3. 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 NOSRAM VTEC X treme Race 65C Hardcase Lipo batteries for a very long time 6 INTERESTING FACTS ABOUT LIPO BATTERIES e 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 e 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 e 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 e t 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 voltage during charging If it exceeds the max charging voltage stop the charging process immediately and check all settings e We recommend to stop discharging a Lipo battery if the remaining capacity reaches 30 of the nominal capacity With
4. arge levels can lead to serious overcharging of the battery even if you are using a charger with LiPo capabilities e Damaged packs cannot be used any longer If the packs show signs of damage are bent or similar do not use the packs anymore e 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 NOSRAM VTEC X treme Race 65C Hardcase 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 char ge current of 1C for 30 minutes In this condition the battery can be stored at least half a year at 20 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 charged Never store the battery completely empty Even if you are using your battery regularly every week
5. efore you can also charge batteries with a partial charge in them without the need of discharging the pack before Partially charged packs can be stored over a long period of time without getting damaged Please also see the Storage section for further reference Cell configuration C Nominal capacity of the battery E g with a nominal capacity of 5300mAh 5 3Ah the battery can be charged with a max current of 15 9A All NOSRAM VTEC X treme Race 65C Hardcase Lipo batteries are capable of a maximum peak discharge current of 100C The special manufacturing technology of the NOSRAM VTEC X treme Race 65C Hardcase Lipo batteries make these high discharge currents possible Please note Always take care that the battery gets enough cooling when discharging it with high discharge currents You have to take care that the batteries do not get deep discharged As soon as the hattery vol tage falls below 3 00V per single cell the battery pack gets damaged irrevocably With 2S packs as the NOSRAM VTEC X treme Race 65C Hardcase Lipo batteries the discharge cut off voltage under load is 6 0V With 1S packs the discharge cut off voltage under load is 3 0V The battery voltage should never fall below these discharge cut off voltages If your speed control does not have a special undervoltage protection for LiPo batteries you have to stop your model early enough in order not to deep discharge the battery pack Therefore stop immediately as s

7. ngle cell is mandatory during the charge of LiPo batteries ATTENTION Never charge your LiPo battery without a balancer directly connected to the balancing port of your battery unless your charger is already equipped with a balancer The maximum charging voltage for each single LiPo cell is 4 20V If the battery reaches this voltage the charge current has to be lowered This is automatically done by the charger If the charge current reaches 0 05 0 1C the battery is fully charged All NOSRAM VTEC X treme Race 650 Hardcase Lipo batteries consist of multiple LiPo cells You can see the max charging voltage in the table below We advise the following settings for charging our NOSRAM VTEC X treme Race 65C Hardcase Lipo batteries max max charge current charging voltage NOSRAM VTEC X treme Race 65C 1S 3 7V 4 20V NOSRAM VTEC X treme Race 65C 2S 7 4V 8 40V NOSRAM recommends these charge settings for optimum performance Cell configuration recommended max charge current charging voltage NOSRAM VTEC X treme Race 65C 18 3 7V 4 20V NOSRAM VTEC X treme Race 65C 2S 7 4V 8 40V Please Note You can use your NOSRAM VTEC X treme Race 65C Hardcase Lipo battery several times a day However be sure that the battery has completely cooled down to ambient temperature before re charging it again NOSRAM VTEC X treme Race 65C Hardcase Lipo batteries do not have a memory effect and only a very low self discharge rate Ther
8. oon as you feel a rapid loss in power IMPORTANT The max temperature of the LiPo battery during discharge must never exceed 65 C 150 F 4 SPECIAL NOTES FOR HANGLING e Avoid short circuits Short circuiting the battery results in very high currents which damage the internal structure of a LiPo battery This leads to a loss of power and capacity e 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 e 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 e 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 a crash 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 e Never charge several LiPo battery packs at once with one charger The different capacities and ch
