A: The APC Power-Saving Back-UPS Pro 700 (120V) BH #APBR700G would not be good for your setup. I would recommend looking into a UPS with a larger VA rating of at least 1500VA/900W. BX1500M or CP1500AVRLCD are some good options.

Q: 2. can i plug can I plug the APC Back-UPS Pro External Battery Pack in to this backup?

A: Why don't you call the manufacturer they are more qualified to answer the question. I did have one issue with the backup and that was I had too many devices connected to it and when it performed the self test I would get an error message that indicated a space issue and power problem. I called the manufacturer and they solved my issue.

Q: 3. how warm do these units get?

A: Can't say this has ever been an issue.. The fan operates and keeps the unit cool only when it kicks in during a power failure. During normal operation I can't say I've noticed any excessive heat coming off the unit.

Q: 4. Is the fan always on? Or does it only turn on when charging the battery or when delivering power? If the fan only comes on when needed, how often does it turn on?

A: I've used many of these over the last couple of decades and I've never heard a fan come on unless the power is out and the unit is supplying the power.

Q: 9. What is the warranty on this unit? I have searched web sites and the only remark I could find was a 3 year warranty but no specification of what that includes. So basically, does the 3 year warranty also cover the battery. Also, how old are these units when you received them; I'm told if the manufacturing date of the product is more than 6 months old, you are getting cheated on the life of the battery since they only last so long?

A: This product has a 3-Year Repair or Replace Warranty.

Q: 10. Are those cards tested t o work on SONY FX6 ?

A: Technically, yes they could work however I would probably not use them in an FX6. I would either use the CFExpress Type A from Sony, or the UHS-II cards from Sandisk, Angelbird, or Prograde since they have a higher maintained write speed. https://www.bhphotovideo.com/c/product/1578709-REG/sony_80gb_cfexpress_type_a.html https://www.bhphotovideo.com/c/product/1499806-REG/prograde_digital_pgsd128gbckbh_128gb_uhs_ii_v90_sdxc.html https://www.bhphotovideo.com/c/product/1527888- https://www.bhphotovideo.com/c/product/1275619-REG/sandisk_sdsdxpk_064g_ancin_extreme_pro_uhs_ii_64gb.htmlREG/angelbird_avp128sdmk2v90_128gb_av_pro_mk2.html
