Direct replacement for Spektrum transmitters

This 9.6V 2000mAh Ni-MH pack matches the original specifications for the XP9503, X9303, XP8103A, XP9303, XP7202, XP6102, XP662, DX7, DX6, XP9103 and JR 11X models. It also fits the JR-2S, JR-2, JR2, JRPB5011, SPM9521, JR-A and JR2S part numbers. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits.

Capacity and headroom

The 2000mAh rating delivers 19.2Wh of energy for extended transmitter sessions. Ni-MH chemistry provides stable voltage output through most of the discharge curve, but capacity will diminish if the pack is stored fully charged for long periods. Runtime drops noticeably in cold conditions below freezing.

Dimensions and certifications

The pack measures 98.0 x 29.0 x 29.0mm and weighs 282.0g, matching the original form factor for a secure fit in the transmitter battery compartment. It carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications. Verify your transmitter model and part number before ordering.

Questions about this item

Will the 9.6 V 2000 mAh pack fit my older DX6 transmitter that originally used a JR-2S battery?

Yes, the replacement is listed as compatible with the older DX6 and matches the JR-2S part number, so it will fit and power that transmitter.

How can I confirm the battery is delivering its rated 9.6 V and 19.2 Wh after the first charge?

Measure the pack voltage with a multimeter; a fully charged Ni-MH pack should read at or above 9.6 V, and capacity can be verified by timing a known-load discharge to reach roughly 19.2 Wh.

Does the box include a charger or only the 98.0 × 29.0 × 29.0 mm battery pack?

Only the single 282.0 g Ni-MH battery pack is included; a compatible charger must be purchased separately.
