For Sale - Custom made lithium batteries - Eon Lithium

Ok, 72v pack... I would probably being me go with 20 instead of 19, better a wee bit more than half a shot less (19x3.7nominal puts you are 19.46ish cels to make it happen, I would just bump over and let it ride)
the amperage you want will required .. a LOT of batteries at 72 v. The cumulative of your first Set is gonna be.. 72v at whatever mAh it is places with, so Ok, I am not looking up that cel, Still covid strong here, past the worst of it and just to the low energy I feel like poo stage. So call it mAh per cel, that is gonna be 2.5Ah (if I can still math) so 4in parallel to hit 10Ah, so for 25Ah you will need (counts on fingers) 10 sets of 19/20 cels.
that is 190 cels minimum.
Dude, this is a REALLY big package.
That is over 15kg once put together with all the fixings...
Now I am a big guy, not a lot of big stuff really impacts me, but slinging a 15-20 kilo pack seems a bit excessive and it sure as hell isn't gonna fit in the space you are talking.
Since it is a metric based battery, let's go with a real measurement system and stick to metric.
16x8x3.5
407x204x89
That is 18mm across, by 650mm high.
stack 2 up side by side and you are 40ish
over under and you are at 13
I do not see you putting 200 cels in that space, Unless he has a cel smoosher it just is not real feasible.

the wee 21cel package I work with all the time is like 4x8ish, and it weighs in substantually (people keep asking to reduce the weight and increase the Ah.. I just inform them in my best Scots "I canna change the laws of physics" leaving them very confused.

and for the battery is not terrible. base price for that many batts is like 475ish, and that is just the naked cels (bought new at factory bulk pricing) but honestly most people ain't buying in enough volume to hit that, so you are looking at 20-50% more for the bare cels. The rest of the kit is just in the minors, so 50-80 bucks all in, leaving you to pay for labor.

Also, is this a US company? because that many cels becomes touchy to ship, I mean just the bloody weight is gonna be expensive, if he is shipping from China... that is a whole other kerfuffle (I have a management company I hire to deal with it, because they pay the right bribes or something and my stuff always arrives in a timely fashion, before when I was all "I have ran companies, I can handle some shitty import paperwork" it took me a year to get my shit, and I had to pay them to store it...

I ain't an Engineer, I am just a guy who started playing with Batteries, and am only here because my son was all "Dad, why don't we get an E-bike" My childhood was redolent with the smell of cooked circuit boards, I have done let the smoke out of all kinds of things, the parental units were just glad I switched to electronics after the whole "5 gallon bucket of black powder" event involved 3 bomb squads and national news...

Batteries are an integral part of electrical energy. Not only do these store energy, but they also deliver power to the appliances. In recent years, an increased demand for electric vehicles has created the need for new-age batteries like lithium. Many emerging manufacturers are producing cheap lithium batteries for various electrical purposes. The purpose is to reduce the cost of electric devices like EVs, Solar systems, and daily use devices. This article will explore manufacturers making cheap lithium batteries that are affordable and reliable for powering your devices.

 

Part 1. What determines the price of lithium batteries?

Many factors collectively determine the lithium battery price. Each process adds to the price of lithium batteries from raw materials to the seller. Let&#;s discover why it is always hard to produce cheap lithium batteries.

• Raw Material is the most important and deciding factor in the price of lithium batteries. Lithium, cobalt, and graphite prices are high, contributing to the total lithium battery price.
• Manufacturing Process is another factor that determines the price. Suppose a manufacturer produces batteries at a larger scale. In that case, the manufacturing cost can be lower than that of small-scale manufacturing. Therefore, large-scale manufacturers often provide cheap lithium batteries.
• Supply and demand determine the prices of lithium batteries. An increased demand causes a shortage of the product, and as a result, price increases. On the contrary, high production and low selling will provide cheap lithium batteries.
  

Part 2. Types of lithium batteries

Lithium batteries come in many types and have different characteristics. However, there are three common types of lithium batteries as follows.

Lithium-ion (Li-ion) Battery

Lithium is a rechargeable battery that utilizes ions to move during the charge and discharge process. It has a very high energy density and a high-efficiency battery. It is ideal for low-weight devices, like laptops, mobile phones, power tools, RCs, wearable devices, etc.

Lithium Polymer (Li-Poly) Battery

A lithium polymer battery utilizes polymer electrolytes instead of liquid electrolytes. It is a semisolid battery with a compact and high energy density. Mostly used in mobile devices, drones, RC vehicles, and medical equipment.

Lithium Iron Phosphate (LiFePO4) Battery

This type of battery utilizes iron and phosphate instead of nickel and cobalt. It provides energy at a specific rate, which is best for a long lifespan. The size and weight of these batteries are greater than those of other lithium batteries. However, it is compensated in the form of cheap lithium batteries.

Part 3. Which lithium battery is the cheapest?

As discussed earlier, lithium batteries come in many types according to build material and characteristics. Many high-density batteries utilize costly materials like nickel-cobalt-aluminum (NCA) or nickel-manganese-cobalt (NMC), making a pricy choice. If you are looking for cheap lithium batteries, these can be expensive on your budget. On the other hand, lithium iron phosphate ( LiFePO4) batteries are cheap due to their iron and phosphate usage. LiFePo4 batteries are bulky compared to Li-ion or Li-poly but can deliver constant energy for a long time. Therefore, if you are looking for cheap lithium batteries,  lithium iron phosphate maybe a better chioce.

 

Part 4. Are cheap lithium batteries bad?

Cheap lithium batteries are not inherently bad, but they often come with trade-offs and potential risks. Here are some key points to consider:

Pros of Cheap Lithium Batteries

• Cost-Effective: They are more affordable, making them accessible for budget-conscious consumers.
• Sufficient for Low-Demand Applications: For devices that don&#;t require high performance or long battery life, cheaper options may be sufficient.
  
• Availability: Easier to replace due to lower costs, leading to minimal impact if they need to be replaced frequently.
  

Cons and Risks of Cheap Lithium Batteries

• Quality Control: Lower-priced batteries may suffer from inconsistent manufacturing standards, leading to potential defects or performance issues.
  
• Shorter Lifespan: They typically have a shorter lifespan and fewer charge cycles compared to higher-quality batteries.
  
• Safety Concerns: There is a higher risk of issues such as overheating, swelling, and even fires if the batteries do not meet strict safety standards.
  
• Lower Performance: They may have lower energy density, meaning they store less energy and may discharge more quickly under load.
  
• Warranty and Support: Cheaper batteries often come with limited or no warranties, and support from the manufacturer may be minimal or non-existent.
  

Considerations When Buying Lithium Batteries

• Reputable Brands: Opt for well-known brands with good reviews and a track record of reliability.
  
• Certifications: Look for batteries that have passed safety certifications like UL, CE, or RoHS.
  
• Reviews and Ratings: Check user reviews and ratings to gauge the real-world performance and reliability of the batteries.
  
• Intended Use: Consider the specific requirements of your device. High-drain devices may require higher-quality batteries to perform optimally.

While cheap lithium batteries can be suitable for certain applications, they often come with increased risks and reduced performance. Weighing the pros and cons and considering the specific needs of your device can help you make a more informed decision. Investing in higher-quality batteries from reputable manufacturers can provide better safety, performance, and longevity in the long run.
