Subject: [AFMUG] Li-ion Battery Backup

Lithium Ion batteries are getting so cheap these days it’s tempting to 
fabricate a battery bank out of them and use them for backup power. Do they 
behave well with constant voltage running through them supplied by a typical 
Mean Well AC to DC Converter, or would a special maintainer with an automatic 
transfer switch be required?
