18650 Charger from USB
swordson Apr 29,2023
The original schematic of this circuit is not mine. When you build the circuit, you will have made your own DIY lithium charger. The circuit has not been tested. However, it is likely to work properly. Correctly connect any USB power supply to the input pins. When the battery is full, charging will be automatically cut off.

4-cell 18650 Charging Module
MakerIoT2020 Apr 27,2023
Low BOM cost 4-cell 18650 ChargerDue to their high capacity and relatively low cost, LiPo cells are almost everywhere these days. This Low BOM cost 4-cell 18650 Charger module is my attempt to solve another issue.The 18650 Lipo cell is quite common in my lab, and for an excellent reason, as mentioned above, they are cost-effective and also store quite a bit of energy. recharging them after use has however been quite a lengthy exercise in the past.The usual process involved a few Lipo Charging mo...

Recycled 18650 battery pack PCB
CyberMouse Dec 26,2022
These PCBs were designed to connect and mechanically put together 18650 Li-Ion cells in to big battery packs. This exact design is meant for 12s9p battery pack but the design could be adjusted for different pack sizes and cell types (21700 for example). Cells are connected to the boards using thin tin plated copper wire which also acts as a fuse for individual cells, thickness of this wire needs to be adjusted to maximum amp draw of the battery cells used.I decided to build this project to be ab...

Charger 18650 Battery
Oct 07,2022
I builded a Lithium Battery Charger & Booster Module. I used a TP4056 Li-Ion Battery Charger IC and a FP6291 Boost Converter IC. The result is battery module for a single-cell Lithium battery that can be very useful for powering electronic projects. Since the most famous boards like Arduino, NodeMCU, ecc.. are regulated to 5V the purpose of my module is to safely charge a lithium battery and guaranteed a stable 5V output. For now i designed it with a charging current of 1A, and also the...

How to Balance a Battery Pack With USB or the Traditional Method - TP4056
Maurizio Miscio Sep 11,2022
Hi guys, today let's see together how to balance a battery pack through a very common micro-USB connector or with the traditional methodStep 1: Why Balance MattersWhen charging a battery pack it may happen that, once charged, measuring with the multimeter there is a voltage slightly lower than what we expected (such as 41.5 V instead of 42V).If so, then most likely, inside the battery pack, there is a cell (or several cells in parallel) that has a lower voltage than the others.This is a problem ...
