Frequently asked questions
These chargers fit the TranzX BL-520 36V:
. When you send us the battery, put your own charger in the box as well. We test them together.We do not offer a cell replacement for this type. That means one of two things: the cells cannot be taken out of this battery, or we have not seen enough of them yet to set a fixed price for a cell replacement. Repair is possible. The fault is then usually in the charging port or the electronics. Register the battery on this page, we run an intake test and send you a quote. We only start once you have agreed.
We know after the intake test, because the price depends on the part that has failed. You get a quote first. Expect more than €95. That amount is our inspection fee, and you only pay it if you turn down our proposal; we then send the battery back. If you accept, you pay for the repair and no inspection fee. If there is nothing we can do for your battery, it costs you nothing.
Register your battery on this page and follow the steps at checkout; we arrange the collection and send you the tracking details by email, with the time the courier will come. Put in the box: the printed insert form, the battery, the charger, and the key in a sealed envelope if your battery has a lock (do not tape it to the battery). Without the charger and the key we cannot test your battery fully. Your bike stays at home. Ask the courier for a proof of handover; that is your proof of shipping.
That depends on how busy the workshop is and on what we find in the intake test, so we do not quote a fixed number of days here. The current lead time is on our lead-time page.
Yes, on the work we carried out and on the parts we replaced. The warranty does not cover parts of the battery we did not work on. If we repair the charging port, for example, the cells are not included. The full terms are in our warranty conditions.

TranzX BL-520 36V carrier battery: repair
The BL-520 is a TranzX pack of 36V and 11 Ah that rides on the rear carrier. A common complaint is a battery that shows no lights at all after a winter in the shed, or one that stops halfway through charging.
Our workshop handles exactly these faults. We recover a pack that was drained too deep, put in a new BMS or circuit board where the old one has failed, and fix a worn charging port. Every BL-520 we receive gets its cells and BMS measured before we decide on anything. After that you get a proposal with the price, and nothing happens until you agree. If you decide against it, we send the BL-520 back for the inspection fee stated on this page.
For this TranzX model, Battery repair is the only option you can pick right now.
