The accu is a battery pack. Size and weight match with a maximum load of 9x3=27 18650 batteries. This means a total of 150 Ah is 150/27 = 5.555 mAh each battery at 4V, but 150/3 = 50 Ah for the battery pack at 12V. Neutral information says that 5.555 mAh is not a feasible maximum for a 18650 battery, but maximum 3.500 mAh. This means 27x3.500 = 94.500 mAh for the total of batteries, and 94.500/3 = 31,5 Ah for the pack at 12V. So: with fancy 18650 batteries the total accu at 12V is not 150 but 50 Ah, and with realistic 18650 batteries about only 30 Ah. But: for the size and weight of it at a real 30Ah it is not bad, it is a handy pack. I have used it with a 12V to 19V adapter for connection to laptop, and after 5 hours without trouble the display still shows maximum green at 12V, so I think it is a reliable nice accu.

Good battery with cables and charger. Works fine and price was adequate. I have doubts about capacity, probably less than declared, but haven't yet put it into a battery ter to measure this. Quickly shipped and delivered.
