Low Temperature 4S 14.8V 8000mAh 100C LiCoO2 Pouch Battery for Winter Drone

Cold weather is where most pouch packs quietly stop performing. Capacity that looks fine on a bench at 25 degrees Celsius collapses once the pack is soaked at minus 20, internal resistance climbs, voltage sags under load and the flight controller triggers an early landing. The LPW-LT4S8000 was engineered around that exact failure mode. It is a 4S 14.8V 8000mAh LiCoO2 pouch battery in which the electrolyte additive package and the electrode coating thickness have been re-balanced so that ionic conductivity is preserved at low temperature instead of being traded away for room-temperature peak power.

Practically, that means a pack that still delivers its rated 100C continuous discharge in a cold soak, keeps a usable share of its nominal capacity below freezing, and does not need to be pre-warmed in a vehicle before a pre-dawn launch. For survey teams, inspection crews and search and rescue units working in winter conditions, this removes a step from the pre-flight checklist and, more importantly, removes the risk of a mid-mission voltage collapse.

• Cold-rated electrolyte system: stable discharge from minus 25 to plus 60 degrees Celsius, verified by a 4-hour cold soak test at minus 20 before capacity measurement.
• 100C continuous discharge: an 800A continuous rating from an 8000mAh cell stack, with 150C burst capability for take-off and aggressive attitude recovery.
• LiCoO2 cathode construction: lithium cobalt oxide chemistry keeps the energy density high in a slim pouch format, so capacity is gained without adding pack volume.
• 800 cycle service life: capacity retention above 80 percent after 800 full charge and discharge cycles at 1C, which lowers the cost per flight hour over the life of the pack.
• Matched harness options: T plug, XT60, XT90, AS150, JST and TRX connectors are available, with the AS150 and XT90 harness specified for the full 100C rating.
• Slim pouch footprint: 165 x 56 x 32 mm and approximately 690 grams, so two packs fit side by side in most 10 to 13 inch frame battery bays.
• Integrated balance lead and cell matching: every pack is built from cells matched to within 15 milliohm internal resistance before assembly, which keeps the pack balanced through its service life.

Harness note: the full 800 A continuous rating requires the AS150 or XT90 harness. Packs ordered with an XT60, T plug or JST harness are limited to 60C continuous by connector thermal rating, which is still sufficient for 5 to 7 inch airframes.

This pack is aimed at operations where the launch happens before the ambient temperature has recovered. Typical deployments include winter power line and pipeline inspection, pre-dawn mapping and photogrammetry sorties, high-altitude survey work where air temperature drops roughly six degrees per thousand metres of climb, cold-climate search and rescue standby aircraft, and agricultural spraying in early spring. It is equally suited to fixed wing and multirotor platforms in the 4 to 8 kilogram all-up weight class, and to ground vehicles that share the same 4S architecture.

Every pack ships in an anti-static bag with a flame-retardant foam cradle inside an export-grade corrugated carton, forty packs per carton, with the state of charge set to approximately 30 percent in line with air freight requirements. Each production batch is sampled for capacity, internal resistance, cold-soak discharge and a 1.2 metre drop test on the packaged unit, and the batch test record is issued with the shipping documents together with the UN38.3 report, MSDS, CE and RoHS declarations. Packs are covered by a 12 month warranty against manufacturing defects, and custom voltage, capacity, harness and label configurations are available from a two unit minimum order.
