FAQ:

Q1: How do I choose the correct discharge plug?
A: Check your ESC’s male connector.

• TRX: Standard on Traxxas vehicles.

• EC5: Common on Arrma, Losi, and upgraded racing ESCs.

• Deans T (T-Plug): Versatile, often found on older 1/10 models and DIY setups.
  If unsure, send a photo of your ESC connector to our support team for quick identification.

Q2: Over 6000mAh seems heavy. Will it ruin handling and jumps?
A: 566g is the perfect performance balance. Lighter batteries suffer voltage sag under heavy load, failing to unlock full motor power. This weight lowers the center of gravity on trucks and truggies, improving cornering stability and in-air control. For competition-tuned chassis, it is the ideal choice.

Q3: What if the battery dimensions are slightly too big?
A: Dimensions are 155x50x38.5mm (±3mm). Measure your battery tray carefully, especially the length. Many trays have removable or compressible foam pads that can accommodate a 152–155mm pack. Always do a dry-fit test before modifying any connectors. We support hassle-free returns if it won't fit.

Q4: Why only charge at 1C? Can't I fast charge?
A: Charging at 0.5C–1C (3.25A–6.5A) significantly extends the battery's peak lifespan. Slower, balanced charging ensures even chemical reactions, reduces lithium dendrite formation, and maintains low internal resistance and capacity over time. Rule of thumb: discharge at 100C on the track, charge gently at 1C at home.

Q5: Soft case battery — is it durable? Do I need extra protection?
A: Soft case optimizes weight and cooling but requires care. Protect against punctures, sharp edges, and severe impacts. Cover any exposed screws or carbon fiber edges in the battery tray. Inspect for swelling or damage after each run. Stored at 3.8V/cell, it will last hundreds of cycles.

Q6: There’s no manual. How do I use it correctly for the first time?
A: Follow three steps:

1. Inspect & Measure: Check for physical damage. All cells should read ~3.80V–3.85V (storage state).

2. Initial Charge: Perform a full balance charge at 1C (6.5A) to 4.2V per cell.

3. Gentle Activation: On the first run, drive slowly or gently rev the motor. A few mild discharge–recovery cycles activate the chemistry.
   After this, the battery is in peak racing condition.
