CNHL Lightning LiHV 8500mAh 15.2V 4S 120C HV LiPo Battery with QS8 Plug

Quick Fit Check

The CNHL Lightning LiHV 8500mAh 15.2V 4S 120C HV LiPo Battery with QS8 Plug is a high-capacity, high-current battery for powerful RC boats, aircraft and custom electric systems where a QS8 connector and 8AWG wiring are appropriate.

At approximately 149 × 50× 44mm (L × W × H) and 679g, this pack combines 8500mAh of rated capacity with a 120C continuous discharge rating for applications where energy reserve and high-current delivery matter more than minimum battery weight.

Because this is a 4S LiHV battery, a full charge reaches 17.4V. Confirm that the ESC supports the selected maximum voltage before charging above the standard 16.8V 4S LiPo limit.

Product Specifications

8500mAh Capacity for High-Power 4S Systems

The CNHL Lightning 8500mAh 4S LiHV prioritizes energy reserve and high-current capability. Its 8500mAh capacity makes it particularly relevant where longer operating time is useful and the platform can comfortably carry an approximately 679g battery.

Unlike smaller lightweight 4S packs, this battery is intended for systems where high capacity, QS8 connectivity and heavy-gauge wiring are more important than minimizing battery mass.

Why QS8 and 8AWG Matter

The QS8 connector and 8AWG wiring are key parts of this battery's positioning. This combination is aimed at high-current RC power systems rather than general low- or medium-power 4S applications.

If your model uses XT60, XT90, EC5, IC5 or another connector, do not select this battery simply because the voltage and dimensions fit. The complete connector path, polarity, current rating and wiring arrangement must also be appropriate.

Why Choose This Battery?

• 8500mAh capacity: High energy reserve for longer high-power sessions.
• 120C continuous rating: Designed for demanding electric power systems.
• QS8 connector: High-current connection suited to powerful RC installations.
• 8AWG wiring: Heavy-gauge output wiring for demanding current loads.
• 149mm length: Compact relative to its high capacity.
• LiHV chemistry: Supports up to 17.4V full charge when the electronics are rated for it.

4S LiHV Power for Large RC Aircraft

This battery can also be considered for large RC airplanes and other electric aircraft designed around high-capacity 4S power, especially when QS8 and heavy-gauge wiring suit the installed power system.

Always verify battery bay dimensions, installed weight, center of gravity and full LiHV voltage support before flight.

Matched Dual-4S Battery Use in 8S Systems

Two identical 4S 8500mAh packs may be connected in series for a compatible 8S 8500mAh system. Series wiring doubles voltage while capacity remains 8500mAh.

Two fully charged LiHV packs can reach 34.8V in series, so the complete ESC and electrical system must support that maximum voltage.

LiHV Charging and Maximum Voltage

This is a 4S LiHV battery. A full LiHV charge reaches 4.35V per cell, or 17.4V total.

A standard 4S LiPo reaches 4.20V per cell, or 16.8V total. Do not assume that every ESC described as 4S-compatible supports the higher 17.4V LiHV maximum.

If full LiHV support has not been confirmed, this battery can be balance charged to the standard LiPo limit of 16.8V / 4.20V per cell.

For routine charging, a balanced 1C rate is preferred. 5C is the stated maximum, not the everyday target.

FAQ

What makes this battery different from a typical 4S pack?

Its main distinctions are the 8500mAh capacity, QS8 connector, 8AWG wiring and 120C stated discharge rating, which position it toward high-current applications rather than general-purpose 4S use.

Can two batteries be used for 8S?

Yes, when the complete power system is designed for series operation. Two matching 4S packs in series create an 8S 8500mAh system.

What is the maximum voltage of two packs in series?

Two fully charged 4S LiHV batteries can reach 34.8V in series.

Can I charge this battery only to 16.8V?

Yes. A LiHV battery can be balance charged to the standard 4S LiPo limit of 16.8V when full 17.4V LiHV voltage is not required or has not been confirmed for the electronics.

Should this battery always be charged at 5C?

No. For routine charging, a balanced 1C rate is preferred. 5C is the stated maximum, not the everyday target.

Notice

• This is a 4S LiHV battery with a maximum charge voltage of 4.35V per cell.
• If full LiHV support has not been confirmed, charge only to the standard 16.8V / 4.20V-per-cell LiPo limit.
• Confirm the 149 × 50.15 × 43.7mm dimensions, approximately 679g weight and QS8 connector before use.
• QS8 is a high-current connector; do not assume direct compatibility with XT60, XT90, EC5, IC5 or other connector systems.
• Voltage and connector alone do not establish compatibility; battery dimensions, weight, retention, cooling and electrical requirements must also match.
• For series operation, use matching batteries of similar age, condition and state of charge.
• Two fully charged 4S LiHV packs can reach 34.8V in an 8S series configuration.
• Secure the battery firmly and keep power and balance leads clear of propellers, shafts, couplers, gears and sharp edges.
• Never charge unattended, and do not use a swollen, punctured, damaged or overheated battery.
• Allow the battery to cool before recharging and use storage mode when it will not be used for an extended period.
