Isn't it better to use a lipo battery than to use an 18650 battery?

Well the battery setup is around $25 for 3400 MAH 32 volts, and they can output a fairly stable 250 watts. However I'm not very experienced with lipo batteries, do they have higher current?

Yeah lipo batteries tend to have higher discharge and recharge rates but have less capacity and slightly less voltage. Usually around 3.2v

I'm taking a look around. I came across some well priced 14.8V lipo batteries( I'll need 2). Are there any cheap chargers for these? Only option I see is a lipo balance universal chargers that are meant for any battery type. Aren't there any mass produced generic chargers for these?

I'm using eight 18650 batteries in this video and I feel the power is low.

Next time, I will use the lipo battery.
The lipo battery has more power than the 18650.

I'm using 8 Panasonic cells, but samsung 18650 has one that can give 40 amps. 40a X 32V = 1280 watts. That's a pretty reasonable amount of power!

I do not think so.
The 100W laser made by styro uses a lipo battery,
His 100W laser is much more powerful.

I'm putting out 250 watts(I have a meter that tells me the exact power usage), which is what the laser is rated to receive. Here are the high amp Samsung 18650s I was referring to. 8 of these cells would put you far over the rated amperage for that laser: https://www.aliexpress.com/item/4000473387460.html?spm=a2g0s.9042311.0.0.2be84c4d8hbjZ0


But yes, I do agree that lipo batteries will give more current. However, they have low capacity and cost more.

At Amazon in Japan, you can buy a 3S lipo battery 7200mAh for $ 55.
Is it expensive?

I would like to know the driver used in this laser.
I also want to use it.
Is it on ebay?
If so, can you tell me the URL?

Hey, it's a voltage step up/regulator from Amazon. Handles 600 watts. Careful though, the current control is finicky.. But it does work.

There was the same thing in the Japanese Amazon.

This display is AC powered
Can it be used for DC power supply?

You are getting away with a voltage regulator dc-dc converter because it and your cells can't output enough to hurt the array, you need a current regulator and more battery if you want to get max overdriven output or even the full 95w output, you are likely drawing 9-10a from your cells as they sag under load and your array is likely doing 75w max when it could do 95w rated and 110-125w overdriven if you can keep it cool, but 75w isn't bad if you can hold that 250w output as the cells discharge.
