Hey everyone! I hope this isn't a repeat question, but I've been hearing a lot about the importance of top balancing new batteries. I have three EG4 wallmount batteries set up in parallel with a Flexboss21. How exactly should I go about achieving that? Should I charge each battery individually to 100% or since they're all connected, can I just turn everything on and let it handle the balancing on its own? Any advice would be appreciated!

When you have your batteries in parallel, it's pretty simple! Just make sure the voltage on each battery is close—ideally within 0.25V of each other. Once you've checked that, you can just power them on and charge them all to full. The batteries will balance themselves while charging, so no need to do it one by one!
Just to add on, if the voltages aren't close enough, it might create issues. Ideally, you'd want them to be within 0.05V on each individual cell, but 0.25V between the batteries is a workable range. If they're too far apart, though, it might be worth checking them individually before connecting everything.
