Overview

Energy storage modules (ESMs)—batteries—are the heart of all DC-based, portable power systems. In an electrical circuit, the batteries act as a buffer between power generation, management, and the load. Solar Stik offers energy storage options for both 12 and 24 VDC systems. The lead-acid battery is still the most widely used 12 V energy storage device and is the standard by which all other batteries are measured. Lithium iron phosphate (LiFePO4) batteries are mostly associated with enhancing system portability, as their energy density (capacity/weight) is significantly higher than other battery chemistries.

LiFePO4 ESMs

LiFePO4 Energy Storage Modules (ESMs) can endure more charge/discharge cycles than other battery chemistries. Solar Stik uses the LiFePO4 chemistry in all its lithium-chemistry ESM products. LiFePO4 is slightly less powerful than other commercially available lithium chemistries, but it has the great advantage of using a nonflammable electrolyte, providing equivalent safety characteristics to lead-acid batteries.

Lead-acid ESMs

Lead-acid Energy Storage Modules (ESMs) are the most widely understood and used 12 V batteries. Solar Stik Lead-acid ESMs use absorbed glass mat (AGM) sealed lead-acid technology. Lead-acid ESMs are housed in rugged cases and will not leak if inverted, pierced, or otherwise compromised.
