• Con Kerteszradio 27/07/2017 A past selling the 4 led version. Inside of this two serial Li-po cells provided the output voltage - of course some below 9V. Now, the 3 led version contains only one cell with boost converter. Below more detailed this. The upconverter provide continuous 9V - independent the internal battery voltage. This good news-bad news situation, because the internal step-up converter superpones some noise the output voltage. The another thing : the converter has a quiescent current : is approx 60uA (0.06mA).See
• Con Ohm711 07/01/2016 Inside exactly same as sku 986563, only with different sticker... Very good and usefull battery. There are two 420mAh cells in series, so nominal voltage is 7.4V and capacity is about 400mAh (measured it with 100mA load). NOT 800mAh at 9V as description says. When fully charged voltage is about 8.3V, when fully discharged voltage is about 6V. There is battery protection, so you can't overcharge or overdischarge batteries. When is voltage about 7V there is not much energy left and battery will discharge
