Choosing the Right Power Supply for Your Charger. When selecting a charger, you may need to consider the power supply. Some chargers have a built-in power supply, allowing you to plug them directly into an AC wall socket. However, many LiPo chargers require an external power supply (PSU), which you may need to purchase separately.
Generally, when charging LiPo batteries, you should charge them at a 1c charge rate for best longevity. This means that you charge them at 1 amp per amp-hour of capacity.
Limited discharge current — although a NiMH battery is capable of delivering high discharge currents, repeated discharges with high load currents reduces the battery''s cycle life.

One of the prevalent battery technologies in the market today is the lithium-ion and lithium polymer. Although these two battery types share a few similar features, they are distinct in their operation mechanisms, features, and applications. In this article, let''s compare lithium ion vs lithium polymer and as we highlight their differences.
For LiFePO4 batteries, the recommended charging current is between 0.2C and 0.5C, where C is the battery''s capacity in amp-hours (Ah).
As a rule of thumb small li-ion or li-poly batteries can be charged and discharged at around 1C. "C" is a unit of measure for current equal to the cell capacity divided by one hour; so for a 200mAh battery, 1C is 200mA. Example: common 402025 150mAh battery from Adafruit: quick charge 1C, maximum continuous discharge 1C.. Slower charge and discharge eg 0.5C or

Lithium Polymer batteries, or LiPo batteries, are a newer, more advanced version of lithium-ion batteries. Like their predecessors, they have specific charging and discharging parameters that must be followed. However, LiPo batteries are more lenient than lead-acid batteries when it comes to charging rates.
Regarding charging rules, the lithium-ion and lithium-polymer batteries are not that much different. Figure 3 shows a complete charging cycle. A full charging process consists of 3 steps: PRE Charge, CC, and CV. This stage is referred to the condition that a lithium battery's initial voltage is below 2.8V.
Some consumers may have that the charge and discharge life of lithium-ion polymer batteries is “500 times.” But what is “500 times?” It refers to the number of charge and discharge cycles of the battery. Let us look at an example: Let us say there is a lithium battery that uses only half of its charge in one day and is then charged fully.
Lithium polymer batteries are the preferred choice of power source for electronic devices due to their lightweight, high energy density, and longer lifespan. However, charging them can be tricky, as they have strict charging and discharging parameters. But worry not, as we have a solution for you.
A power supply is an electronic device that delivers regulated voltage and current to an electrical load. Unlike standard chargers, power supplies are highly adjustable, making them ideal for charging batteries with specific needs like LiFePO4. Why use a power supply to charge LiFePO4 batteries?
Set the voltage: Adjust the power supply to the correct voltage for your battery pack. Set the current limit: Configure the power supply to the appropriate charging current (0.2C to 0.5C). Monitor the charging process: Use a multimeter to confirm the voltage and current.
