The Sunshine series of switching mode 3 stage (IUoU) chargers is designed for wet, sealed, calcium-calcium and gel batteries.

They have 3 selections of bulk (with absorption) charges and 3 float charge voltages making a total of 9 combinations of charging profiles. This is to ensure a safe, fast and complete charge as required by different types of batteries.

The also have a soft start bulk charge at about 50% of full rated current for when batteries have been depleted to less than 10.5V open circuit voltage this gives a gentle initial charge for deeply exhausted batteries.

The 20A Model LCHA20A has an auto operational fan, it also has dual outputs for charging two batteries simultaneously. In addition to the standard short circuit, over temperature, reverse polarity protections, it has an OVP (output over-voltage protection) to ensure complete protection of your battery.
