Buy Lithium Solar Batteries in 2024: How To Choose A LiFePO4 Battery

When selecting solar batteries, you need to compare different lithium iron phosphate batteries based on capacity, depth of discharge (DOD), battery life, and more to find the best battery for your PV system based on your needs.

Capacity: how many amount of electricity that a solar cell can store. This data is usually measured in watt-hours (Wh) or kilowatt-hours (kWh).

Depth of Discharge(DoD): DoD is a term that describes how much of a LiFePO4 battery's capacity has been used up. It is usually expressed as a percentage of the total capacity of the battery.

For example, if a LiFePO4 battery has a capacity of 100 Ah and it has been discharged by 20 Ah, the DoD is 20%. The higher the DoD, the more energy the battery has delivered. However, the DoD also affects the lifespan and performance of the battery.

Cycle Life: How many times a lithium ion battery can be fully charged and discharged before its capacity drops below a certain level.

For example, SVC LiFePO4 Battery has 6,000 cycle life - it means that it can support 6,000 COMPLETE discharge/charge cycles before its capacity falls below 80% of its original capacity.

Continuous Charging and Discharging Rate:  How fast a battery can be charged or discharged without damaging its performance or lifespan. It is usually expressed as a C-rate, which is the ratio of the current to the capacity of the battery. For example, a 1C rate means that the charge or discharge current is equal to the capacity of the battery.

Battery Life and Warranty

how long a battery can provide power before it needs to be replaced. Battery life depends on various factors, such as the type, quality, and usage of the battery.

Battery warranty is a term that describes the guarantee that a battery manufacturer or seller provides to the customer, promising to repair or replace the battery if it fails to perform as expected within a certain period of time or under certain conditions.
