Options for mppt charge controller 60v battery bank

That all depends on what the cells are designed for. Look up the stats of the cells to know what they are rated for.

These are used cells that I want to charge to 4v max.. so I need a charge controller that can charge that high.. Sean says he uses victron and that it will charge to 64v even though it is a 48v charger.. so I was just curious if u knew of any other charge controllers that charged at that high of a voltage

I'm not familiar with the various charge controllers, but others are. Perhaps they'll chime in.

You could always drop down 15s and the PCM60x would fit your needs just fine. At 4.1V top voltage, that'd be a max overall of 61.5V

The Victrons are proven to be reliable and well documented. Overall, you get what you pay for when it comes to this type of equipment.

I can’t drop down to 15s due to 16s already putting my inverter at the lower end of its operating efficiency.. really I should have a 72v battery pack but I’m not going there

In the end you are going to have to have to sacrifice somewhere. Either can't fully charge your battery bank, or get slightly lower efficiency. This is the big problem with chargers/inverters being designed for lead acids and trying to use lithium based batteries instead (unless using LiFePO4 or similar).

I think if I can get the battery charged to 64v I wouldn’t lose much efficiency.. the battery pack is 16s 2p the pack is already together from factory.. it’s a Chevy volt 60v pack

Will I be able to adjust victrons settings thru my iPad? And can anyone verify that the 150/35 victron charges to 64v?

For my money... I am a VERY happy Victron user.  They seem expensive at first glance but you get a ton of value and support for the money plus they scale well if you stay in their eco-system.

If you wanted to save some cash you could look at the BlueSolar over the SmartSolar but I think you would be missing out on the best part of these units.  Build quality is also excellent and they dont inflate specs like seen in Chinese hardware.

Really any reputable brand is good, but they also have similar pricing.

What’s the difference between blue solar and smart solar?

SmartSolar is newer and has integrated Bluetooth for connectivity.  Logging, monitoring, setting changes from a mobile device.

BlueSolar can still do the same, but requires purchase of a Bluetooth dongle as a separate accessory.  

The savings are minimal, I always go with SmartSolar.
