<div>How well are the cells balanced after parallel charging?</div>
<div> </div>
<div>Just curious since I don't do high amp parallel charging because of the balancing of cells in different packs. </div>
<div> </div>
<div>I also don't know how that parallel board from Revolectrix work. </div>

<div>It's not electrically possible to read each pack individually if they're connected in parallel. Thats why every so often you charge a pack by itself. </div>
<div><br></div>
<div>Some guys get all wrapped up and teary-eyed about parallel charging because they can't monitor each cell down to the 1/10000 Volt or MOhm every charge. </div>
<div><br></div>
<div>The guys that get all apoplectic about parallel charging typically have never tried it, or did something illogical like connecting a brand new fully charged pack in parallel to an old, tired discharged pack and then wonder why it didn't work. <br>

<div>I believe his question on RCU is if it will do it while parallel charging and give readings on each pack. </div>
<div><br></div>
<div>Will it do that? </div>

<div>Obviously he doesn't own one or is capable of reading the manual. When you start a charge, cycle thru the pages until you get to one that says "Calculating Internal Resistance(%)". After a few seconds, it shows all of the cells IR values throughout the entire cycle. <br>
