Introducing the best value charger for lithium-ion batteries such as 18650! It can measure up to four different types of rechargeable batteries. It also has a capacity measurement mode and a storage mode, and can even measure internal resistance, making it a very multifunctional charger! How do you use it? What are its functions and performance? I have investigated it to the best of my knowledge, so I will introduce it along with my personal opinion! *Error correction from 15:40 It is said that it is a 6R8 load resistor, but this is an inductor (6.8μH). It seems that the discharge is done by an electronic load using a semiconductor. The charger introduced this time was purchased on Amazon! ・18650 charger 4-type (VC4SL) 3,799 yen (as of 5/31/2024) https://amzn.to/3KJ9gpf It has many functions, so this one unit is usually enough!・2-piece type (VC2SL) 2,599 yen (as of May 31, 2024) https://amzn.to/3KqaKVe If you don't need up to four pieces, this may be a better value for your money! *This does not seem to have grad mode or store mode.
