Step 2: Automatic Charger With Arduino UNO:

The source code for the program made with Arduino UNO, through which you can charge battery connected 2 by 2 in parallel alternately, without having to be disconnected separately.

//In this time charge another one batt. Total charge time for every battery 15 hours.

During testing process under real conditions was observed that the resistance of the water in a large pool is much more than that of a bucket of water. 20 A input fuses were not enough. Use 25-30 А as main fuse. After that i choose to upgrade the schematic.I make changes to control the IC generator and remove the relay which interrupt high voltage after the transformer.

Step 5: Fails and Explosions:

Use high voltage fuses. :)

Of course you know that electrofishing is illegal in most juridictions.

Yes,fishing with this is illegal.I wrote this info in the begin of the article.I just assemble different shematics from diferent sources ,make tests and place it in one article.This is for educational suposes,you can use it for electolising the water and make flamable gas or make diferent chemical reactions to oxide the metals.It's your choose what will be used the device for.It's on your own risk.
