I need a rechargeable battery for an electronics project but I'm unsure whether to go with Li-ion or Li-Po. I've heard they have differences in durability, power delivery, and safety, but I’m not sure which one would be the better choice. Could someone clarify their advantages and ideal use cases?

I’ve found that choosing between Li-ion and Li-Po mostly comes down to what your project needs in terms of shape, size, and power demands.
Li-ion packs are usually in sturdy metal casings (often those common 18650 cells) and have a pretty good balance of energy density and safety. They’re also cheaper and easier to find, which makes them great for most everyday electronics projects—like if you just want to power an Arduino or some sensors and aren’t too fussy about space. In general, Li-ion is a nice, reliable option if you’re not pushing high current or cramming everything into a super tight space.
Li-Po batteries, on the other hand, come in those thin, soft pouches and can be shaped in all sorts of ways, which is awesome if you’re building something with unusual dimensions or you need to save every millimeter of space. They can also handle higher discharge rates, so they’re popular in drones, RC vehicles, or anything else that needs a big burst of power in a short time. The trade-off is that they’re a bit more sensitive to overcharging, over-discharging, and physical damage—so you do have to be extra careful with how you store and charge them.
Personally, I’d go with Li-ion if cost and simplicity are your main concerns and you don’t need a crazy high current. But if your project needs a slim profile or higher power draw (like a racing drone or some intense robotics project), then Li-Po might be your best bet—just make sure you keep an eye on those charging and handling protocols!

@ankunegi Thanks for the breakdown, That really clears up the main differences. I’m leaning toward Li-ion since my project doesn’t need super high discharge rates, and I’d rather have something more stable and long-lasting.
That said, I am curious—have any of you used Li-Po in a general electronics project (not RC, drones, or high-power stuff)? Is it worth considering for something like a portable IoT device, or would Li-ion still be the better choice?

For a portable IoT device, Li-ion is generally the better choice because of its higher energy density and longer lifespan. It’ll give you more runtime per charge and is easier to manage in terms of charging circuits and protection.
That said, Li-Po can work for IoT devices, but it’s usually overkill unless you have specific design constraints—like needing a really thin form factor or a custom shape that standard Li-ion cells don’t fit. One area where Li-Po might make sense is if your device has occasional power spikes, since Li-Po batteries can handle higher discharge rates.

If you need a battery with better durability, longer lifespan, and stable power delivery, go with Li-ion—ideal for general electronics and low to moderate power applications.
If your project requires high discharge rates, lightweight design, or a flexible form factor, Li-Po is the better choice—commonly used in drones, RC vehicles, and high-performance applications.
Li-ion is more stable and lasts longer, while Li-Po is more powerful but requires careful handling.
