Frequently Asked Questions

• Is the Gens Ace G-Tech 8000mAh suitable for my Losi Promoto? — Yes, this battery is specifically designed for Promoto compatibility. The 2S 7.4V configuration matches Promoto's electrical system requirements perfectly. However, it is essential that you charge this battery to standard LiPo voltage only (7.4V nominal) and do not charge it to HV (High Voltage) LiPo specifications, as the Promoto's electrical components are not rated for HV LiPo operation.
• What does the 60C discharge rating mean? — The 60C rating indicates the maximum continuous discharge current in amps, calculated by multiplying the capacity by the C rating. For an 8000mAh (8Ah) battery, 60C equals 480 amps of maximum continuous discharge capability. This ensures the battery can deliver sufficient power for responsive acceleration and sustained performance without excessive voltage sag.
• How long will this battery last on a single charge? — Runtime depends entirely on your RC model's power consumption, driving style and motor specifications. Generally, larger capacity batteries like this 8000mAh pack will provide extended run times compared to smaller batteries, often allowing 20-30 minutes of mixed driving on a single charge in typical RC car applications.
• What is the difference between this hard-case battery and soft-pack LiPo batteries? — Hard-case batteries feature a rigid polymer external casing that protects the delicate lithium polymer cells from physical damage, impacts and abrasion. Soft-pack batteries use only a thin foil envelope, offering lighter weight but providing minimal mechanical protection. For RC applications where durability and longevity are priorities, hard-case construction provides superior protection and longer operational life.
• Is this battery waterproof? — No, like all lithium polymer batteries, this pack should be protected from water exposure and moisture. The electronics and cells can be damaged by water contact, so keep the battery dry and store it in a moisture-controlled environment.
• What charger do I need for this EC5 battery? — You will need a LiPo-compatible charger that supports 2S battery charging and features an EC5 connector or an appropriate connector adapter. Many modern RC chargers include EC5 compatibility or provide adapter cables for alternative connectors.
• How should I store this battery? — Store the battery in a cool, dry location away from direct sunlight and heat sources. Ideally, maintain storage temperature between 10-25°C and store the battery at approximately 50% state of charge. Check periodically that the battery has not swollen or shown signs of damage.
• Is the Gens Ace G-Tech suitable for beginners in the UK RC hobby? — Yes, this battery is suitable for both beginner and experienced RC enthusiasts. The hard-case construction makes it more forgiving during transport and use compared to soft-pack alternatives, making it an excellent choice for newcomers learning to maintain and care for RC batteries.
