HRB Power Batteries 22.2 V (6S)

Overview

HRB Power 22.2 V (6S) LiPo batteries are built for high‑demand RC platforms that need strong, stable voltage under load. Nominal voltage is 22.2 V (3.7 V × 6); fully charged is 25.2 V (4.2 V × 6). These packs are commonly used in 1/7–1/5 scale cars, offshore boats, and heavy‑lift or long‑range multirotors that benefit from higher voltage and lower current for the same power.

When to Choose a 6S Pack

Use if

• Your ESC and motor are clearly rated for 6S (22.2–25.2 V).
• You want more power headroom with lower current (cooler wiring/ESC for the same output).
• Your model has room for a larger, heavier pack and can handle the added weight.

Avoid if

• Your electronics are limited to 4S or 5S—running 6S can cause failure.
• Weight or space is tight (small racing drones or 1/10 vehicles often suit 4S).
• You don’t have a charger that supports balance charging a 6S LiPo.

Common Specs and Fit Notes

HRB offers multiple 6S options. Always check the exact model’s dimensions, weight, C rating, and connector to ensure fit and compatibility.

Capacity (mAh)	Typical C Rating	Typical Connectors	Approx. Weight	Typical Use
4000–5200	50C–100C	XT90, EC5/IC5	600–900 g	Heavy‑lift drones, performance boats, 1/7 cars
5500–8000	50C–120C	XT90, EC5/IC5, AS150 (varies)	800–1200 g	1/5 cars, endurance boats, long‑range rigs

Connector adapters add resistance and heat—prefer matching connectors and adequate wire gauge (10–12 AWG for high current).

Runtime and Performance Planning

Estimated runtime (minutes) ≈ (Capacity in Ah ÷ Average current in A) × 60. Real‑world results vary with driving style, gearing/prop, and weather.

• Example: 5000 mAh (5 Ah) at 40 A ≈ 0.125 h ≈ 7.5 minutes.
• At 25 A average, the same pack ≈ 12 minutes; at 60 A ≈ 5 minutes.

Higher voltage lets you reach the same power at lower current (P = V × I), which can reduce heat and voltage sag. Re‑evaluate gearing or prop pitch when moving from 4S to 6S to keep motor temperatures in a safe range.

Pros and Cons of 6S

• Pros: Lower current for the same power, reduced heat in ESC/wires, stronger throttle response, stable voltage under load.
• Cons: Larger and heavier packs, higher cost, requires 6S‑rated electronics and a 6S‑capable charger.

Setup Checklist

• Confirm ESC and motor 6S rating; set low‑voltage cutoff to ~3.4–3.5 V per cell under load (≈20–21 V for 6S).
• Match connectors and ensure proper polarity; use suitable wire gauge (10–12 AWG for high current).
• Secure the pack with straps/foam; maintain center of gravity.
• For boats, protect from water ingress and allow ventilation for heat.

Charging and Storage

• Balance charge at 1C by default (e.g., 5000 mAh → 5 A). Only exceed 1C if the label/spec explicitly allows it.
• Use a balance charger set to LiPo 6S; verify the cell count before starting.
• Storage charge to 3.7–3.85 V per cell (≈22.2–23.1 V for 6S) for any break longer than a day.
• Charge and store in a LiPo‑safe bag or fire‑resistant container; never charge unattended.

Safety Limits

• Stop use if pack temperature exceeds ~60°C / 140°F or if you notice puffing or odor.
• Avoid discharging below ~3.3 V per cell at rest; plan to finish runs with some reserve.
• Inspect cells for damage and imbalance; cell deviation over ~0.03–0.05 V after rest may indicate issues.
• Do not mix old and new packs or different capacities/C‑ratings in series/parallel.

Alternatives

• Two 3S packs in series: Achieves 6S voltage with flexibility, but adds connectors and potential imbalance—monitor carefully.
• 4S: Lighter and common for smaller models; less power headroom compared with 6S.
• 8S: More power for very large models; requires electronics specifically rated for 8S and typically heavier packs.
• Li‑ion (6S): Better for long‑endurance, lower current applications; lower burst capability than LiPo.

FAQ

Will a 6S pack work in my 4S vehicle?

No. Using 6S on 4S‑rated electronics can permanently damage the ESC and motor. Always match the voltage rating.

What connectors do HRB 6S packs use?

Models vary; common options include XT90 and EC5/IC5. Avoid adapters when possible to minimize resistance and heat.

Can I charge HRB 6S packs at 2C?

Only if the specific pack label or manufacturer documentation allows it. If unsure, charge at 1C to preserve lifespan.

How should I store the battery long‑term?

Store at 3.7–3.85 V per cell in a cool, dry place (ideally 50–68°F / 10–20°C). Check voltage monthly and re‑storage‑charge if needed.

Can I run packs in parallel or series?

Only with identical cell count, capacity, age, and state of charge—and with proper wiring. Incorrect pairing can cause imbalance, heat, or failure.
