LiPo storage charge
About 3.8 V per cell (roughly 3.80 to 3.85 V) for storage of more than a day or two.
Battery care guide
Drone battery care for Indian conditions.
By the NVX engineering team, New Delhi
The battery is the most expensive consumable on most drones and the most common cause of mid-air power loss. Lithium batteries hate heat, full-charge storage and deep discharge, and Indian summers make the first problem worse. These habits make packs last longer and fly safer.
Storage voltage
The single most important habit for battery life.
Li-ion storage
Store at roughly 40% to 60% charge; check your manufacturer's guidance.
Smart batteries
Many camera-drone batteries self-discharge to storage level after a set number of days; check the setting in the app.
Never store full or empty
Full packs age fast and swell; empty packs can fall below a safe voltage and become unusable.
Safe charging
Most battery fires start during charging.
Use the right charger
Original or correctly configured balance chargers only, with the right cell count and chemistry.
Cool before charging
Let a hot pack cool to room temperature after flying before charging.
Never unattended
Charge on a non-flammable surface, ideally in a LiPo-safe bag, away from anything that can burn.
Balance charge
Use balance charging so all cells stay at matched voltage.
Do not overcharge
Stop at the rated full voltage; do not use fast charge rates the pack is not rated for.
Heat and Indian summers
Heat speeds up ageing and raises fire risk.
Never leave packs in a car
A parked car in summer gets far hotter than the air outside.
Keep them shaded
Store packs in an insulated bag in the field and out of direct sun.
Fly shorter in heat
Land with more reserve; hot packs sag and lose capacity faster.
Cold mornings in the north
In winter, warm packs to room temperature before flight for proper voltage.
Swelling and when to retire a pack
A puffy, soft or bloated battery has gas build-up inside and must not be charged or flown. Take it out of service, keep it in a fireproof container away from flammables, and dispose of it through an e-waste or battery recycler. Also retire packs with large cell imbalance, physical damage, very high cycle counts or sudden voltage drops in flight.
Travelling with drone batteries
Airlines treat lithium batteries as dangerous goods. Spare lithium batteries generally must go in cabin baggage, not checked bags, with terminals protected. Watt-hour limits and approval rules vary, so check your airline's dangerous goods policy before you fly, and carry packs at storage charge. For road and courier shipping, use the carrier's lithium battery rules and protective packaging.
FAQ
Drone Battery Care: common questions
What is the storage voltage for a LiPo drone battery?
About 3.8 V per cell, roughly 3.80 to 3.85 V.
Why is my drone battery swelling?
Usually from heat, overcharging, deep discharge or long storage at full charge. Stop using it and dispose of it safely.
Can I charge a battery right after flying?
Let it cool to room temperature first; charging a hot pack shortens life and raises risk.
Can I carry drone batteries on a flight in India?
Spare lithium batteries are generally allowed only in cabin baggage, within the airline's watt-hour limits. Check your airline's dangerous goods rules before travel.
How long does a drone battery last?
It depends on care and cycles. Heat, full-charge storage and deep discharge shorten life most.
Can NVX check my drone battery?
Yes. NVX diagnoses battery and charging issues with safety-first handling. Do not courier a swollen battery; contact us first for guidance.
