The bikeboard batteries

Basics

The batteries used on the E-Bikeboard, are a Lithium Polymer type. These batteries are designed using the latest technology for high power density, low weight and for long life. Before using the E-Bikeboard for the first time, please charge both Batteries until the green LED on the charger unit lights up (approximately 4.5 hours). After charging the batteries, check its capacity with its local operator interface by pressing the ”ON”- button of the tester. The display is located on the top of the battery when it is properly attached to the E-Bikeboard. The digital capacity indication shows 100% load when the battery is fully charged and 0% when the battery is completely discharged. 9.2 Battery operator interface The LCD display of the local battery operator interface has 5 different performance data indications which it displays sequentially by repeatedly pressing the ”ON”- button located next to the display. Each of the 5 different displays shows a bar graph on the top and a percentage value in the middle. Both indicate the remaining battery capacity, starting from a value of min. 10’000mAh and declining. On the last line of the display, you’ll see the following performance data upon pressing the ”ON”-button (each push of the button activates the backlight of the display for 5 seconds and afterwards the light disappears. The same indication remains still easily readable in daylight):

battery indication

1 x ON: Battery-Capacity-indication in mAh	2 x ON: Calculated, remaining ride time in min.; after charging, an irrelevant theoretical high value is displayed	3 x ON: Actual voltage of the battery in Volts
4 x ON: Actual current in amps: neg. prefix = operating current; no prefix = charging current	5 x ON: Number of load cycles the battery has accumulated already	6 x ON: Display off. One more push on the button restarts with capacity indication

The battery in its operation

The digital battery operator interface on the top of the battery shows the approximate remaining battery capacity at any time, as well as more actual performance data (as explained above) when pressing the test button. Never check the battery while you are riding, you must be at a complete stop when doing so.

Charging of the batteries:

To charge the battery, it is preferable to take them off the E-Bikeboard first: Turn battery key lock into position “UNLOCKED”. The key lock should turn easily. Should this not be the case, verify the position of the battery, it has possibly moved slightly during riding which causes some pressure on the key lock. If this is this case, try to push or pull the battery into a position in which the key lock turns easily. You can now fold up the handle and pull the battery by its handle out of the rails. You may prefer to charge the battery directly on the vehicle. If you do so, you must first switch off the battery with its red toggle switch; see section 7 “From the smallest transport dimension into ready for use” for further instructions before you proceed the same way you would have if you had pulled them out. First open the protection cap of the charging socket at the battery. Then connect the battery plug of the charger into the battery charging socket and the charger’s power cable into a standard socket-outlet (110 ... 240Vac / 50 or 60Hz). Charge the battery until the charger’s status LED turns from red to green. This may take 4.5 hours. After both batteries are fully charged, verify their status on the local operator interface by pushing the test button on the top of the battery. With full capacity, the digital display shows 100% charge and min. 10’000mAh and the maximum voltage is then approx. 29.4V (a new battery may already indicate 100% capacity and max. mAh at a lower voltage due to the additional capacity it has at the beginning). ALWAYS CHARGE BOTH BATTERIES TOGETHER AND USE ONLY AN ORIGINAL BIKEBOARD CHARGER. At the end of battery charging, you need to once again cover up the charging socket with the black protection cap. This is important as there is always full battery voltage on the pins of the charging socket. The protection cap prevents accidental short circuiting on the pins and keeps the charging socket clean.

The protection caps of the charging socket and the mini-USB socket must be closed at all times .

Caution:

Do not combine batteries with different charge levels on the same EBikeboard. i.e. one fully charged battery with one partially discharged battery. This harms the battery and reduces its lifetime. When you have more than one EBikeboard in use, make sure not to mix battery packs. The two batteries belonging to one set are marked with the same set-number on the top of the cover, together with the letters ”L” for left ”R” for right (i.e. L455 and R455); those two batteries must always be used together.

Safety instructions

Follow all safety instructions regarding the handling of the batteries, including the following: • Only charge with approved, original Bikeboard battery charger.
• Use only within temperature range of -20°C (-4F) and 60°C (140F). Do not expose batteries to high heat.
• Do not let children play with the battery.
• Do not put the batteries into a microwave.
• Do not open the battery.
• Do not expose battery to an open flame.
• Do not use the battery in water.
• Do not throw it into the garbage; for proper disposal of the batteries see section ”15 Disposal”.
• Be careful when operating key of battery lock.
• Never ride with key still inserted.

Storage

Please store the E-Bikeboard in a dry place. Temperature should not be higher than 60°C (140°F) nor drop below -20°C (-4°F) at any time. Keep in mind that, in particular, the batteries are sensitive to higher temperature.
