sources, but will
likely consider a 4S1P 14.8v 25C LiPo as a potential external battery.
Anyone go through this exercise already? I'm interested in comments.
Thanks.
