Overview
Two capacities for the L20 3.0 Boost. The 13.5 Ah pack uses 21700 cells with an advanced BMS chip and is compliant with EN 50604, the European standard for e-bike batteries. The 15 Ah pack steps up to Samsung 21700 cells for more range again.
Why riders choose the L20 3.0 Boost Battery
- EN 50604 compliant. The European safety standard for light electric vehicle batteries — worth checking for on any replacement pack.
- Samsung cells in the 15 Ah version. A named cell manufacturer rather than an unattributed one.
- 8A fast charging — full in about two hours on either capacity.
- Advanced BMS chip for intelligent charge and discharge protection.
L20 3.0 Boost Battery in detail
13.5 Ah or 15 Ah?
The 15 Ah pack holds roughly 11% more energy for about €100 more. If you regularly finish rides near empty, take the larger one. If you are replacing a failed pack and your range was adequate, the 13.5 Ah is the like-for-like choice.
Why EN 50604 matters
It is the standard that covers electrical safety, thermal behaviour and mechanical robustness for e-bike batteries. Unbranded replacement packs frequently do not meet it.
Who it suits
- L20 3.0 Boost owners replacing a pack or adding a spare

Road legality and safety
Lithium-ion batteries are safe when treated properly and dangerous when they are not. Charge indoors, on a hard non-flammable surface, within sight, and unplug when full. Do not charge a pack that is damaged, swollen or has been submerged. Use only the charger supplied for this pack. At end of life the battery must be recycled through a battery collection point, not put in household waste.
