[Nut-upsuser] Shutdown time configuration

I switched a while back to a Cyberpower PR3000LCDRTXL2U UPS with an
external battery chassis.  We've lost power twice since I installed it,
and both times, the UPS has killed power to everything while still
indicating 80% capacity before NUT has even initiated shutdown on anything.

Here's what upsc reports on it right now:

battery.charge: 100
battery.charge.low: 35
battery.charge.warning: 20
battery.mfr.date: CyberPower Systems
battery.runtime: 2220
battery.runtime.low: 592
battery.type: PbAcid
battery.voltage: 53.8
battery.voltage.nominal: 48
device.mfr: CyberPower Systems
device.model: PR3000LCDRTXL2U
device.serial: PTEHU2000098
device.type: ups
driver.name: usbhid-ups
driver.parameter.pollfreq: 30
driver.parameter.pollinterval: 2
driver.parameter.port: /dev/ttyUSB0
driver.parameter.productid: 0601
driver.parameter.synchronous: no
driver.parameter.vendorid: 0764
driver.version: 2.7.4
driver.version.data: CyberPower HID 0.4
driver.version.internal: 0.41
input.transfer.high: 131
input.transfer.low: 102
input.voltage: 117.0
input.voltage.nominal: 120
output.voltage: 117.0
ups.beeper.status: enabled
ups.delay.shutdown: 20
ups.delay.start: 30
ups.load: 39
ups.mfr: CyberPower Systems
ups.model: PR3000LCDRTXL2U
ups.productid: 0601
ups.realpower.nominal: 3000
ups.serial: PTEHU2000098
ups.status: OL
ups.timer.shutdown: -60
ups.timer.start: -60
ups.vendorid: 0764

I don't think I ever got all the way through NUT configuration on it.
What am I most likely doing wrong, or what might I have missed, or what
setting am I misunderstanding, that the UPS itself is shutting off the
power so absurdly early?
