I have one as well at my shop. My point is, you can certainly make a nice set of buss bars with a simple hand drill.

Why do you need to buy a drill press? You can simply use a hand drill.

Thanks for that Snoobler. I just got off the phone with Ian from Watts247 and he suggested to set the bulk and float charging volts to the same level. I will do this to fully charge the bank and do a capacity test and once complete, adjust both to where I would like to top off the battery to...

Charging my battery pack for the first time and the MPP Solar seems to only get to the float voltage setting and then stops charging. I have the Bulk charging set to 28V and the float set to 27.2V I have the BMS set to 80% duty cycle (Overkill Solar) and the cells are showing 3.4V which is 80%...

Well, I got it wired up and charging. Edit: I just read that the cells are now starting to balance.

Use studs instead.

I've already read the guide and watched Will's videos before I posted here. I guess you guys are saying to top off the cells to about 3.5 volts with the MPP Solar charger and then top them off with the desktop power supply?

What power supply are you using?

Would you guys hook up one of those $60 bench top power supplies and leave it unattended for days at a time? I'm in no hurry to top balance the pack, but (8) 280Ah cells is going to take a while and I work for a living.

The Overkill BMS already has built in cell monitoring. I know it only measures voltage but that doesn't really tell the SOC does it?

I don't mind the 5 days of charging with a $60 10 amp charger, but I don't want to leave it unattended the whole time just in case the magic smoke appears while I'm at work.

I connected them all in parallel to get them all @ 3.3V. I don't have a bench top power supply and even if I did it would take a long time @ 10 amps for any reasonably priced charger. My MPP Solar all in one unit has a built in 25 amp inverter/charger. Can I just plug it in on my bench and...

None of those listed are 280 Ah

A shunt will read SOC from the whole pack.
