I have a Tripplite SU series UPS that allows external batteries to be
connected to get longer run time in case of power outage. It gives
specs. of 30 amps, 36 volts on the external battery connection area
(so I assume Tripplite has 36 volts total from internal batteries).
I want to use some godzilla batteries, like three 12 volt car
batteries in series (which often give 13 volts or more each fully
charged).
I'm nervous about connecting though, because I already toasted my
DELTEC UPS connecting a 12 volt car battery to the internal battery
leads (I removed 12 volt internal battery first and then connected
using proper polarity, of course).
It seems such a powerful battery(s) makes like a large inrush upon
connection ?
It toasted two 30 amp fuses hard soldered on the circuit board.
Should I use a diode, or a resistor, or something to control/buffer
the "inrush" ? What specs would you suggest ?
