Can I add multiple charging profiles to the delta Q provided by zero?  Or can I just reprogram it entirely to charge a 48v battery?  I am building an electric mower and I have 2 Chevy volt packs I will run in parallel.  My other thought is maybe I could just connect the batteries in series while charging and I wouldn't have to change anything on the charger presumably because it is setup for 96v lithium.  Any ideas?

It looks fairly customizable to me: https://delta-q.com/software-accessories/

I have seen all of that but still can't figure out how and if it can be changed from 96v to 48v.

Ah, I found a FAQ for "Can the amps be adjusted?" which says that no, they can't, and adds that the DC output voltage is not configurable.

So, that's disappointing.

What model is the DeltaQ charger you've got? is it a 72V version? or 48V version? The 72V range won't work with a 48V pack, it's too low.

Also, programming you'll need to find someone with the lithium profiles (I have them). I program for a fee, which is reasonable.

Well I don't need the amps adjusted, just the voltage.  My model is a 913-9600-01.  It's a 96v.  Can those be programmed to lower voltages?  If not what do you think about connecting the batteries in series during charging?

I only cited that answer because they answer your question in the same breath: no.

Connecting batteries in series in this case sounds sane to me, as long as you can make the equipment for it operate safely.

Ooops, sorry, somehow I missed that part. That's a bummer.  What are the differences in their programmable charging profiles/algorithms besides battery type if voltage cannot be adjusted?  I may just start with manually connecting the batteries in series at first then see if I can find a contactor that will disconnect the motor when it connects the batteries in series.  Obviously I will have the main contactor off when doing the charging manually but if someone were to turn the switch on/mower on I will either blow my fuse or the motor.

I know that "generic" Delta Q Chargers can be programmed but, can the Zero Delta Q program
be changed? If so, I would imagine that it would be to facilitate use on Non Zero applications.
IF the Zero Delta Q can be programmed, are there any "enhancements" that could be seen
if reprogrammed for use on the Zeros?

the voltage RANGE cannot be adjusted.

The end voltage is programmable. The problem is, the 96V and 72V chargers cannot go down that low. They have a range that does not encompass 48V. Lets say the 72V has a range of 60-100V, and 96V has a range of 80V to 130V. Neither can be used to charge a 48V battery. They won't turn on because the voltage is too low.

Well thanks for clearing that up.  Now I wonder if the zero delta q charger is really 96v or if it's been changed slightly.  I found a cheap charger on amazon.  It's called veribest.  Seems like a cheesy name but they sell a 48v 4A lithium charger for $90 so I may just go with that.
