HRB Power Batteries

HRB Power Batteries: Practical LiPo Packs for Everyday RC Use

HRB Power Batteries provide dependable LiPo performance at a budget-friendly price. They come in popular voltages (2S–6S), capacities, and connectors, covering RC cars, boats, planes, and FPV drones. These packs are a strong fit for bashing, practice days, club racing, and multi-model fleets where value and consistency matter.

When to Choose HRB

• Use if: You want reliable power for bashing, practice, or casual racing; you need multiple packs without overspending; you prefer common connectors and honest labeling.
• Avoid if: You compete at the highest level and need the lightest packs with minimal voltage sag; you routinely pull extreme current spikes above ~150A from a single pack.

Common Specs & Compatibility

• Voltages: 2S–6S (7.4–22.2V nominal)
• Capacities: Typically 1300–6000 mAh (e.g., 1300–1800 mAh for 5" FPV; 4000–6000 mAh for 1/8 cars and larger aircraft)
• C ratings: Commonly 50C–100C; choose based on your model’s current draw (see guidance below)
• Connectors: Often XT60, XT90, EC5/IC5, and Deans T-plug; balance leads use JST-XH (standard on most chargers)
• Wiring: 10–12 AWG on higher-current packs; avoid thin adapters that add resistance

How to Choose the Right HRB Pack

1. Match voltage (S count): Follow ESC/motor specs. Cars and boats: 2S–6S depending on scale. 5" FPV: 4S or 6S.
2. Pick capacity: More mAh = longer runtime but higher weight. Balance flight/handling or vehicle temps.
3. Set C rating: Estimate peak current and add headroom (30–50%). Example: 80A peak draw → choose ≥100A continuous capability; a 5000 mAh 50C pack (250A theoretical) is ample.
4. Check connector and space: Match your ESC plug and confirm pack dimensions fit the tray or strap area.

Quick Recommendations

Expected Runtime Examples

• 1/10 basher (3S 5000 mAh): 15–30A average → about 10–18 minutes; heavy throttle reduces time.
• 1/8 truggy (6S 5000 mAh): 25–45A average → about 7–12 minutes.
• 5" FPV (6S 1300 mAh): 15–25A average → about 3–5 minutes (freestyle); cruising extends to 6–7 minutes.

Charging, Storage, and Care

• Charge rate: 1C is the safe default (e.g., 5A for 5000 mAh). Only exceed if the label explicitly allows it.
• Balance charge only: Use LiPo balance mode every cycle for even cell voltages.
• Storage voltage: 3.75–3.85V per cell; store cool and dry.
• Cutoff: Stop around 3.5V per cell resting; under load, avoid dropping below ~3.3V per cell.
• Temperature: Keep packs under ~60°C/140°F. Let cool to ambient before recharging.
• Inspection: Do not use packs that are puffed, damaged, or have torn insulation. Dispose at a battery recycler.

Performance Notes

• Voltage sag: HRB packs hold up well for general use; at extreme bursts (>150A), expect more sag than ultra-premium, race-weight packs.
• Weight: Often a bit heavier than top-tier race packs. Example: a typical 6S 5000 mAh LiPo weighs ~780–820 g; check the specific listing.
• Internal resistance (IR): Look for consistent IR across cells; larger car packs often show ~1–3 mΩ/cell when new, while 1300 mAh FPV packs might show ~8–15 mΩ/cell.

Series/Parallel Use

• Only combine packs that are the same capacity, C rating, age, and state of charge.
• Use matched connectors and short, thick leads; mismatched or long adapters add heat and voltage drop.

Pros and Cons

• Pros: Strong value, broad size/connector coverage, consistent labeling, reliable day-to-day performance.
• Cons: Slightly heavier than elite race packs; more sag at extreme current; availability of specific dimensions can vary.
