48V 20Ah Ebike Battery - Compatible With Bafang Conversion Kits & Rad Power Bikes

About This Product

Serious about e-bikes? This 48V 20Ah battery pack is built with quality that shows. Using genuine Samsung 5000mAh cells in a 13S4P configuration, you're getting honest capacity that delivers real range - no sketchy sand-filled packs or false capacity claims here. The built-in battery management system (BMS) provides comprehensive protection against over-charging, over-discharging, short circuits, and temperature issues. The individual cell holders are a nice touch - they prevent cells from touching each other, reducing fire hazards and improving heat dissipation. The security lock does double duty as both a power switch and anti-theft feature - twist the key to different positions to control different functions. It weighs in at about 4.74kg, which is the correct weight for this capacity (if it's lighter, that's a red flag). This battery works with most popular motor kits including Bafang and Voilamart, and it's specifically designed to fit some Rad Power Bike models like the Rad City and Rad Runner. Just note it doesn't work with Bosch, Shimano, Yamaha, or Panasonic systems. The manufacturer has over 10 years of battery experience since 2014, and their welding process is professional - no sloppy soldering or misplaced connections that can cause problems down the road. They even test these batteries through 1000 charge cycles and still maintain 78% capacity. If you need to return it, they offer 1-month return support (just message ZYNM2025@163.com). Whether you're building a new e-bike or replacing an aging battery, this pack delivers reliable power that'll get you where you need to go with plenty of range to spare. No more range anxiety on longer rides!
