Li-ion Batterypack 16.8V, 46Wh, Flat

Flat batterypack for comfortable carrying

Specially designed for orienteers to wear comfortably on the head strap.

Maximum stored energy for long endurance

Batterypack with 4 Samsung INR18650-35E li-ion batteries each with 3450mAh capacity. These cells are the best 18650 size rechargeable batteries that currently exist. Includes a powerful protection circuit that protects the cells from undercharging, overcharging and short circuiting. The circuit adds only 6 mOhms of resistance by using state-of-the-art components. The connector is of high quality and rated up to 7A. The cable is our highly durable PUR cable that we use on all of our high performance headlamps.

Durable cable and quality connector

Broken cables and worn connector contacts are one of the most common headlamp failures. Reliability is one of our main goals, so we pay the utmost attention to this area. Thus, our batterypacks have cables and connectors that no one else has.

The connector is DC 5.5/2.1 (i.e. compatible with all manufactured headlamps and batterypacks), and we manufacture them by injection molding right here. It is rated for up to 7A current and the contact holds for a long time. The contacts hold together so tightly that spontaneous disconnection is impossible, but at the same time just enough so that they can be disconnected in worse conditions (e.g. wearing gloves in winter).

The cable is a robust PUR cable, flexible down to -30°C and maximally resistant to wear and twisting. It is grey in colour and has a fixed length (no longer twisted)!

For your information, here is the manufacturer's specification, which confirms the exceptionaldurability of the cable used:

• Guaranteed permanent application in multi-shift operation under extreme high bending stress
• Test of alternating bending cycles approx. 10 million
• High resistant to mechanical stress
• High property of alternating bending strength
• Long life durabilities through low friction-resistance by using the PP insulation
• High tensile strength-, abrasion- and impact resistant at low temperature

Weight: 240 gr.

Internal resistance (incl. connector and cable resistance): 180 - 240 milliohms.

Compatible chargers: all li-ion chargers with a charging voltage of 16.8V.
