Well designed and good quality board. Paired with two small 6v 0.6W solar panels charging a single 3.7v 2600mAh lipo batt. Love that it provides all connections required: BAT, solar cell, and load. My load is light so this device seems to keep up, as configured, with 24hr current drain. Florida with lots of sun. More testing needed, but definitely encouraged. I will buy more.
I expected to purchase a complete working battery charger. Not just a portion of one. This was not mentioned that it needed other parts to be a working charger. There I no mention of what parts are needed or were to go to purchase them either. Not really happy with this purchase and still can not charge my battery.
This charger works great with a 6 volt 1 watt panel, I've bought about 10 of these and have had no problems.
The product works fine to charge batteries from solar modules. Delivery service is very fast, and the product arrived in perfect conditions. Quite happy with this purchase.
Ce chargeur fonctionne très bien avec un panneau de 6 volts et 1 watt. J'en ai acheté environ 10 et je n’ai eu aucun problème.
