EVBike Battery 36V/13 Ah (470 Wh)

Check the photos of the new EVBike battery

Observe the polarity! Use the proper fuses!
The photo shows the EVBike Central controller after the customer installed the battery with opposite polarity without fusing.  Most DC powered products are very sensitive to the wrong polarity of the battery. Always check the proper polarity before installing the battery or turning on the main switch. 
Also always make sure there is a proper DC fuse between the battery and the controller. This will protect the controller or the battery against a sudden discharge in case of short circuit.
In the case of EVBike the controllers for the motors are tested in the factory before the assembly. Also after the assembly the whole kit is tested again to see the performance of the motor. In case of some internal problem on the controller board or the electronics this problem will be detected during the tests.  The significant burns of the controller board are cause by wrong polarity and using a battery with no fuse.
This damage of the controller is not a warranty case to be covered by the manufacturer.

EVBike with the central motor

Check the more detail for the EVBike Central Kit.

The new EVBIKE central motor system.

The EVBIKE kit with the central motor unit and the complete electrical equipment. The rated power is 250W @ 36V. Easy install in about two hours. Compatible with 99% bicycles.

Advantages:

- Lightweight and strong central power (peak 80 Nm)
- Quality and color code wiring connector with protection IP67
- LCD display showing battery status, data on the drive, with automatic backlight
- Four steps of power intensity depend on pedal assistance (0-3)
- All in one design - control unit, pedal assistent, engine is inside in one case.
- EBrake - brake lever sensor for safety ride
- For battery system 24 or 36 Volts

Proper connectors - the must to avoid problems in the future
The photo shows the EVBike connectors (at the motor side) that were burnt during a period of use. The reason of such a situation is the dirt on the terminals  and the improper connection. During high current peaks, the connectors overheat and the resistance of such connectors is increasing. The more the resistance is increasing, the more heat is emitted. As a result the connector may become burnt completely.
Make your connections proper. Keep your connectors clean.

EVBike with the central motor

We will be offering a new version of the EVBike kits in 2014. This version will feature the central assisting motor. Keep checking for the news at the EV-POWER.EU and the GWL/Blog.

Another EVBike “machine”
This EVBike is a prototype using the new central motor power assistant. The new central motor will be available in spring 2014.  We will give the updates at the GWL Blog, when this new product is ready for mass orders.

EV-BIKE battery connector

All EVBike kits are factory-equipped with 4-pin connectors, which are able to operate with high current from the EVBike lithium batteries. In case your connector is broken or if you are thinking of making your own strong EVbike battery from small LiFePo4 cells, you can buy spare MC12-4P connectors at EV-POWER.EU.

Examples of custom battery packs for hi-power EV-BIKE conversions:

Also do not forget to ckeck the proper polarity of the pins (plus and minus wiring).

Customer reference for nicely converted bikes to EVBikes!  Enjoy your ride!

How to improve performance of EVBike battery?
Did you know that both EVBAT36V7A and EVBAT36V10A batteries have integrated balancing circuit? If you keep your standard ev-bike charger connected over night (green LED ON), the charger will balance weaker cells up to the level of the strongest ones in the battery with a low current. If the performance of your battery is not as brand new, it is recommended to proceed balancing once per 10 rides. Balancing is also recommended when the battery was not used for several months, for example after winter. (Balancing of a brand new battery is not necessary and might actually shorten its lifetime.)
