Bicycle battery Phylion

Phylion makes batteries for many brands, including bikes from Aldi, Lidl, Prophete and Puch. There are several models, such as Joycube SF-03, SF-06 and Wall-ES, Dolfijn and SilverFish. Look at the label on your current battery for the model and the type number, for example XH370-13J, and search for it in the search bar or the battery finder.

Then compare the position, the voltage and the plug with your current battery. Not sure? Send a photo of your battery and of the label via WhatsApp.

Yes. The new battery must have the same voltage as your current one, because your motor and charger are made for it. Phylion batteries come in 24 V, 36 V and 48 V. Some are listed as 36/37 V or 24/25.9 V: that's the same battery, just stated differently.

Within the same voltage you can often take a battery with more amp-hours. But check the dimensions: a battery with more capacity is usually bigger.

We sell both. Besides original Phylion batteries, we have compatible batteries for the Joycube SF-03 and Wall-ES, and batteries from Maratron.

A compatible battery is made for one particular model. The product page says what it's suitable for and whether a charger is included.

Usually just your current charger. If you buy a new one, check two things. The voltage: a 24 V battery is charged with a 29.4 V charger, a 36 V battery with 42 V and a 48 V battery with 54.6 V. And the plug: Phylion uses, among others, a 1-pin RCA plug, a 3-pin XLR plug, a round or trapezoid 5-pin plug and a round 5.5 × 2.1 mm plug.

Never use a charger just because the plug fits.

Is the item in stock, and do you order and pay before 14:00 on a working day? Then it leaves the same day. Orders that come in later or at the weekend are shipped on the next working day. You always see the shipping costs at checkout; see our Shipping and returns page for the rates.

You can't order an out-of-stock item straight away. On the product page, enter your email address and click "Keep me informed", adding a question if you like. We'll then let you know whether and when we can deliver it, and at what price.

You can return it within 30 days, even if you've already tried it. Returns from the Netherlands and Belgium are free; from other countries you pay the return shipping, unless we made a mistake. The item must be undamaged and come back in its original box. Email your order number to info@azparts.nl and within 1 working day you'll receive a return label (Netherlands and Belgium) or the instructions for your return. Our technicians check the item on arrival; after that we refund you.

Charge your battery at room temperature, between 10 and 25 °C, and never below 0 or above 45 °C. If you don't ride much, charge it at least once a month: a battery that runs completely flat can be damaged beyond repair. So never store it empty either, for example over the winter, and keep it out of strong sun and freezing cold.

Never put it in household waste: that's not allowed, and a damaged lithium-ion battery can cause a fire. Hand it in at your local recycling centre or at a bike shop that takes part in a battery collection scheme (in the Netherlands: Stibat).
