Electronic Hobby

These BMS PCBs are great for LiOn 18650 battery projects. One important thing to keep in mind when working with these PCBs is that they are subject to electrostatic discharge. So it's important to always have a ground strap on the ground or touch the nearest metal tap to discharge the charge built up in the body. This practice minimizes the likelihood of damage to these boards during handling.

Pros
  • Pretty Package
Cons
  • I'm Silent

You need an adapter to activate it, as useless as a battery

Obviously charging current is needed to activate the circuit. If I understand correctly, the battery (3 18650s included and connected through these circuits) needs an input current before it can supply current. So far that corresponds with my experience. If I have to apply power from the adapter to this battery before it will function as a battery, then this is a truly horrible battery. Completely useless outside. Maybe I'm missing something here? (Help)

Pros
  • Certified
Cons
  • not reliable

Apply charging voltage when using for the first time.

worked wonders! Our nursing home feeders powered by 12V, 2A lead-acid batteries have been upgraded to 18650 lithium batteries. Tested for a week, discharging a home-made battery for a week and charging it several times in our baxter infusystem for feeding before using it send back to the hospital. Floor completed for patient use 5, 10 units left. Just remember that they need to be charged first before they start working. For security reasons, they made it work the first time. There is no output

Pros
  • nice thing
Cons
  • some problems

They work very well but there is something odd about the pads.

Others have complained that current is charged to the battery to keep it conducting. I mean I'm okay with that haha. I can't think of a scenario other than mass production where you build a backpack and then ship it and demand it work without even charging it once. I got my batteries from the website and did they come in 3.1 or 3.2V? For example, yes of course I will charge it before using the package haha. Anyway, the reason I'm giving 4 stars instead of 5 is because there is a loose metal…

Pros
  • Few competitors
Cons
  • Not satisfied
