All the GWS Lithium-Polymer matched battery packs are matching the cells by capacity within ±2%, voltage with 3.75 ±0.02V and impedance with 40 mΩ±2 mΩ to ensure the battery deliver the highest performance, also with JST connector (gold plated contacts ) and silicone wire 20 AWG. These batteries can withstand 6C average discharge rate. |

Handling precautions and prohibitions for Lithium-Polymer batteries General information Lithium-Polymer ( abbreviation : LiPo) batteries require particularly careful handling. Mishandling these batteries may lead to explosions, fire, smoke and a risk of poisoning. Don’t series or parallel connect battery packs since the cell capacities and the charging condition may be too different. Therefore , battery packs we supply are selected. 1. Charging 1-1 Charging voltage : These batteries should charged with a charger that is specifically designed for LiPo cells, charging at above 4.25V per cell , which is the absolute maximum voltage. It must be strictly prohibited as higher voltage causes permanent damage to the cells and causes fires.
1-2 Charging current: The GWS LiPo batteries can be charged at a rate of max. 1.5C (1C corresponds to the cell capacity). Charging with higher current than recommended may cause damage to cell performance and safety features deeply, and can lead to heat generation or leakage.
1-3 Charging temperature: These batteries shall be charged within a range of temperature 0℃ to 50℃. If these batteries are charged at the temperature out of the specified range, leakage, heat generation or other damage may be caused.
1-4 Prohibition of reverse charging : Reverse charging is prohibited. These batteries shall be connected correctly. The polarity has to be confirmed before you make wiring.The reverse charging may cause damage to the cells which may lead to lose cell performance, and may damage to the cell safety which can lead to heat generation or leakage. 2. Discharging 2-1 Discharging current : The GWS LiPo batteries can be discharged at continuous currents as per what stated on each Lipoly pack (with 85~95% capacity).High discharging current may reduce the discharging capacity remarkably or cause overheats.
2-2 Discharging temperature : These batteries shall be discharged within a range of -10℃ to 60℃. At a temperature of -10℃ or less, the battery will show a significant decrease in discharge capacity. The battery temperature during the discharging should not exceed 70℃.
2-3 Over-discharging Normally, LiPo batteries start to discharge at 4.2V and terminate at a cut-off voltage of 3.0V. Discharging these batteries to a point below 2.5V per cell causes permanent damage to the cells, and this must be avoided. 3. Shipment For transport of lithium cells and batteries, the battery shall be shipped in 30% charged state for the safty reason. All GWS LiPo are charged in 30% charged state at the original manufacturer. Please refer to united-Nations UN3090.
