  • Hi, I connected two solar cells of respectively 4V and 44mA@pmpp in serie to obtain 8V in order to plug them in the sunny buddy, to charge a 850mAh 3.7V battery. But when I set Vset at 2.8V in full sun (the solar cells then deliver ~9V), I only observe a charge current of 7mA (battery is at 3.9V so not entirely charged).

    Can someone please explain me why I only have 20% of the th. pmpp current at sunny buddy output?

    Thanks
