Gens Ace Lipo batteries are intended for use with radio controlled models only. R/C applications vary too greatly to cover every possible use in these instructions. The user must accept the duty to make smart and safe decisions about their desired application to avoid possible abuse and misuse. Non-R/C uses are not intended nor approved.
LiPo batteries can be damaged and CATCH FIRE if overcharged, shorted, damaged physically, or over-discharged
Over-charging, using an incompatible charger, or charging a battery that was previously damaged either physically or electrically can result in a catastrophic failure of the battery in the form of swelling, emission of smoke, and FIRE.
Over-discharging a LiPo (to a voltage lower than its rated minimum voltage) can damage a LiPo internally – even without the damage being visible in any way. Yet, a catastrophic failure (FIRE) could occur when attempting to re-charge the battery later.
LiPo failures are often a result of human error. Reading and understanding these instructions is CRUCIAL for avoiding problems, and to ensure personal safety and the protection of the surroundings.
CAPACITY: A way to rate a battery’s maximum energy storage limit, typically listed in “mAh” (milliamp-hours) and being the amount of energy the battery can deliver constantly over a period of one hour. Capacity rating is typically a way to gauge how much run time a 14.8 lipo battery can provide. The greater the rated capacity, the longer the run time.
C-RATING: A multiple of the battery’s capacity rating, calculated as the battery’s rated milliamp-hours (mAh) divided by 1000. C-ratings are used to establish various limits for a LiPo battery, such as a battery’s maximum charge and discharge current values. A battery rated at 2100mAh (1C = 2.1A) with a maximum charge rating of 3C could be charged at (2.1A x 3) 6.3 amps. A battery rated at 3200mAh with a maximum discharge rating of “25C” should be able to deliver(3.2A x 25) 80 amps of current during discharge.
SERIES PACK CONFIGURATIONS “S”: Electrically connecting multiple cells end-to-end places cells in “series”, with the resulting total pack voltage being the SUM of all cell voltages. Connecting packs in series is usually done to deliver more power (torque and/or speed) to the motor. A 3-series LiPo pack (3S) would have a total nominal voltage of (3 x 3.7V) 11.1V. A 4S pack has a total nominal pack voltage of (4 x 3.7V) 14.8V, etc. Connecting an 11.1V battery in serieswith a 7.4V battery will result in an overall voltage of 18.5V. Do not connect multiple packs together in series unless each has the same rated capacity (regardless of the rated voltage of each pack).
Gens Ace established in Year 1998 and mainly focus on mobile phone chargers and mobile phone batteries, Rechargeable batteries of Lithium Polymer (Li-po), Nickel Metal Hydride (Ni-MH) and LiFePO4 batteries, which used for various application, such as RC Models/Helicopter/Airplane/Boats/Cars, RC Toys and Power Tools, solar lighting, emerging lighting, cordless phone, walkie talkie, blue tooth, etc.
