Darn cold fingers?
A test for you:
It appears that the controller is not going to control Voltage at different throttle settings.
One of the things that needs to be checked out is if it controls current output as the batteries become charged in the same way an automatic battery charger would.
Here is where your ammeter will come in.

Ok so I have DC ammeter. I did as you say and put the clamp around the negative wire. At idle it put out
6 amps and at full throttle it put out a bit more than
70 amps. Thanks again.
CAREFUL here! You could blow up your batterie(s)!
Copied from the internet:
BATTERY CHARGE/DISCHARGE RATE
You’ll see references in battery books to the proper charge rate. C/10, C/20, etc. Sometimes it can be confusing. What you need to know is that it means the “time” it takes to fully charge a “dead” battery at a certain amp rate. For example: A 105AH battery will fully recharge (from dead) in about 10 hours at about 10 amps of charge (C/10) or about 20 hours at 5 amps of charge (C/20).
Faster charge rates, like C/5 or C/8 shouldn’t be used with most batteries because the high amperage required for such a fast charge damages the battery.
C/5 on a dead 105 AH battery requires pounding in over twenty amps. (This is sufficient reason to stay away from fast-chargers in service stations where a gigantic amount of amps are pummeling your battery when they “charge” (destroy) it in 20 minutes. And when you buy a battery off the shelf, don’t let the guy “put it on a charger for just a few minutes” or it will be damaged before you ever use it.
What you need to do is set the range extender speed so it is putting out around 29V while connected to the batteries and see what the current is.
