Silvertel Ag105 Miniature Lithium-ion Charge Controller

Silvertel Ag105 Miniature Lithium-ion Charge Controller is a solar charge controller for protected Lithium-ion (Li-ion) and Lithium Polymer (Li-Po) batteries that can also be used with a fixed DC supply in standalone applications. The module design requires very few supporting components to configure the charger to any application. With a wide 11V_DC to 36V_DC operating input range and intelligent charging techniques [such as maximum power point tracking (MPPT)], the Ag105 will adjust the charge rate to optimize power produced by a solar panel. The Ag105 Miniature Lithium-ion Charge Controller can be configured for 1, 2, or 3 series cell Li-ion batteries, with four voltage per-cell options to balance serviceable battery lifetime and usable capacity.
