I have 2 St. 4 Ah battery and the 1.5 Ah just bought because it makes the device a little more manageable, which can be quite handy,
if you have to work, for example, much overhead.
That was the only reason I bought it.
However, one should note that the 4 Ah weighs about 750 g. And 1.5 Ah no, it is hoped
half, but 453 g. If you want, for example, a handy screwdriver, already notice the difference.
Otherwise, the 1.5 Ah battery, although the quality was good, but it does not come about so far. 1.5 Ah are very little.
Although he is already after 1 h full again, but the frequent charging is ultimately on the lifetime.
Whoever buys this battery should only do that if he needs the lightest possible equipment / wants.
