I did a test-fit of the case into the van.......smidge too wide....so I spent the last hour and a half making it skinnier.
No plan survives contact with the van/RV.

While I'm waiting for a few parts.....namely crimp terminals.........let's talk top balancing.....
I have a 60A Intellepower 9160 series RV charger, it outputs up to 60A at 13.6V.
I also have a fairly generic lab bench supply with a max amperage output of 5A.
My plan is to assemble the pack with the BMS, charge it with the intellepower to 3.4 volts per cell (13.6V for 4S), then rewire cells in parallel and use the bench top power supply fine tune top balancing at 3.5 3.55 volts or so.
The cells arrived all charged at 3.29V and I'm thinking it'll take a month of Sundays to get to 3.4+ volts per cell with the 5A lab power supply.
......is this a bad idea?
Thanks......I've been reading here on the forum tonight......either 3.6 or 3.65V seems to be the target voltage. I get the idea that you want to balance a bit higher than your max BMS voltage cutoff...so there is less chance of a cell wandering as you pass through say 3.5 or 3.55 volts in normal operation.
I upgraded the stock 130A econoline alternator to a 200A alternator........the new one had a tag on it that rates it at 130A at idle. The van consumes about 60-70A idling.....checked with my clamp-on ammeter.......it's a 2008 so headlights are on all the time. So I have 60+amps headroom at idle.Very nice set up!
How many Ah is your alternator rated for and which Victron DC-DC charger did you buy?
I am getting ready to order a Victron DC-DC charger for my truck to charge my EVE LF280K battery in 4s configuration.
Thanks for taking the time to post all your stuff!
