    building a multi charger.

    Hello I was wondering if someone with more knowledge then I would be so kind as to help me with a project i'm playing around with.

    I have multiple 18650 Li-Ion that I use for my vaporizer and I thought it would be a fun project to build a multi charger for them. I got these from other 2 pack bundles that have the smart chip on them and a 3 prong plug. I would like to build a board that i can plug these 3 prong plugs on to and wire that to a battery harness so i can charge multiple sets at a time.

    I dont know where to start but here are some specs on the batteries

    voltage 3.7
    charging 4.2 volts
    i think they have a capacity of around 1200 mAh but im not sure

    another side project i would like to do would be to be able to test the capacity of these batteries so i know if they fall below 1200 mAh so i can recycle them.

    any help would be greatly appreciated.

    ill include pictures of the batteries and anything i can find that will help people see what im talking about.


    this is the type of battery holder i was thinking of

      DIY: Modified smart charger for all types of batteries
      by dbuergi
      Hi all,

      sometimes i'm in need of a charger / tester for very small batteries and even if my multimeter doesn't show anything there is a chance that a smart charger helps to revieve. I'm happy with my Keenstone smartcharger and i made a small mod just to use it with smaller batteries like in smartwatches or even camera batteries with special contacts.

      Soldering wires on the charger contacts and using needles as probes. I covered both with a shrink hose with integrated solder.

      Cyberpower cps1500avr not charging batteries
      by carrzkiss
      Hello, all.

      Cyberpower Battery Backup Unit.

      I bought two new ML18-12 batteries through Amazon (They have already refunded my money for the two batteries as we thought the batteries might have been bad.)
      When I got them in, they were not fully charged. I connected them to the UPS and waited 24 hours before connecting any networking equipment.
      In parallel, they read 24v, but within 24 hours, the meter on the front of the unit dropped from 4 to 3 bars on the battery charge indicator.
      Checking the voltage, it was down to 22v.
      I quickly removed everything...

      Modification of a Fluke multi meter that uses three AA batteries to use a 14500 lithium ion battery
      by sam_sam_sam
      I have had with regular AA batteries that leak this meter is expensive new I already replaced the battery battery clips once and the same thing happened again and I am tried of so it is getting modified to accommodate lithium ion batteries that are the same size excluding the positive terminal and removing the battery clips I will have enough room for the BMS protection board

      I going to put 3 lithium ion battery in parallel with the BMS protection board and a way to charge the battery externally and heat shrink the battery pack and use a JST connector so I easily remove the battery...

      how to prevent a connected charger from draining battery when not charging?
      by flat-earther
      I have an RC radio handset(Taranis QX7) which doesn't have internal battery charger which means I had to remove the battery every time I needed to charge it.
      So to improve it, I added a 15W USB-C charger board(link) inside and soldered it to the same connector on the PCB where the battery plugs into, great, now I can simply charge it with a USB-C cable.

      but the problem I found is that after the radio sat for two weeks without being used the 2S 18650 battery that I'm using was at 4.2V!
      So the battery is backfeeding the charger and being drained.

      How can I prevent...
