100AH 12V Gel Batteries
$205.00
Maintenance Free & No Leakage: This battery is comprised of gel instead of liquid, so there is no maintenance required to keep the battery working properly. Manufactured with an advanced valve regulated technology, GEL Batteries save you from acid leakage and frequent maintenance.
Extended Service Lifetime: Corrosion-resistant grids enable a design life of up to 12 years in standby applications and more than 750 charge/discharge cycles at 50% DOD in cyclic applications.
Longer Shelf Life: Made of high purity materials, GEL Batteries reduce the monthly self-discharge rate below 3% at 77℉ (25℃), which is 5 times lower than their Flooded counterparts. No need to recharge the dormant battery frequently.
Excellent Deep Discharge Recovery: Proprietary plate composition and patented gel electrolyte ensures excellent recovery capability after excessive deep discharge. This means that GEL batteries can discharge more and still be recharged like new. Unlike Flooded batteries, they are not allowed to discharge too much.
Install Them Anywhere: Maintenance free, no leakage, no toxic gas generation, vibration resistant, and stable performance at high (60°C) and low (-15.5°C) temperature make GEL Batteries able to be used in virtually any position. They can run in various systems, including marine, RV, van, off-grid, home backup power, and more!

40A Solar Charge Controller 12V / 24V Auto work; Max input voltage: 40V; Max PV power 400W /in 12V, 900W / in 24V. With Dual 5V / 2A max.
Solar Charge Controller 20 amps only suitable for lead acid batteries: OPEN, AGM, GEL and Seal, not for nickel hydride, lithium, Liions, or other batteries.
Three Load work mode (Settable), 【1-15H】and 【0H】both belong to the light control mode, and the load will turned off at dawn. 【24H】Load output 24 hours (except for battery under voltage) 【1-15H】Load on after sunset and closed after setting hours (turn off load after dawn) 【0H】Dusk to dawn (the load will turned off at dawn)
For protecting the lifespan of your battery, once the voltage of the battery drop below 9V, the solar controller will turn off automatically. Only suitable for small home solar system,
Charge controller easy to install and operate: Please always connect the battery before connect the solar panel, only suitable for small home solar system.
A combination of multiple tracking algorithms enables accurate tracking of the optimum working point on the I-V curve in an extremely short time.
Advanced digital power supply technologies raise the circuit's energy conversion efficiency to as high as 98%.
Charging program options are available for different types of batteries including gel batteries, sealed batteries, open batteries.
The controller features a limited current charging mode. When the solar panel power exceeds a certain level and the charging current is larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level.
Historical data storage function is available, and data can be stored for up to a year.
The controller is equipped with an LCD screen with which users can not only check device operating data and statuses, but also modify controller parameters.
The controller employs a built-in over-temperature protection mechanism. When temperature surpasses the set value, the charging current will decline in linear proportion to the temperature so as to curb the temperature rise of the controller, effectively keeping the controller from being damaged by overheat.
Featuring a temperature compensation function, the controller can automatically adjust charging and discharging parameters in order to extend the battery's service life.
