Balance Tags to the_content Words Length

I have a category page that I need to show some of the content of a the posts with HTML tags such as images.

Site - http://hoffwebsites.com/wp-hoff-testing/ms-conversations/

I have found this code that does the trick.

I have this in my functions.php

function technig_content($limit){$content = explode('', get_the_content(), $limit);if (count($content)>=$limit){         array_pop($content);         $content = implode("",$content).'...';} else {    $content = implode("",$content);}$content = preg_replace('/\[.+\]/','', $content);$content = apply_filters('the_content', $content);$content = str_replace(']]>', ']]>', $content);return $content; }

And this where I want to the code to go.

<?php echo technig_content(170); ?>

However, it is leaving open HTML tags sometimes that throws off the page structure in some case. Usually an open bold or italic or bulleted list.

I know there is Balance Tags - https://codex.wordpress.org/Function_Reference/balanceTags

But I do not know how to incorporate that with my code.

I have tried with no luck, any thoughts?

<?php echo technig_content(170); echo balanceTags($technig_content, true); ?>
