Cell Brands
The 36V platform is the optimal choice for city, commuter, and folding ebikes where weight, cost, and portability matter most. At 2.0–3.2 kg finished weight (36V 10Ah), these packs are engineered for riders who prioritize daily usability and low cost of ownership over maximum power output.
Our 36V BMS lineup is specifically calibrated for 10S cell configurations with active cell balancing, ultra-low self-discharge mode for seasonal storage (under 3% per month), and a configurable deep-sleep mode compatible with most display systems. The standard charge profile accepts 42V input, we supply matching 2A and 4A wall chargers with EU/UK/US/AU plug options and custom branding available.
For OEM buyers entering the European city-bike segment, this product ships with CE marking (LVD + EMC), UN38.3 transport certification, and RoHS compliance, all backed by our documented quality control process. All documentation is in English with German translations available for distributors selling through German-language markets.

Frequently Asked Questions
What is the difference between 36V and 48V for ebikes?
36V is lighter, costs less, and works well for city speeds up to 25 km/h. 48V delivers more power for hilly terrain, cargo, or higher top-speed markets. We can build both and help you choose based on motor rating.
Can you supply matching 36V chargers?
Yes. We supply 42V 2A and 42V 4A chargers to match. Custom wall plug (EU/UK/US/AU) and custom branding on the charger housing is available.
Are 36V batteries CE certified for EU market?
Yes. Our standard 36V packs include CE (LVD Directive 2014/35/EU + EMC Directive 2014/30/EU) and UN38.3 transport testing. IEC62133-2 available on request.
