Hi,

I guess you're mainly concerned with it as an "enclosure", but are the PV panels in the LEDHUT and Bangood versions truly "identical"? Certainly they both appear to be Crystalline Silicon, which is superior to the cheaper Amorphous Silicon panels.

But the LEDHUT PV panel has four "sections" (about 0.5 volt per section, in series) and indeed the description states that it contains a 1.2 volt (NiMH) AA battery. This is common with low cost garden lights, which use a step-up voltage converter to drive the (3 volt) LED(s).

However, the Bangood version appears to have 8 sections (but perhaps it's just just two groups of 4 in parallel) ? Normally, 8 sections would indicate a "4 volt" panel charging a (far superior) LiFePO4 AA battery (3.2 volts). That would make it an excellent-valued product.

I'm particularly interested because the Solar Sensor that I'm developing uses (only) one AA LiFePO4 battery (not easy to obtain) to power everything (i.e. it uses only a nominal 3.3 volts supply).

EDIT: Looking very closely at the Banggod photo which shows some of the instructions, the text says that the battery should be replaced by a 1.2 volt NiMH type.

Cheers, Alan.
