LiFe RX Pack Guide: How to Choose a Receiver Battery
A LiFe RX pack powers your receiver and servos at 6.6V with no voltage regulator in the circuit. The 1500mAh pack at $11.99 suits small setups, and the 3300mAh pack at $34.99 suits larger planes and cars. All four packs in this guide are 2S 6.6V with JST-XH balance taps and up to 1000 charge cycles.
Quick facts
| Fact | Value |
|---|---|
| Voltage | 2S, 6.6V nominal, 3.6V per cell fully charged |
| Capacities | 1500mAh, 2200mAh, 2800mAh, 3300mAh |
| Discharge | 5C on 1500mAh, 25C on the other three packs |
| Cycle life | Up to 1000 cycles, per the listings |
| Balance taps | JST-XH on all four packs |

Why does a LiFe RX pack skip the regulator?
A 2S LiFe pack runs 6V receivers without a voltage regulator, per the listings.
Each cell reaches 3.6V fully charged, which gives a 2S pack its 6.6V nominal rating.
You plug the pack straight into the receiver, with no regulator to wire or fail.
How much capacity does your receiver need?
The 1500mAh pack weighs 92.8 g, while the 3300mAh pack weighs 179 g.
The 2200mAh pack measures 11.5 x 3.6 x 1.3 cm, and the 2800mAh pack measures 12.8 x 3.4 x 1.5 cm.
Pick the largest capacity that fits your battery bay and weight budget.
What does 5C vs 25C change?
The 5C pack delivers 7.5A, from 1.5Ah times a 5C discharge rating.
The 2200mAh 25C pack delivers 55A, from 2.2Ah times a 25C discharge rating.
Receiver and servo loads run far below those figures, so both ratings cover normal use.
How do you charge and balance a LiFe pack?
All four packs carry JST-XH balancing taps for balance charging.
The listings state fast charging, tolerance of full discharge, and up to 1000 cycles.
The 1500mAh pack adds a T connector for rapid charging alongside its 2 RX connectors.
What did we check against the listings?

We matched the 5C and 25C discharge ratings and the weights to their listings.
We counted 3 images on the 1500mAh listing and 2 images on each of the other three.
