make,%202.png +

+
+ +

+Simple charger and terminal (front-end) for 12V lead-acid battery. +

+ +

+Idea is to distribute power from rechargeable 12V battery to various +appliances (soldering iron, radio transmitters, etc..) while also +providing use-charging in the background. +

+ +

+Single on/off button disconnects battery and up-step voltage source +from front panel terminal connectors. +

+ +

+Tecnoiot MT3608 voltage up-step is used. 3V DC external power supply +is used to feed voltage up-step. Up-step is tuned to ~14.4 V. +

+ + +

+ +

+Current design is rather of blog (experience sharing) value. It has +quite some drawbacks: +

+ +
    +
  • Warning: Circuit has dangerous instability. Requires low voltage +~3V but relatively high current external power supply. Using +higher voltage but low current power supply could easily lead to +situation where step-up generated load pushes power supply output +voltage down too much. This leads to too much power being lost +within power supply and easily leads to power supply overheating! +
    • + +
  • There is no dedicated current limiter. 3V external power supply +and up-step are acting as current limiters. +
    • + +
  • While RCA connectors do work as DC power connectors, but are not +intended to be used this way and are not very reliable. +
