Luka,
I disagree, Wh is a more useful measure than Ah because it gives you the capacity. For example 48Ah tells me nothing unless I have the voltage whereas with 48Wh I can calculate that at 12V it would give me 4Ah. You can always get a voltage converter if you require a different output voltage.

The 48Ah is a pointless number unless we know the voltage that was measured at. If the voltage was 3.2V (standard for a LiFePo4 cell) then the smaller one almost has 2.5x the capacity of the larger one.
Gotta love the Chinese labeling  |
