BSLBATT Lithium is China’s Lithium battery manufacturer to offer lithium batteries for the solar street light market. We manufacture the best type of lithium cells, known as Lithium Iron Phosphate (LFP or LiFePO4), the ideal solution for renewable energy storage. There are many advantages to LiFePO4 cells. These LFP batteries are also much safer compared to sealed lead-acid batteries due to the battery management system installed. Lithium batteries offer a much better lifetime cost per kWh cycle due to their excellent cycle life, even when fully discharged to a 100% DOD. Read more below to learn why a lithium battery for solar street lights is a great choice! 

Why do we recommend lithium batteries?

To start with, I will summarize the most important benefits of lithium batteries compared to lead batteries. Lead batteries in this context refer to all the different chemistries of lead batteries and even the most modern types of lead batteries, like VRLA, deep cycle sealed (VRLA) AGM batteries, or deep cycle sealed (VRLA) gel batteries. In addition, this article will give a detailed explanation of what the differences between lithium and lead batteries mean for the performance and durability of a solar light pole.

Lead Lithium
High-temperature tolerance 20oC 40oC
Low-temperature tolerance >0oC >0oC
Turnaround cycle efficiency 75% 98%
Charge rate 0.2C 5C
DOD tolerance 50% 95%
Discharge cycles @ 80% DOD 400-500 2000
Discharge cycles @ 30% DOD 1500 7000
Weight (vs Lead) 100% ±25%
Replacement timeframe 1.5-3 years 8-10 years
Complexity Easy Complicated
Environmental impact Higher Lower
Total cost of ownership Higher Lower


Lithium iron phosphate batteries are a great choice for solar street light systems. They have the best deep discharge capabilities amongst all other battery technologies. In fact, you can discharge them up to a 100% depth of discharge (DoD) while still maintaining more than 98% efficiency. BSLBATT lithium deep cycle batteries offer a high cycle life of over 3,500 cycles at 80% DoD and over 2,500 cycles at 100% DOD. Lithium batteries for solar are particularly great as they do not require maintenance, so you can install them anywhere, even in remote areas, hassle-free and worry-free.

So, why we choose lithium batteries instead of Lead-acid?


The same lead-acid battery is heavy in weight, larger in volume, and small in energy density. The lithium battery is small in size, light in weight, and easy to transport. Compared with the lithium-ion energy storage system and lead-acid gel battery used in solar street lights, the weight and capacity are about one-third of lithium batteries. As a result, transportation is easier and its costs also reduced.

Lithium battery has higher energy density and longer service life. The lithium battery cycle life of more than 2500 times, the lead-acid battery cycle life of 800 times; the energy density of lithium battery is around 150Wh/kg, lead-acid battery is about 40Wh/kg; the charging time of the lithium battery can be full within 4 hours, and the lead-acid battery is generally full around 6 hours;

Solar street lights using lithium batteries are easy to install. When installing traditional solar street lights, a battery pit needs to be reserved, and the battery is placed in the ground box to seal it or install the lithium battery on the bracket, using a hanging type or a built-in type.

Then, it is easy to maintain and replace. The lithium-ion solar street lights only need to remove the battery from the pole or battery panel during maintenance, while traditional solar street lights need to dig out buried batteries, which is more troublesome than lithium-ion solar street lights.


Lithium battery charge and discharge electrical energy efficiency is better, lithium-ion battery charge and discharge energy conversion efficiency can be greater than 97%, and lead-acid battery charge and discharge energy conversion efficiency is about 80%, the same lithium battery than lead-acid battery volume Small, the volume of a lithium-ion battery is about 2/3 of the volume of a lead-acid battery;

The systems using AGM batteries require replacement once a year to ensure reliability. Generally, the labor cost of replacing AGM batteries exceeds the cost of the product itself, especially in Australia, Europe, North America, and other places. The risks and hazards of frequent battery replacement cannot be ignored.

BSLBATT lithium solar street light batteries are designed with a built-in battery management system (BMS). Battery management systems are designed to protect lithium batteries by intelligently responding to fluctuating conditions, including voltage, current, and temperature. The BMS also has many other alarm functions. In other words, the BMS ensures your lithium batteries are operating within the desired parameters to assure they live for many years. Lithium batteries are much more costly compared to the traditional flooded batteries and even sealed lead-acid batteries. For this reason, the BMS is a great built-in feature that helps protect and provide an excellent return for your battery investment. The BMS responds by shutting the battery down if it detects something wrong.


When you use BSLBATT lithium iron phosphate batteries (LiFePO4) for solar street lights, rest assured that you are making the right decision. This is because Canbat lithium batteries are the most reliable energy storage solution on the market today. They are designed to deliver efficient and ultra-long life power you can count on, even in less favorable conditions. BSLBATT is the lithium battery China manufacturer!
