Battery care and storage

Daily use

• Charge at 1C on a balance charger — 1C is the pack's capacity in amps, so a 1300 mAh pack charges at 1.3 A.
• Land at 3.5 V per cell under load; a pack resting below 3.3 V per cell has been over-discharged.
• Let packs cool before recharging.

Storage

LiPos age fastest sitting full. If a pack won't fly within a day or two, store it at 3.8 V per cell (every balance charger has a storage mode). Store in a fireproof container, away from anything flammable, at room temperature.

When a pack is done

Retire a pack that is puffed, has a damaged wire or connector you can't service, drops noticeably more voltage under load than its siblings, or won't balance within a few hundredths of a volt. Condition beats cycle count every time — a puffed pack at 40 cycles is done, and a well-treated pack can outlive the estimate.

The Hangar's battery list tracks cycles per pack and shows a wear hint against a nominal 300-cycle life, so a pack at 150 cycles reads as roughly half used. Treat that bar as a rough prompt to inspect, not a retirement date.

Disposal

Discharge fully (a resistive discharger or salt-water bath over a few days), then take the pack to a battery recycling point — most electronics retailers and municipal hazardous-waste sites accept LiPos. Never bin a charged pack.

Shipping note

Batteries have shipping restrictions and are excluded from normal return post — see Returns, refunds, and RMA before sending anything containing a pack.
