LM358 3.7 Battery Charger
🙂 Jul 21,2020
This project is for a person who likes to build electronics circuits, obviously we can find other solutions for charging a 3.7V battery, much more cheaper and also using SMD components, which means that the board has smaller dimensions. This circuit is easy to be build, it uses regular components that we can find them very easily; it has 2 LEDs which indicates when the battery is fully charged or not. P.S. I am not the original author of this.

18650 PowerWall with Onboard BMS
van der Walt Mar 04,2020
Details: https://openhardwarecoza.wordpress.com/2020/03/05/diy-18650-powerwall-with-onboard-bms/This is based off the 18650 Powerwall projectIncludes onboard BMS circuitry to protect and balance charge the cells. Modules are stackable with 25mm brass M3 Hex spacers, to build packs up to 100aH Balance connectors provided if you want to you can skip adding the Balance charger circuitry and instead use your own like Batrium, Orion, etcOnboard cell protectionUndervolt disconnect (2.9v per cell)Overv...

Arduino Battery Capacity Tester V2.0
Green Energy Nov 10,2019
Nowadays fake Lithium and NiMH batteries are everywhere which is sold by advertising with higher capacities than their true capacity. So it is really difficult to distinguish between a real and a fake battery. Similarly, it is difficult to know the capacity retained in the salvaged 18650 laptop batteries. So, a device is required to measure the true capacity of the batteries.In the year 2016, I have written an tutorial on " Arduino Capacity Tester - V1.0 " which was a very straight for...

1S8P Modular Powerwall Board
Cabanayan Jr Mar 08,2019
1s8p boards are use for Powerwall, these boards are modular.You can create from 1s to 14s system.To increase AH capacity, just connect the boards in parallel.To increase Voltage capacity, just connect the boards in series.Board uses very minimal components:2x - 4s 18650 battery holders8x - SMD fuse4x - StandoffsOptional:Fuse holdersOther details:These boards are designed to be installed using a nylon guide for swapping.
