1. battery is developed using the best materials and the latest LiPo cells available today This philosophy enables us to improve our products constantly by introducing new developments from other manufacturers For example the new charge IC made by chip manufacturer Texas Instruments was built into our products immediately it became available The charge system of the original battery was limited to max 10 5 Volts but only one year after the battery s introduction the new chip allowed us to increase the voltage spectrum for the charge system to 17 0 Volts This was particularly welcome because the new IC immediately made it possible to charge the battery from any 12 Volt car accessory socket As with our other PowerBox products these battery packs are assembled using what are known as gold circuit boards the surface of the conductor tracks is gold plated this allows components to be positioned more accurately and provides improved conductivity and resistance to oxidation The LiPo cells we use are manufactured specifically for our battery packs i e they are made to meet our precise specification for the purpose defined by us and are not just mass produced cells which were not originally intended for use in RC models Before any further work is carried out on them these cells are subjected to a sophisticated selection process here at PowerBox Systems matched to a tolerance of 1 1000 Volt and then assembled to form two cell packs Po2. charge process we recommend that you use our dedicated charging systems which have been developed specifically for the purpose Both charge units mains PSU and car adaptor have two contacts for simultaneous charging of two battery packs PowerBox Systems POWER BOX Battery 1500 2800 The integral electronic safety circuit which we build into every battery pack includes a temperature sensor and voltage time control system However this circuit is only active if you charge the pack using the mains PSU with 110 220 Volt input voltage for use world wide or the 12 Volt car adaptor The pack s internal LiPo balancers are also active if you wish or are obliged to charge it using a LiPo capable battery charger and the external charge lead Many modellers may want to check the charged in capacity or the consumption in mAh from time to time This can be carried out by charging or discharging the pack via the battery connecting lead using a LiPo capable battery charger but we do not recommend that you do this regularly As mentioned above no integral electronic safety circuits of any kind are active when you charge the pack through the battery connecting lead and it is then up to your battery charger to provide the safety measures By the same token you by pass the controlling mechanisms integrated into the charger so we can no longer guarantee correct charging of the pack Charging the PowerBox Battery is as simple as charging a mobile
