Deep Cycle Backup Battery
1、Functioning in equilibrium, high battery use, and long cycle life.
2、Encourage the extension of series-parallel applications.
This deep cycle backup battery is made from Grade A 300Ah lithium iron phosphate battery cell. Its high-density energy can provide more energy than the same size of lead-acid battery. Each 12V 300Ah deep cycle backup battery can run in a wide range of temperature environments (from -20°C to 60°C), so it can be used in various electronic equipment, no matter indoors or outdoors.
Our drop-in replacement of lead-acid battery series is expandable, they can be connected up to 8 units in parallel or series. A flexible power backup to satisfy different needs.

Front-side soldering of solar cells
This involves soldering the busbar to the front (negative) busbar of the cell. The busbar is a tinned copper strip. The soldering machine we use can spot solder the strip to the busbar at multiple points. The heat source for soldering is an infrared lamp (using the thermal effect of infrared rays). The length of the soldering strip is approximately twice the length of the cell side. The excess soldering strip is then connected to the back electrode of the cell when soldering on the back side.
Deep Cycle Backup Battery Feature
1. Functioning in equilibrium, high battery use, and long cycle life
2. It has great safety performance and can significantly lower the rate of line damage thanks to the pre-charging feature.
3. Encourage the extension of series-parallel applications
4. Long endurance, more than 50% longer endurance than lead-acid batteries of the same capacity. High rate charge and discharge
How are deep cycle and starter batteries different?
A deep cycle battery and a starter battery differ mostly in structure in lead acid batteries. Deep cycle batteries contain thicker separators, plates, and active materials that are more dense. Longer charging cycles do not cause corrosion on the thicker battery plates.
Consider a lithium battery.
Since lithium batteries may be fully charged and drained, they are all deep cycle batteries in a technical sense.

About us
What Are Some Important Deep Cycle Battery Features?
Apart from Amp Hour, discharge cycle life, and depth of discharge, here are some other features you may want to consider in a deep cycle battery.
Size and weight: Smaller batteries are easier to carry and reduce overall vehicle weight.
Voltage rating: Higher voltage batteries should be used for larger loads.
Charging time: The smaller the number, the faster the battery charges.
Durability: Batteries can be susceptible to extreme temperatures, vibrations, shocks. Pick one suited to your usage.
Shelf life: The ideal shelf life for a deep cycle battery is 15 years before it loses maximum capacity.
Take note of the battery's charging procedure. Voltage and current can frequently be adjusted with the aid of a smart charger.
Temperature tolerance: If you live in a very hot or very cold region, see if it can give power at various temperatures.
