Your question suggests you are a novice at electric flying.
The function of the ESC (electronic speed controller) is to control the speed of the motor.
It is the battery (usually a LiPo) that you charge and this must be done using a dedicated LiPo charger suitable for the size of the battery you intend to use.
More details of what you intend to build would help.

The lipo battery and ESC are combined in this I'm pretty sure. I am building a RC wing based loosely on Samm Shepered's design on YouTube. I don't know what type of lipo charger I need to charge the Lipo/ESC. The videos I've seen so far say I need to plug the lipo to a charger with two connections, one for power and the other a balance plug, but you can see that mine doesn't have a balance plug and instead only an XT60 plug, so I want to know what charger I need to safely charge it.
If what you have is what's in the picture then those are only ESCs without batteries. Here's what a complete set up looks like:
Ok nvm what I said, I thought they were combined. Would you be able to recommend a battery I can use for the ESC I have? And a cheap charger to go along with it?If what you have is what's in the picture then those are only ESCs without batteries. Here's what a complete set up looks like:

The ideal battery selection for the model : 1. Fully assemble the model, ready for flight 2. Weigh the model 3. Determine the maximum thrust of your engine in its characteristics. 4. The difference between the thrust and the actual weight of the model is the maximum weight of the battery. 2S or 3S, 4S - from the characteristics of the engine for maximum thrust. If the difference is negative, the model will fly like a brick)))

Big enough for a 2S or 3s 1500 mah. When you buy the battery, get a matching charger. Charging lithium chemistry in a random way leads to really interesting hard to extinguish battery fires. Ask me how I know. Should be a recommendation for optimum battery size either in the instructions or the plane specs. Too big makes the plane a pig to fly, (FYI: pigs don't fly very well) too small means you get a minute only of powered flight.

This is a good budget charger: https://amzn.to/46qj2a7

If you thought the 40A ESC included the battery then you are in for a bit of a shock. An appropriate LiPo battery will be many times larger and heavier! It may pose an installation issue in a flying wing.
Surely the kit included a recommendation for the motor and size of battery. If not then tell us the name and manufacturer of the kit and someone may have actually built one be able to advise.
Flying wings are not the easiest thing to set up correctly.

In 20 years of flying, I have not met a single pilot who flew on a wing for the first time. First, there should be flights on a trainer and in an aircraft simulator.

Part of being a newbie is you don't know stuff, some of which is sort of important. If you never experienced a stall....... "My plane just went up and down all by itself until it hit the ground and broke"
Maybe a 5 spar combat Zagi could work as a trainer, but even they are prone to spontaneously disassembling or spitting out their moving parts during rapid decel landings. Definitely cant tell if it's stalled except for the horrendous rate of sink, even in monster lift

Well, you have met one now! 😂 😂 My first successful plane was the FT Versa Wing...
I made the plane but the motor is too weak for it. Final dimensions are 140cm wingspan, 30cm root cord, 15cm tip, 31 degree sweep, weighs 450g.
I also put in a 2000mah 2S battery.
Stability and control isn't much of an issue, it flies for a few seconds at a low altitude but quickly drops. I can't get it to gain altitude even with my throttle all the way up. What motor would you recommend for this configuration?

First, make sure the prop is the correct way around. The numbers MUST be facing the direction of travel. In your case, the umbers must be facing the plane. If you had a tractor motor, the numbers would be facing away from the plane. If the prop is backwards, you will only get about 40% of the thrust.
Rather than change the motor, try changing the battery, try a 2200 3S. The extra voltage should make the difference.
On my wing, I use a 3536 1400kv motor. On 3S I have plenty of power, unlimited vertical, it will go fast. For your experience, look at a 2212 1000kv, maybe a 2830 1000 kv. You mostly want a lower Kv motor, it produces more thrust at lower speeds. A high Kv motor (2200) is for going fast but has far less thrust at lower speeds. With a lower Kv motor you will need a larger prop.
I go into more detail in these post.
Need some help comparing (and understanding) brushless motors
Hi all, I'm in search of a "C pack" compatible motor to to use on my C pack swappable. For reference, I fly the FT P40, FT Bloody Baron, and FT Simple scout, and I'll be adding an FT Mig-3 to the collection soon. I have been using FliteTest's 2218/1180kv Radial for years and am thoroughly...

Help! - Picking an appropriate motor, propeller, and ESC
This may not exactly be the right place for this, but since you guys hopefully know a lot more about electric motors than me maybe I can get some answers. This is kind of a loaded question, but if I were to go about scratch building a plane (not an FT plane), how can I know what kind of power...
