B4-800D Balance Charger for Gel Blaster Batteries 7.4V & 11.1V LiPo Charging with Digital Voltage Display Keep a closer eye on your gel blaster battery with the B4-800D. Designed for compatible multi-cell lithium batteries, it combines balance charging with a digital display that cycles through individual cell voltages and the total pack voltage. Whether you use a compatible 7.4V (2S) or 11.1V (3S) LiPo battery, the B4 helps you see how evenly its cells are charged. Why Choose the B4? Individual Cell Voltage Display: View each cell’s voltage and spot differences that a total-voltage reading alone cannot reveal. Balance Charging: Helps bring healthy cells toward similar voltages at the end of charging. Total Pack Voltage Readout: Check the battery’s overall voltage alongside its individual cell readings. For Compatible Gel Blaster Batteries: Supports common 7.4V and 11.1V LiPo packs with the appropriate balance connector and charging requirements. Flexible Power Options: Use the matching wall adapter or the DC input cable with a compatible external power source. Why Cell Balance Matters An 11.1V LiPo battery contains three cells. If those cells become unevenly charged, one may reach its discharge limit sooner, reducing usable runtime. Balance charging helps manage voltage differences, while the B4’s display makes those differences easier to notice. Power Options for Home and Outdoor Use Plug Adapter Required: The supplied power adapter has a Chinese-standard plug. If it does not fit your local outlet, you will need to provide a suitable plug adapter (not included). Check that the power adapter’s input voltage rating matches your local mains supply. Check Compatibility Before Use Confirm your battery’s chemistry, cell count, balance connector and permitted charge rate match the charger’s specifications. Voltage alone does not guarantee compatibility. Use only undamaged batteries and never leave charging unattended. Balance charging cannot repair swollen, damaged or severely over-discharged cells. See every cell. Make balance charging part of your gel blaster battery-care routine.
