The Maclan Racing “Race Formula Graphene V3” battery is our latest 2020 chemistry. We continuously evolve the batteries with the latest technology to improve capacity/weight ratio (for better physical spec) along with lower IR (for better discharge performance). We also created all new ULCG (Ultra Low Center Gravity) super slim case options for both stick and shorty styles. Those will provide more competitive performance for extreme racers.  The Graphene V3 offers all the popular configurations, (stick and shorty) for both on and off road applications.

  • Better weight/ capacity ratio = Lighter weight with more power
  • Better discharge curves = Better voltage holding at the end of race
  • All new ULCG (Ultra Low Center Gravity) case options
  • 5mm bullet type connectors for maximum power throughput
  • 10C maximum charge rate, 3C charge rate recommended for the longest life span
  • 7.6V (2S) nominal voltage
  • ROAR approved


Introducing all new ULCG (Ultra Low Center Gravity) shorty pack at super slim 20mm thickness. The MCL6018 4500 mAh is the answer of for you. It is great for both 2WD and 4WD competition with ultra low CG and great discharge curve.

The MCL6017 was upgraded with more capacity to 6100 mAh while retaining the same weight.

The MCL6019 improves its capacity from 3600 to 4000 mAh with the same super slim 18.5mm package and same weight.

All shorty packs have remarkable improvement for 2020 racing program.




Introducing the all new ULCG (Ultra Low Center Gravity) stick style pack with super slim design, and only 19.5mm thickness. The MCL6016 5500 mAh pack is a great option for lower CG to favor racers at technical and compact on road layout.

The MCL6015 8500 mAh receives upgrading formula to reduce its weight for 6g while retaining the same capacity and improving its IR for better discharge curve for stock class competition.

The MCL6020 6800 mAh retains its LCG design at 22.5mm thickness. However, it improved the capacity from 6400 mAh to 6800 mAh without increasing its weight.

Charging & Discharging

  • DO NOT charge the battery on a wooden workbench or on any flammable material.
  • DO NOT leave the battery in your model when charging.
  • DO NOT charge the battery inside a motor vehicle, or in a vehicle’s engine compartment.
  • DO NOT leave unattended when charging.
  • NEVER allow the battery voltage to drop below 3.0V per cell.
  • ALWAYS charge the battery with a Li-Po charging bag .
  • ALWAYS balance charge the battery at or below the specified charging rate.
  • ALWAYS discharge the battery to its 30% of capacity in storage.
  • Only charge Li-Po batteries with a charger designed specifically for charging Li-Poly batteries. Using other types of chargers may cause explosion or fire.
  • Maclan Racing ships the batteries with a 30% charge. The initial charging time of the battery will be shorter when compared to a fully discharged battery pack.
  • Li-Po batteries do not have a memory effect like NiMH and NiCD batteries. You do not need to fully discharge the battery completely before you recharge it

Care & Handling

  • NEVER short the Li-Po battery connectors! Handle all Li-Po batteries with care. Li-Po batteries can deliver extremely high currents if shorted and subsequently can cause fire or injury
  • Always store Li-Poly batteries in a secure fireproof location where children cannot reach them.
  • Store your batteries in a cool, dry place. Do not leave your battery exposed to direct sunlight or temperatures below 32 degrees Fahrenheit (0 degrees Celsius), or above 122 degrees Fahrenheit (50 degrees Celsius).
  • NEVER overcharge or overdischarge your battery.

Disposal Note

The Lithium-ion batteries do not contain toxic metal elements. Rather, they contain recyclable materials and are recommended to be disposed under recycling program. Dispose in accordance with applicable regulations which vary from country to country. Batteries should be completely discharged and/or the terminals taped or capped to prevent short-circuit. When completely discharged, it is not considered hazardous. Disposal of large quantities of Lithium-ion polymer batteries or cells may be subject to the local regulations concerned.
