Third Reality 3RSB015BZ not reporting Battery Percentage

[darkxst]

What happened?

I am testing a Third Reality Smart Blind 3RSB015BZ and it is reporting that it is connected to mains power.

The following call is failing in the configure phase:
await reporting.batteryPercentageRemaining(endpoint);

I tested with an external converter and removing that line appears to resolve the issue and the battery percentage is reported correctly.

What did you expect to happen?

This is a battery powered device and should report the battery status.

How to reproduce it (minimal and precise)

On Joining the blind to Zigbee2MQTT there is a configure error.

This is my external converter code that I am testing with and appears to be working:

const fz = require('zigbee-herdsman-converters/converters/fromZigbee');
const tz = require('zigbee-herdsman-converters/converters/toZigbee');
const reporting = require('zigbee-herdsman-converters/lib/reporting');
const extend = require('zigbee-herdsman-converters/lib/extend');
const e = exposes.presets;

const definition = {
        zigbeeModel: ['3RSB015BZ'],
        model: '3RSB015BZ-Custom',
        vendor: 'Third Reality',
        description: 'Roller shade',
        fromZigbee: [fz.cover_position_tilt, fz.battery],
        toZigbee: [tz.cover_state, tz.cover_position_tilt],
        meta: {battery: {dontDividePercentage: false}},
        configure: async (device, coordinatorEndpoint, logger) => {
            const endpoint = device.getEndpoint(1);
            await reporting.bind(endpoint, coordinatorEndpoint, ['genPowerCfg', 'closuresWindowCovering']);
            await reporting.currentPositionLiftPercentage(endpoint);
            try {
                await reporting.batteryPercentageRemaining(endpoint);
            } catch (error) {/* Fails for some*/}
        },
        exposes: [e.cover_position(), e.battery()],
}

module.exports = definition;
