The WR-TEAM 48 V 20 Ah battery is aimed at riders who have built or bought a conversion kit e-bike and want as much range as possible from a single pack. It has the largest capacity in our guide and names its cell supplier, Samsung, which few aftermarket listings do. It is a pack for tinkerers rather than a direct swap for a specific factory bike.

- Samsung 50GB cells are named, plus a 30 A BMS and 3 A charger.

Our take
Capacity and cells
The title lists 48 V and 20 Ah, built from Samsung 50GB cells described as 5000 mAh A+ grade. At 48 V that is around 960 watt hours, a large reserve for long commutes. The specification table contradicts this with a 1300 mAh capacity field, which looks like an error, so confirm the version with the seller.
A 30 A BMS protects against over-charge, over-discharge, overcurrent and short circuits, and the pack is said to suit 250 W motors with 17 A to 30 A controllers.
Features beyond the cells
WR-TEAM includes a USB port for charging a phone or speaker, a power switch to stop slow drain, a lock against theft and an LED power indicator. The discharge connector is Anderson, and a spare cable is offered.
The charger is 54.6 V at 3 A, quicker than the 2 A units supplied with most packs in our guide.
Size, mount and warranty
Dimensions are 36.5 by 9 by 12.7 cm and the battery weight is given as 5 kg. The model number begins HL, which hints at a Hailong-style case, but the listing never states the mount, so check rail type and lock position against your frame.
The one-year warranty is unusually detailed. The seller says opening the case does not void it, offers free return or replacement within three months, and after that will try to repair a faulty BMS or switch before sending a new pack. No certification marks are listed.
Who it does not suit
Riders with factory e-bikes from brands such as Bosch, Shimano or Yamaha systems should not consider it. If you want a stated UKCA mark, the FEIMOKY HL-4813UK is the 48 V alternative, though with 13 Ah rather than 20 Ah. If your bike runs at 36 V, look at the X-go Hailong instead.
Verdict
Pick the WR-TEAM if you run a 48 V conversion kit with an Anderson connection and want maximum range and a faster charger. If certification matters more than capacity, choose the FEIMOKY HL-4813UK, and 36 V kit owners should look at the X-go Hailong.
