Quick verdict: The Just Drones team has put the Lite 640T on two billable inspection jobs since pickup — solar panel scan and a school roof thermography for an insurance brief. Verdict: compact thermal that punches above its weight at a fair price.

Autel EVO Lite 640T review
What’s good about it
Thermal-visible fusion in real time
On-screen overlay of thermal and visible is responsive and clean. Identifying a hot spot on a roof or in foliage takes seconds.
Compact body means two-person ops are easy
Sub-1kg with case. Two team members deploy from a car boot to flight in under five minutes — important when you’re billing hourly.
40-min flight time is the longest in compact thermal class
Real-world ~33 min. Long enough for an entire structure scan on a single battery.
Significantly cheaper than DJI Mavic 3 Enterprise Thermal
Around 30% less for similar deliverables in most scenarios. The maths works out fast on the second or third job.
What’s not so good
640 thermal is the lower commercial tier
Better than 320 but below 1280. For tight inspection — roof tile cracking, electrical termination — you may need the higher-res Max 4T.
Wind tolerance is modest for a thermal platform
Above 30 km/h you start loosing positional precision.
Software ecosystem is smaller than DJI's
Pix4D and DroneDeploy support is there, but third-party plugins for thermal lag DJI’s by months.
Battery cost is significant
$580 each from Autel direct. Plan for three minimum if this is a billing platform.
Who should buy this
Solar inspection, building thermography, agricultural water-stress, low-cost SAR.
Who should skip
You need high-res thermal — buy the Max 4T. Or pure visible mapping — Mavic 3 Enterprise RTK.
Heads up: the buy button above goes to Amazon Australia with the Just Drones team’s affiliate tag drones02-22. Costs you nothing extra; pays for the gear we crash during testing.
