52V 21Ah Triangle Ebike Battery — 50A BMS, UK Stock | LC Leccys

A compact 52V 21Ah triangle battery for 1500W–2000W builds. Smaller than a 30Ah pack, so it fits more frames while still giving strong performance.

Specs

• 52V 21Ah (1092Wh)
• 50A BMS: enough headroom for our 52V 2000W kits
• Charger included (58.8V output, UK plug)
• Triangle frame bag fit with velcro straps

Which kits does it suit?

Made for 52V systems: our 52V 2000W rear hub kit and the 52V complete kits. Not for 48V or 72V controllers.

Fit check

Measure the inside of your frame triangle, or send us a side-on photo of your bike and we'll confirm it fits before you order.

Charging tips

• Use the supplied 52V charger only
• Charge indoors on a hard surface, not overnight unattended
• Store at around 50–70% if the bike is parked up for weeks
