V50
Posted by TomNew batch of this battery performed well, charged quickly and actually stopped charging once the protection circuit detected
full capacity. Previous two v50 purched in 1019 fall has quality issues, one did not charge after it was totally discharged. 2nd v50 still works. Overall the batteries performed well for low power iot remote sensing. -
Outstanding battery
Posted by Francine SparksThe battery is solid, well made and a good size for taking with me. Love the dual USB ports. I have paired it with the 9 volt solar panel, to which I added magnets. That way I can leave the Solar panel on roof of car, with battery inside car. It is so nice to come back to a fully charged battery. Feel that all Voltaic products are tops and customer service excellent as well.
