I'm no expert, but I just
move forward.

It depends on current, but usually the reserve capacity is a good rough
estimate in normal golf car use. For example, a T105 type battery with a

If you are using "GC2" style 6 volt golf cart batteries, they are
usually rated in "minutes" of 75 amp draw (Mine are 107 minutes).
They are rated at 208 AH (if you draw them down over 20 hourswhich
is unrealistic) and can probably deliver 110 or s
Lee,
Thanks for setting me straight that the backlight draws so much power that it
is better not to use a zener.
An ordinary buck converter can be OK if both the meter power and measurements
are connected only to the pack,
since then no chassis connection exists. For 48V packs the universal power

Continuing to cogitate on ebike batteries: can anyone give me a good
estimate of the number of ah one can pull from a lead golf cart
battery? I'm thinking my 2 20ah ebike batteries are a pretty good
fraction of a lead pack. Can you keep a lead GC battery alive if you
pull 100ah from it?

Yes, but it does not provide an ~isolated~ supply.
