This Mascot desktop charger has been specially developed for the high demands of modern lithium iron phosphate batteries (LiFePO4). With its 3-stage charging characteristic, tailored to LiFePO4 cells, it ensures safe, fast and cell-protecting full charging. The dedicated input voltage range of 198-264V makes this device an efficient solution for operation on stable 230V networks in Europe and industrial environments.Highlights at a glanceOptimised for LiFePO4: Special charging profile precisely matched to the voltage level and safety requirements of lithium iron phosphate batteries.Intelligent 3-stage charging: Process-controlled charging (CC-CV-Cutoff/Float) ensures full capacity without the risk of overcharging, which would be critical for lithium batteries.Efficient mains operation: Designed for an input voltage range of 198-264 VAC, ideal for dedicated 230V applications.High safety standards: Comprehensive protective circuits against short circuit, reverse polarity and overheating protect both the charger and the valuable battery.Robust construction: Designed as a desktop device, it provides a rugged housing for daily use in workshops, industry or medical technology.Status LED: The integrated LED indicator provides clear feedback on the current operating state (charging / finished / error).Gentle charging technology for lithium batteriesUnlike lead-acid batteries, LiFePO4 batteries require very precise shut-off. The Mascot charger uses a 3-stage process for this:Constant current (CC): The battery is quickly charged to approx. 90% with maximum current.Constant voltage (CV): The voltage is kept constant, while the current decreases, to fully saturate and balance the cells.End of charge / maintenance: After saturation the device switches off or changes to a safe monitoring mode to avoid stressing the battery with unnecessary float charging (model dependent).Reliability for professional applicationsMascot is known for durable power supply solutions. This LiFePO4 charger is excellently suited for mobile applications, electric vehicles, cleaning equipment or medical devices that rely on advanced lithium technology and require a reliable energy source. Features ModelMascot 2840 LiFePO4 (desktop charger) ApplicationCharger for lithium iron phosphate batteries (LiFePO4) Input voltage198 - 264 V AC (47-63 Hz) Charging voltageVariable depending on version (for 1 to 16 cells) Charging currentMax. 8.5 A (depending on voltage) Charging method3-stage (current detection as charge stop) Indicators3-colour LED (Red=Charging, Orange=End phase, Green=Finished) Protective functionsReverse polarity protection, short-circuit protection Dimensions (L x W x H in mm)135 x 80 x 44 Weight (kg)approx. 0.48  FAQs about the Mascot LiFePO4 desktop chargerCan I also use it to charge lead-acid batteries?No, this device is specially matched to the voltage characteristics of LiFePO4 cells. Charging lead-acid or other lithium chemistries (such as Li-Ion/LiPo) may result in incomplete charging or damage to the battery. Please use the relevant Mascot models for those applications.What does the input voltage range 198-264V mean?This range indicates that the charger is optimised for operation on power grids with a nominal voltage of 230V (as is common in Europe). It is not suitable for worldwide use in countries with 110V networks (e.g. USA), which often allows greater efficiency in the intended range.When is the battery fully charged?The battery is fully charged when the LED indicator turns green. The charger has then completed the constant voltage phase and has reduced or switched off the charging current to a minimum.Which plugs are compatible with the device?As with many Mascot desktop devices, the DC output is often designed flexibly (e.g. fixed cable or interchangeable plug system). Please check the specific product description for your model to ensure that the plug (e.g. XLR, hollow plug) matches your charging socket.
