Well I have a JB3 on the way and the spare battery has gotten here first. :P
I looked at the battery and it says it's a 3.6 volt LI-ion
Everything I have read puts the voltage at 5 volts...WTF?!?
Anyone want to take a look at the specified voltage on their JB3 battery?? I'm confused already! :P
-
Internal voltage on the lion batts is 3.6v. JB3 takes 5v external power. No different from any other device taking internal batts at one voltage and external at another.
-
What other devices?? The only that come to mind that i have experiece with are a D7/8 and an mp2. Both require 6 volts dc reguardless if the batteries are internal. (4 x 1.5 volt AAs)
-
I was thinking of the D7/D8/D100/M1/SBM-1/MP2. Add JB3 to the list.

If the battery is 3.6 volts and the external is 5 v it isn't like a D7 or mp2.....they both require the SAME external and internal voltage.

D7/D8 = 4 x 1.5 (6v) or 4 x 1.2 (4.8v) v. 6v external
D100/M1 = 2 x 1.5v (3v) or 2 x 1.2v (2.4v) v. 4.5v external
MP2 = 2 x 1.5v (3v) or 2 x 1.2v (2.4v) v. 5v+ external
Though I suppose rechargables in D7/8 are close to 6v when fully charged.

Ahhhh...thanks Brian...for some reason I was thinking the mp2 took 4 AAs not 2. :P

Voltage difference is probably due to a voltage regulator (remember drops a volt to run it). Car adapter says 5V 2.5a, and we KNOW it doesn't draw 2.5a - or maybe it DOES when it's CHARGING.
I have a similar problem with my Sony GRT-100 laptop. Internal battery is 14.8v/4000mAh. External input is 19.5V/6.5a. Can't find an external battery to run it in the field. Thinking of hacking the case and going direct to the internal battery hookup, but I got a 2 year extended warranty on it, and I think adding a DC plug and wiring mod to the case would kinda void it...
