Schumacher Battery Charger

Features:

The role of the controller is to protect the battery from overcharge and overdischarge. There is no boost function when the charging current becomes smaller on cloudy days. A common battery board is a 12V7 ampere battery matched with a battery with a 15--20W battery board. According to the conditions, you can assemble the battery panel rated voltage 18V and output 0.7--1A by series and parallel. The smallest controller is 5A which can meet your requirements. The calculation method is the same as usual battery charging, except that the charging time of the sun is relatively short. The change in charging current can be slightly larger than the 0.1C design. (7 mAh battery can't do anything, so it's more appropriate to bring an LED light)
