Hi,

I have 18650 battery from LG (LGM26)
Some people said the battery is highdrain batttery, but others said the battery is not a highdrain battery.

Please tell me, how to categorized the high drain battery....?
If battery has high C then we call it high drain battery, but how much C rate?

Thanks
 
I found a couple of vendor listings and both say it can deliver 10amps max. I would say this is medium, 20-35amps is a typical "high drain" in my book.
Hi Thames happy to see your answer.
So basically there no any international standard to clasify the minimum requirement of high drain battery ?

I know of no standard. A few years ago 20amp was pretty common for power tool batteries. Now you can get 35amp. Why concern about what they are called, when more important is, will they meet the load demand? (really, I am asking)

How many cells in parallel do you plan to have? You will need about 70 amps to hit 5kw. When you select a cell, you must pick between amp hours and discharge amps, or some balance. If you are going to have at least 8 in parallel, a 10 amp cell would be okay. If fewer than 8 in parallel, get a 20 amp cell. If you are going to be demanding the full 5kw output in short bursts, you might get by with less amps and more amp-hours (range). The second option below is a good blend of cost, amps, and amp-hours if you have 8 or more in parallel.

Some examples below
10amp 3500mah
10amp 3200mah
20amp 2500mah
