Quantum battery is very good, many professional swear by it and using it in America, but in Singapore, many users facing some kind of battery cells problem, the local agent will service the battery pack for you, but many of the users find that the replacement battery cells does not perform well as compare the brand new set. I do not know why but perhaps many of us are heavy users.kensh09 said:Is the Quantum batt that unreliable? How come u need to change twice?

I DIY a homemade 6V SLA battery pack for backup my Quantum 1+, but find out that it out perform the Quantum 1+, (4.5 mah compare to 2.5mah), so I made a switch. Btw I didnt use the Quantum 2 and the Quantum turbo, so I cant tell you my comments about these two models.
Quantum Module has a lever for you to secure the dummy battery inside the battery compartment, so when I using it with SB28, and SB80DX, I just leave the battery compartment door open, they do give you a Velcro strip to secure it, but I find it unnecessary, after doing it this way for few years, nothing broken. :sweat: For SB800, I just need to remove the battery compartment door completely.bowwow said:thanks for sharing the info, catchlights.
very interesting!!
the only thing i don't like about the 1+ is the way the cable sticks out of the battery comparment and the door not closing fully for the 550EX. was wondering how difficult it would be to get the connector to fit into canon's dedicated port at the base of the 550EX. then that would be sweet!!

Clown said:problem i found with DIY lead acid and lithium battery packs is that their peak current output is not sufficiently high to give good performance. i once tried to DIY a SLA battery pack for my camera but the current draw was too low to even start the cam properly. quantums, on the other hand, has circuitry to pump out that kinda current. i'm those 'use whatever that works' kinda person but sometimes DIY stuffs just dun make the cut.
well i think max current output depends on battery types rather than sizes, cuz alkalines and NiMH seem to be able to provide a higher current dump when compared to SLA and Li rechargable packs. if u could find a combination other than a quantum pack that can power a S2pro by itself pls let me know.. haha. think i almost given up liao.enghong17 said:HI Clown,
Think the batteries comes in Voltages and Amps, like the 6V batteries, they have different amp ratings as different appliance have different loads. Usually the bigger batteries have a larger Max amp rating.
