Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

The seller knew I was after one and very kindly informed me when they came back into stock so now have a Flywing Bell 206. Fantastic bit of kit. Well worth the wait.

Key Specs
About this product
FLISHRC 5200 mAh 35C 6S 22.2 V LiPo helicopter battery — a high-discharge lithium polymer flight pack engineered for FLISHRC scale RC helicopters. Fitted with the factory FLISHRC connector layout (XT60 power lead with JST-XH balance lead) so it drops straight into compatible airframes with no rewiring.
This is a helicopter battery — the high C-rating (35C continuous) is sized for the inrush current peaks a collective-pitch rotor head produces at full-positive. It is not intended as an RC car or buggy pack; the form factor and discharge curve are tuned for rotor-driven aircraft.
Specification
- Capacity: 5200 mAh
- Cell count: 6S (22.2 V nominal, 25.2 V fully charged)
- Discharge rate: 35C continuous
- Power connector: XT60
- Balance connector: JST-XH (7-pin)
- Chemistry: LiPo (lithium polymer)
- Manufacturer: FLISHRC (the OEM pack used in the factory RTF kits)
Compatible aircraft
Fits all FLISHRC 500-class V2 RTF kits and parts assemblies — AH-1 Cobra, AH-6 Little Bird, AH-64 Apache, A109, Airwolf, AS350 Squirrel, BO105, EC135, MD500D, MD500E, UH-1 Huey, UH-1N Bell 212, UH-60 BlackHawk, HH-60 JayHawk and SH-60 SeaHawk. Also the supplied flight pack with the AH-64 Apache RTR. The 5200mAh capacity gives the longest flight times of the FLISHRC 6S range, at the cost of slightly higher airframe weight than the 4300/4500 packs.
Charging and storage
- Use a balance charger set to LiPo, 6S, charge rate capped at 1C (5.20 A) for longest cycle life.
- Storage charge to 3.80 V/cell if leaving the pack longer than a week.
- Never charge unattended; never charge a swollen or damaged pack.
- Store and charge inside a LiPo-safe bag or fireproof container.
