Product Overview
The CNHL Lightning LiHV 4000mAh 4S 120C LiPo Battery with XT90 Plug is built for RC pilots who want strong throttle response and stable voltage without stepping up to a heavier high-capacity pack.
Because this battery uses LiHV chemistry, it can be charged to a higher voltage than standard LiPo packs. In practice this usually gives a slightly stronger initial throttle feel and more energetic takeoffs.
With a 120C discharge rating, the pack is capable of supporting demanding aircraft setups where quick throttle changes and consistent power delivery matter.
Typical Applications
- 1.2m – 1.5m RC airplanes
- Sport and scale warbirds
- Medium-size EDF jets
- FPV fixed-wing platforms
Compatible RC Models
This battery is commonly used in RC aircraft that require a reliable 4S power setup, including models such as:
- FMS 1400mm T-28 Trojan
- AtomRC Swordfish
- Eflite SNJ-5 / AT-6 Texan 1.5m

FAQ
What is the advantage of LiHV batteries?
LiHV batteries can be charged to a slightly higher voltage than standard LiPo batteries, which typically results in stronger throttle response and slightly improved early-pack performance.
Is 4000mAh a good capacity for a 4S RC airplane?
Yes. A 4000mAh 4S battery is often considered a practical middle-ground size that provides good flight time while keeping overall aircraft weight manageable.
What connector does this battery use?
This battery uses an XT90 connector, commonly found on higher-power RC setups that require greater current capacity.
Notice
- Ensure both voltage and connector type match your RC model before use.
- This is a LiHV battery. Stop charging when the cell voltage reaches 4.35V per cell.
- Check the battery surface and voltage before first use.
- If the battery does not hold a full charge initially, cycle it several times using a balance charger.
