Yongnuo BatteryPack SF18 SCREEEAMS!!!
Mar 4, 2010

Dear Fellow Photographers.

I just got today my cheap E-Bay Yongnuo SF18 Battery pack (the 8 batteries version) and I love it so i just wanted to share some information and some numbers

I also have the older SF17 (the 6 batteries version), and I have an SB800 and an older SB24 where I can connect them.

SF18 $55:

SF17 $52:

I tried them with the SAME Sanyo Eneloop batteries fully charged (2000mAh)

Recharge times full power:

SB24 alone: 4 sec

SB24 + SF17: 2 sec
SB24 + SF18: 1,4 sec

SB800 alone with 4 batteries: 4,2 sec
SB800 alone with 5 batteries: 3,2 sec (big difference)

SB800 with 5 batteries + SF17: 1,8 sec
SB800 with 5 batteries + SF18: 1,3 sec (yeaaaah)

A full recharge in 1,3 sec is very nice. I know the high power battery rechargers are even faster (maybe) but it is still sweet for 55 bucks (free shipping)
As the batteries dry out it gets longer of course.

I think it is a great deal for those how use flash a lot, isn't it?

Thanks
jano
