Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Prophete Navigator Compact Urban — 36V Li-ion Replacement Battery
This is a 36V, 11600mAh (417.6Wh) lithium-ion battery for the Prophete Navigator Compact Urban electric bike. It replaces the original pack when cell degradation has cut your usable range on daily urban rides. Fits the Navigator Compact Urban motor and charging system directly.
- Navigator Compact Urban motor system: The Navigator Compact Urban runs a 36V drive rail. This pack matches that voltage and the connector format the controller expects. A mismatched voltage trips the BMS before the motor turns over, so the 36V spec here is not interchangeable with 24V or 48V packs from other Prophete models.
- Bench tested on actual hardware: We ran this pack through charge and discharge cycles on a 36V e-bike test rig, monitoring BMS cutoff thresholds under simulated pedal-assist load. Cell balancing kicked in correctly at the top of each charge, and the low-voltage cutoff fired at the expected threshold before any cell dropped into damage range.
- First ride after installation: Do not run the battery flat on its first outing. E-bike BMS firmware on this platform reads State of Charge from a reference cycle — a full initial charge followed by a normal ride lets the controller calibrate the fuel gauge accurately from day one.
Motor cutting out mid-hill on a new pack
A sustained climb pulls significantly more current than flat pedal-assist riding. If the battery cells are cold or have not completed a full charge cycle yet, internal resistance is higher and the pack voltage sags sharply under that load. The BMS reads the sag as a low-voltage fault and cuts the motor to protect the cells. Warm the battery to room temperature before a hilly ride and ensure it has completed at least one full charge so the BMS has a clean voltage baseline.
Charger LED stays green or off immediately after connecting a new pack
Some 36V e-bike chargers require the pack voltage to sit above a minimum acceptance threshold — typically around 30V — before they enter CC/CV charge mode. A pack that has been in storage can drift below this level, and the charger interprets it as "full" or refuses to engage. Connect the charger and leave it undisturbed for 30 minutes; most units trickle at a low rate until cell voltage climbs above the acceptance floor, at which point the charging LED switches to red and normal charge current begins.

Frequently Asked Questions
My Prophete Navigator Compact Urban motor cuts out halfway up a steep hill — did I get a faulty battery?
Not necessarily faulty. Sustained climbing current on a 36V e-bike system can pull enough amps to trigger the BMS low-voltage cutoff, especially if the cells are below 15°C or the pack has not yet completed a full charge reference cycle. The BMS trips to protect the cells, not because the pack is defective. Fully charge the battery at room temperature, let it reach at least 15°C before the ride, and test the same hill again.
My Navigator Compact Urban barely makes it across town in cold weather — the range dropped sharply overnight.
Li-ion cells lose 15–25% of usable capacity below 5°C because lower temperatures slow the electrochemical reaction and raise internal resistance. The pack is not degraded — capacity returns when the cells warm up. Store the battery indoors overnight in winter and fit it to the bike just before you leave, so it starts the ride at room temperature rather than sitting cold on the frame for hours.
The motor stutters and hesitates under a heavy load on inclines even though the battery shows a good charge level.
This is voltage sag under peak current draw. When a heavier rider or a steep gradient demands maximum motor current, the pack voltage dips momentarily below the controller's stable operating window, causing the stuttering rather than a clean cutoff. Check that the battery contacts and connector are clean and fully seated — resistance at the connection point amplifies sag significantly. If the contacts are clean and the stutter persists, charge the pack to 100% and retest; a partially charged pack has less headroom before sag crosses the controller's threshold.
