High quality Lithium ion polymer (2300mAh 3.7V) battery pack. Compatible with the BLS-71/72 Strike.

High quality Lithium (2x 18650, 2200 mAh 7.4 V) batteries.

The solar panel uses the sun's energy to recharge the lamp, suitable for all models Flea.

The USB-WERK supplies 5 V and up to 1 A current.

The E-WERK makes hub dynamo energy universally useable and supplies mobile devices with power in variable voltage and current. With the cache battery 461A, the bike-mobile power supply unit is even more universal and an even smoother operation is made possible. For some few devices cannot be powered or charged when the voltage they are fed with fluctuates or is interrupted. When one cycles slowly, the energy created by the hub dynamo and transformed by the E-WERK first drops and reaches zero when the bike stands still. Some devices react a bit touchily to these fluctuations and switch off. Other devices have to be manually switched back to powering by the E-WERK after stops.

The high output, hub dynamo powered universal power supply and charging unit For all those who do not want to go cycling without their mobile phones, GPS, MP3 players and other electronic devices and do not have access to a stationary charging station comes the "bike mobile" E-WERK.

Piggyback batteries give you peace of mind for safety and security by extending your burn times.

Replacement battery, ideal for longer excursions.

Use this Li-ion rechargeable battery as a spare or replacement for your HD HERO or HD HERO2 camera. Provides approx. 2.5hrs of record.

The 7.4v Li-ion battery pack is the same as the 2 LED's 'Epic' version - with it's 4 cells giving 5200mAh. The battery has built in charge, discharge and short circuit protection. In tests the 7.4v Li-ion battery will last up to 35hrs on low and 2h 15min on max (The burn times have been tested in optimum ambient conditions and may vary from those times shown). The PVC case is small enough to fit under most stems, top tube junctions or slip into a hydration pack or jersey pocket.

Lithium-Ion battery, 8 pieces.

POP lite Zusatzakku – Noch mehr Mobilität

Mit dem leistungsstarken Zweiakku B60 verdoppeltst Du die Leuchtdauer der B60. Das Gehäuse ist äußerst robust, da es aus eloxiertem Aluminium besteht und gegen Eindringen von Dreck und Wasser geschützt ist.

Charger for direct connection to the LIGHTSTER

The double IION -  the latest development in SIGMA rechargeable batteries is called the IION XL. It is, as its name suggests, the larger version of IION. Its 4 Li-Ion cells provide optimum energy for the POWERLED EVO and almost double the burn time of the KARMA EVO.

Small, light with plenty of Li-Ion power. It benefits in particular from its low weight (140 g), its high energy ratio and its resistance to extreme temperatures. Its low self-discharge makes the IION much more efficient than NiMH or lead rechargeable batteries.

High power replacement batteries for Tacx Lumos. Delivery 4 batteries. The batteries are not rechargable!

Special design for cycling equipped with smartphones.
