    Knowledge Solar Charge Controllers: MPPT vs. PWM

    A solar charge controller, also known as a solar regulator, manages the power going into and coming out of the battery of a photovoltaic system. It's fundamentally a voltage and current regulator that prevents a battery bank from overcharging. The charge controller regulates the current to the...

    Products Rechargeable Batteries for Solar Lights

    In solar lights, the energy output from solar photovoltaic systems is generally stored in a rechargeable battery or in an array of rechargeable battery cells (battery bank). During the day, solar panels convert solar energy into electrical energy using the photovoltaic effect of a p-n junction...

    Knowledge What Is a Lithium Polymer Battery

    A lithium polymer (abbreviated as LiPo) battery is a rechargeable lithium ion battery that uses a solid polymer electrolyte instead of a liquid electrolyte. It is technically a lithium-ion polymer battery. The electrochemistry of a LiPo battery is essentially the same as a Li-ion battery. Both...

    Knowledge What Is a Deep Cycle Battery

    A deep cycle battery is a rechargeable battery designed to have the majority of their capacity used before being recharged. A deep cycle refers to one complete charging and discharging of the battery. Battery designs generally assume a number of discharge-charge cycles a rechargeable battery can...

    Knowledge What Is a Solid State Battery

    A solid state battery is an electrochemical storage device that uses solid electrodes and a solid separator/electrolyte system without any liquid component. In a battery, the anode (negative electrode) and cathode (positive electrode) are separated by the electrolyte. The electrolyte transports...

    Knowledge Lithium-ion Battery

    A lithium-ion battery is a rechargeable battery which operates by intercalating and de-intercalating lithium ions into the anode and cathode depending on whether the electrochemical cell is being charged or discharged. Common battery chemistries currently in use today include lead-acid, nickel...

    Knowledge What Is a Gel Battery

    A gel battery is a sealed lead-acid (SLA) battery with a gelled electrolyte. In lead acid batteries, the electrolysis of the electrolyte during charging causes decomposition of water in the electrolyte. The gas products generated during this process are either recombined internal to the battery...

    Knowledge What Is an AGM Battery

    An AGM battery is sealed lead-acid (SLA) battery that has its electrolyte soaked in a porous absorbed glass mat (AGM) separator. The absorbed glass mat construction allows the electrolyte to be immobilized, which means the batteries of this type can be operated in any orientation without fear of...

    Knowledge What Is a VRLA Battery (Sealed Lead Acid Battery)

    A valve regulated lead acid (VRLA) battery is a sealed lead acid (SLA) battery that has the electrolyte immobilized within the cell. Batteries of this type have a safety vent (pressure relief valve) to release gas in case of excessive internal pressure buildup. The VRLA battery thus gets its...

    Knowledge Lead-acid Battery: Flooded (FLA) vs. Sealed (SLA)

    A lead-acid battery is a rechargeable energy storage device that is constructed with a lead negative electrode (anode), a lead oxide positive electrode (cathode) and a sulphuric acid electrolyte. Invented in 1859 by French physicist Gaston Plante, lead-acid batteries are the grandfather of...

    Knowledge NiMH Battery | Nickel Metal Hydride Rechargeable Battery

    An NiMH battery is a rechargeable battery that uses nickel hydroxide for the positive electrode (cathode) and a hydrogen-absorbing alloy for the negative electrode. NiMH or Ni-MH is an abbreviation for nickel-metal hydride. The NiMH battery chemistry is a hybrid of the proven cathode chemistry...

    Knowledge Rechargeable Batteries: Lead-acid vs. Lithium-ion vs. NiMH

    A battery is an electrochemical device that stores and releases electrical energy using chemical reactions. A battery is made up of one or more electrochemical cells. An electrochemical cell or battery cell consists of a positive electrode (cathode) which accepts electrons, negative electrode...
