Battery Power Banks and Chargers

IMPORTANT

Cold Weather

Power packs should not be charged at less than 10C, to attempt to do so at less than zero C is dangerous, in any event charge will fail.

Taking underground from freezing such as by leaving overnight in a car boot will adversely affect the burn time.

The graph below is from the cell manufacturers datasheet.

 

Compact helmet mount power packs

Helmet mount battery packs are available as 2 cell, 7 Ah @ 3.7V for WSP, EcoStar, Dragon D800, and X1000 (4V series).

We also supply 12 volt packs suitable for our current X-12 lamps plus previous 12 volt lamps such as the X5000, X6000 and MagnumStar.

All power packs are backwards compatible.

All use the very best genuine Sanyo NCR18650GA 3500 mAh Lithium Ion cells in standard power banks, and Panasonic NCR18650NSX ultra high discharge cells in power banks designed for the SAR. These are reputed to have been designed for Tesla. We do not use junk batteries. Here is the Sanyo data sheet for the technically minded.

All use yellow high performance XT60 connectors, however they are reversed between the different 4V and (8V 12V) voltage ratings, his obviates the risk of them getting mixed up.

All power packs of either voltage can be, and indeed its recommended, 'top up' charged. They cannot be overcharged.
