  • Wrong connector
Model: 1S2P 16.28Wh/4.4Ah 2.54 Jst-XH
I like this solar batteries, however, the connector is too big, I had to cut off the wires and leave the old one in to connect them together, otherwise I would’ve give it 5 stars . Lamps stay on dark to dawn. I’d recommend getting them.

Correct does not hold charge, then how is one supposed to charge it with a female connector?

  • Seems like a good battery. Check your polarity before using.
Model: 1S2P 16.28Wh/4.4Ah 2.54 Jst-XH
Worked great in my battery powered fan. Battery terminal was wired backwards compared to the original but I knew this from the pictures. I just released the pins in the connector and swapped them around.
