The advantages of using a LiFe battery pack over the traditional NiCd/NiMH packs or LiPo packs are numerous. LiFe packs are a unique lithium battery chemistry that feature light weight and high energy density characteristic of lithium batteries, but are much more stable and do not require regulators to lower voltage.
Older JR transmitters operate at a higher voltage, therefore replacing the battery pack with the same battery in an XG-series radio is not possible. The 3F2100 is a 9.6v nominal pack that will operate the same in your transmitter as the original unit, but with much better performance and you’ll charge less frequently.
The charger and battery are available as a combo (JRPB4038) or individually as required.
