We recommend deep-cycle batteries from Trojan or other major manufacturer. You can use 6, 8,12 or 24 volt batteries as long as they are wired for 48 volts. HotSpot does not provide batteries. Please source your batteries from a reputable supplier and rely only upon the installation and use instructions provided by the battery manufacturer. - Page 20 Outdoor Electrical Connections Copyright 2013 HotSpot Energy...
- Page 21 •Use caution when using a metal tool near the batteries to prevent shorts, sparks, and possible explosions. •Keep all battery terminals clean and corrosion free. •Do not attempt to charge a frozen battery. •Always install a means of disconnect on the outside of the enclosure.
