4. NG Avoid short circuits Short circuiting the battery results in very high currents which damage the inter nal structure of a LiPo battery This leads to a loss of power and capacity Never charge LiPo batteries without a balancer Charging without a balancer can damage the battery Please note that your limited warranty will void if you charge without balancer Be sure not to damage the outside of the LiPo battery The battery inside the hardcase is only protected by a heatshrink The actual Lipo cell is directly under this heatshrink If the outer skin of the cell gets damaged the battery can no longer be used Therefore take special care that no sharp objects like knifes tools carbon fibre edges or similar items can damage the hardcase and or the cells within it When securing the LiPo battery inside your model device you have to take care that the LiPo battery does not get damaged or warped in case of acrash LiPo batteries with a hardcase are less mechanical resistant then NiMH batteries in a metal can Therfore pay special attention that the LiPo battery does not get damaged or warped by letting it fall down hitting it bending it or by similar actions If you want to change the plug system of your LiPo battery take care that you only attach the new plugs to the power wires directly Under no circumstances your allowed to solder directly on the tabs of the LiPo cells Please note that there s the possibility to void your limited warr
5. anty when using a non reverse polarity protected plug system Never charge several LiPo battery packs at once with one charger The different capacities and charge levels can lead to serious overcharging of the battery even if you are using a charger with LiPo capabilities Damaged packs cannot be used any longer If the packs show signs of damage are bent or similar do not use the packs anymore The chemical reaction during charging and discharging a LiPo battery is not fully reversible Due to that LiPo batteries loose capacity during their life span This is normal and not a manufacturing nor production fault DISPOSAL NOTE Damaged packs or packs which can no longer be used are hazardous waste and have to be disposed accordingly Do not dispose the batteries in your household waste Completely discharge the batteries and hand them over to a designated collection point STORAGE LRP VTEC LiPo batteries do not have a memory effect and only a very low self discharge rate Therefore these batteries can be stored over a longer period of time without special treatment You only have to take care that the batteries do not get stored completely empty For a storage over a longer period of time we recommend to charge the battery up to 50 of the nominal capacity Therefore fully discharge the battery pack and then partially charge it with a charge current of 1C for 30 minutes In this condition the battery can be stored at least half a ye
6. ar at 25 C room temperature without the need of recharging it For a storage over a short period of time you also have to pay attention that the battery is partially char ged Never store the battery completely empty Even if you are using your battery regularly every week always pay attention that the battery is partially charged with at least 30 of the nominal capacity during storage A partial charge with 1C charge current for 20 minutes is sufficient in this case if the battery was competely empty before If you pay attention to the above mentioned notes you can enjoy your LRP VTEC LiPo battery for a very long time 6 INTERESTING FACTS ABOUT LIPO BATTERIES LiPo batteries shall only be charged at a temperature between 0 45 C If this will not be observed the cycle life of the battery will be reduced drastically The single cell open voltage of a fully charged LiPo battery is 4 2V The single cell open voltage of a 50 partial charged LiPo battery is approx 3 85V The single cell open voltage of an empty LiPo battery is approx 3 3V A voltage below 3 3V per cell without load is in either case harmful for a LiPo battery Therefore always avoid voltages below 3 3V per cell It is not visible from the outside when a LiPo battery gets overcharged The only way to find this out is to measure the voltage of the LiPo battery The battery does not heat up nor does it swell when it gets overcharged Therefore always check the battery v
