http://evdl.org/pages/iotamods.html Another approach that will probably provoke some controversy here is to tap your battery at the DC:DC's nominal voltage. This will create an imbalance in the battery. How bad that imbalance is depends in part on how much power you need from your DC:DC. Yet another way to do it, crude and somewhat wasteful, might be to build a lossy regulator circuit to drop the battery voltage to the DC:DC's voltage. Here's still another thought. I have a slightly-used Todd PC20LV 96-volt DC:DC here, and also a used Curtis 1400E 72-96 volt DC:DC. Both were in working condition last time I checked (January 2019). You might be able to connect each to half the battery, and sum their outputs through diodes. Not 100% sure, but I think you can trim the Todd's output to try to balance them a little better, so they share the current more evenly. If you're interested in trying this, contact me off-list (see the bottom of evdl.org/help ). I'll let them go pretty cheaply.
