Frequently Asked Questions

• Can I charge four batteries at the same time with the X4 Mini? — Yes, absolutely. The X4 Mini features four completely independent output channels, each capable of operating with separate charge profiles. You can charge four different batteries simultaneously, using different chemistries, cell counts and amperage settings on each channel. This is one of the charger's primary advantages for users who operate multiple RC vehicles or maintain diverse battery collections.
• What's the difference between AC and DC input on this charger? — The AC input accepts standard 100-240V mains power from a UK wall socket, making it ideal for home or workshop use. The DC input option (19-26V) allows you to power the charger from portable external supplies at RC racing events, field locations or anywhere without access to mains electricity. When using DC input, each output channel can deliver its full 100W rating (providing the external supply can deliver sufficient amperage), but mains AC input shares a total of 100W across all four channels.
• Is the X4 Mini suitable for beginners to RC charging? — Yes, the X4 Mini is excellent for beginners due to its comprehensive support for all modern battery chemistries and its intuitive LCD menu system. The backlit display makes parameter selection straightforward in any lighting condition, and the ability to store up to ten battery profiles means you'll quickly build a library of pre-configured charging settings for your regular batteries. The built-in balance charging also protects valuable battery packs from damage caused by cell imbalances, which is particularly important for those new to RC who may not yet understand lithium battery management.
• What battery types does this charger support? — The X4 Mini supports LiPo, LiFe, LiIon, LiHV, NiMH, NiCd and lead-acid (Pb) chemistries. For lithium variants, it accommodates 1-4S cell counts. NiMH and NiCd batteries can be charged up to 8 cells, and lead-acid batteries from 2-14V.

• Can I use this charger if I don't have mains power available? — Yes, the X4 Mini can operate on DC input between 19-26V, which means you can power it from portable DC supplies, solar charging systems or vehicle power supplies at RC racing venues and field locations. This makes it genuinely portable and field-capable, unlike chargers limited to mains AC input only.
• How does the battery recall memory feature work? — The charger can store charging profiles for up to ten different batteries. After programming your preferred parameters for a particular battery (chemistry, cell count, charge rate etc.), you can save that configuration to the charger's memory. On subsequent charging sessions, you simply select the saved profile by battery number rather than re-entering all parameters, saving time and reducing the risk of input errors.
• What does the ±0.01V balance precision mean for my batteries? — Balance precision to within ±0.01V (one hundredth of a volt) is exceptionally tight tolerance and means that each cell within a lithium battery pack will be charged to virtually identical voltage levels. This is crucial for battery lifespan, performance consistency and safety, as unbalanced cells can fail prematurely or behave unpredictably during discharge, potentially damaging equipment or creating safety hazards.
