Re: [AFMUG] Interesting battery backup development..

random thing from china: http://jycbattery.en.alibaba.com/product/60242486785-801546525/New_4U_48V_50Ah_Telecom_Backup_LiFePO4_Lithium_ion_polymer_Battery.html search alibaba for 48V lithium ion and you will find more. I am highly skeptical of the quality of the cells they're using, considering the cost difference between "cheap" 18650 cells and Panasonic or Sony.

Not bad. Is it just a battery? What's available on the two ethernet ports and USB port? bp <part15sbs{at}gmail{dot}com> On 10/7/2015 4:59 PM, Peter Kranz wrote: Check this out.. 48V 160Ah Lithium battery module.. I�m thinking this could be a very interesting alternative to our current telcom battery based backup solution. I think I can double my run-time in a smaller form factor.
