ARRL. ORG  GOAL ZERO YETI 400 LITHIUM PORTABLE POWER STATION  EVEN WHEN
OPERATING FROM HOME, I USE 12 V BATTERIES EXTENSIVELY TO POWER MY STATION
EQUIPMENT BECAUSE I FIRMLY BELIEVE IN GETTING TO KNOW MY PORTABLE POWER
SETUP PRIOR TO A COMMERCIAL POWER OUTAGE IN A STORM OR OTHER INCIDENT.  I
USE CONVENTIONAL SEALED LEAD ACID SLA BATTERIES, ALONG WITH ANDERSON
POWERPOLE CONNECTORS AND SIMPLE Q PWR MICRO METER VOLTAGE/CURRENT METERS
FROM QUICKSILVER RADIO INLINE BETWEEN MY BATTERIES AND RADIOS.  CONNECTING
EVERYTHING TAKES SOME EFFORT, AND I NEED TO MAKE SOME BASIC CALCULATIONS TO
ASSESS A BATTERYS CHARGE STATUS AND HEALTH.  ANOTHER OPTION IS A GOAL ZERO
POWER STATION, WHICH IS SELF CONTAINED AND ABLE TO POWER A VARIETY OF AC
AND DC OPERATED DEVICES.  THE GOAL ZERO WEBSITE LISTS MANY RELATED PRODUCTS
THAT COULD BE USEFUL FOR AMATEURS INVOLVED WITH DISASTER OR PUBLIC SERVICE
COMMUNICATION IN AREAS WHERE COMMERCIAL AC POWER IS NOT AVAILABLE.
OVERVIEW  THE GOAL ZERO YETI 400 LITHIUM PORTABLE POWER STATION USES A LI
ION NMC LITHIUM ION NICKEL MANGANESE COBALT BATTERY WITH A RATED PACK
CAPACITY OF 428 WATT HOURS WH 10R8 V DC, 39R6 AMP HOURS AH.  THE BATTERY IS
SPECIFIED FOR HUNDREDS OF DISCHARGE/RECHARGE CYCLES, WITH A SHELF LIFE THAT
INDICATES CHARGING THE BATTERY AT LEAST ONCE EVERY 3 TO 6 MONTHS.  IDEALLY,
