Lithium Batteries are extremely sensitive and dangerous to use without a proper protection circuit. Here Quartz components present a BMS circuit that can be easily used and installed in an 32650 Li-ion Battery. Since this is rated for 1S battery, the operating voltage is 2.5V to 3.65V. It supports 6A of current. This is a Battery Management System circuit that monitors the charging and discharging profile of the battery. It is designed for more than 20,000 hours of operations to protect from over voltage, over current, over charge related conditions.

In the past few years, the cost of solar panels are decreasing drastically but the overall cost of the Off-Grid solar system is still significant. The cost of the traditionally used Lead-Acid battery and their limited lifespan compared to solar modules (25+ years) increases the total cost of the whole system. So, If you are planning to install new solar panels for your home or office, it is very important to select the right battery for your system. You need battery solutions that have greater capacity, a high power potential, a longer lifespan, are sustainable, safe, and fit into your needs.
Lithium-ion batteries have become a go-to option for energy storage in solar systems, but technology has advanced, a new winner in the race for energy storage solutions has emerged: lithium iron phosphate batteries (LiFePO4). There are many advantages of the LiFePo4 battery over traditional Lead-acid batteries which are described in detail in the next step.
In this Instructable, I will show you, how to make a LiFePO4 Battery Pack for applications like Off-Grid Solar System, Solar Generator, Electric Vehicle, Power wall, etc. The fundamental is very simple: Just to combined the number of LiFePo4 cells in series and parallel to make a bigger pack and finally to ensure safety by adding a BMS to it. The LiFePo4 cells come in a variety of sizes, but here I used the 32650 type.
Tools Used:1. Spot Welder2. Spot Welding Pen3. Soldering Iron4. Wire Cutter5. Wire Stripper6. Hot Air Blower7. Multimeter
Constant Power Delivery:
A major difference between LiFePO4 batteries and lead-acid batteries is that the Lithium Iron Phosphate battery capacity is independent of the discharge rate. It can constantly deliver the same amount of power throughout its discharge cycle. However, for lead-acid batteries, the rated capacity decreases with an increase in discharge rate.
Lithium batteries also have a longer cycle life than lead-acid batteries. LiFePO4 batteries can also last a very long time. Good quality batteries are rated around 3000 cycles, at a full 100% charge/discharge cycle. If you did that every day it makes for over 8 years of cycling! They last even longer when used in less-than-100% cycles, in fact for simplicity you can use a linear relationship: 50% discharge cycles mean twice the cycles, 33% discharge cycles and you can reasonably expect three times the cycles.
High / Cold Temperature Performance:
It also got superior high-temperature performance when compared to lead-acid batteries. Lithium batteries perform especially well at high temperatures than Lead-acid batteries. Lithium batteries also have a higher discharge capacity in cold temperatures as well.
LiFePo4 can be installed in any position as they don’t have any chance of leakage. Whereas for Lead Acid battery’s chances of leakage is high.
A LiFePO4 battery also weighs less than 1/2 of a lead-acid battery of similar capacity
Batteries may be used in series and or parallel to achieve higher operating voltages and or capacities to achieve the desired requirement for a specific application.
Connecting Cells in series add the voltage of the two batteries, but it keeps the same amperage rating (also known as Amp-Hours).
Example: Connecting two 3.2V / 6000mAh cells in series will produce 6.4V, but the total capacity remains the same ( 6000mAh ).
Parallel connections will increase your current rating (Amp-Hours ), but the voltage will stay the same. Ultimately you will make a single cell with a higher capacity.
