Compatible RC Models

This 7.4 V lithium-ion pack replaces the original battery in a wide range of EVX and VX series transmitters and receivers. The list includes EVX-530, EVX-531, EVX-534, EVX-539, EVX-231, EVX-261, VX-260, VX-261, VX-451, VX-454, VX-456 and VX-459. It also matches part numbers FNB-V133Li, FNB-V134Li, FNB-V138Li, AAJ67X001 and AAJ68X001. Buyers who need a different voltage or connector type should look elsewhere.

Capacity and Weight

Rated at 1500 mAh and 11.10 Wh, the cell delivers typical run-times for sport flying and driving sessions. The pack weighs 103.0 g net and measures 110.90 x 57.80 x 32.20 mm, fitting the existing battery compartment without modification. Rechargeable lithium-ion chemistry avoids memory effect and supports repeated cycles. Users who require significantly longer endurance per charge will need a higher-capacity alternative.

Direct Replacement Upgrade

This unit is a straight swap for the factory-supplied batteries listed above, restoring original run-time when the old pack no longer holds charge. The jump is worth it when the original cell shows reduced capacity, swelling or failure to balance. It does not add new features or increase voltage beyond the stock 7.4 V specification. Pilots seeking telemetry integration or smart-battery protocols must choose a different product line.

Questions about this item

How do I install the FYIOGXG 1500mAh 7.4V Li-ion battery into my EVX-530 radio, and what step do people often miss?

Slide the battery pack into the radio's battery compartment until the latch clicks securely; the step many miss is verifying the original part number FNB-V133Li or AAJ67X001 matches before fitting.

What maintenance or replacement will this 1500mAh Li-ion battery need over time?

As a rechargeable Li-ion pack, it will gradually lose capacity after repeated charge cycles; plan to replace it when runtime drops noticeably below the rated 11.10Wh.

What is the first limit I will hit when using this 7.4V battery continuously on high power?

The 1500mAh capacity and 11.10Wh energy rating set the runtime ceiling; sustained high-drain transmission will deplete the pack faster than standby use.
