    DIY Lithium-ion battery charger

    Ummm, are my questions too hard or am I doing something wrong? No one has replied to any of my questions. Please advise me if I'm doing something wrong on this forum.Kind Regards.

    Hi Victoryking,greetings from down under, New Zealand.Thank you so much for your reply.I have seen so many videos of almost every configuration; parallel and series etc etc and some people connecting 1x 5V power supply to many PT4056 connected in parallel etc. It's quite confusing and scary actually, of what could happen! I've finally come to the conclusion after coming across a website last night, dealing with this whole subject, that yes, the PT4056 is safest (and as you stated) and meant for 1x battery only.So I've gone and bought a bunch of 5V/1A Wall power supply units to connect to each PT4056 individually. I feel confident and good about this whole area now. I should've just done that in the first place lol I was trying to find a way of getting out of buying a power source for ev...

    Please see diagram below:If I had 1x 5V/5A Ph Charger or Power Supply connected to just 1x PT4056 Module, but had all 5x PT4056 Modules wired in Parallel,Q.1. Would each PT4056 Module get 1A or 5A each?Q.2. If say 3x PT4056 Modules fully charge the 18650 batteries, will the remaining 2x 18650 batteries get 2.5A each? (1/2 of the 5A ea)Q.3. If say 4x 18650's are fully charged, will the remaining 1x 18650 battery get the full 5A?Please help me to understand what happens. Thank you :)

    Hi Everyone,I'm new to this whole "charging 18650 batteries" using the PT4056 Module. I've just bought 10x PT4056's and soldered them to 10x single 18650 battery holders.I have seen posts saying I can use a mobile phone charger at 5v/1Amp, to power the PT4056 Module.The questions I have are:1. Is there a formula to work out how many amps I need to charge more than 1x PT4056 Module joined in parallel? 2. If I joined say 5x PT4056 Modules together in Parallel, would I need a power supply of 5V with 5amps output?Please advise what I need to do. I look forward to your help.Kind Regards,Lance.

    Hi Everyone.Q. 1. Why do you have to "discharge" the batteries?Q. 2. At what stage do you have to "discharge" the batteries?Q. 3. With brand new batteries, do I have to "discharge" them first before I charge them?Q.4. How often do I discharge the batteries?Thank you in advance :)
