The iOptron PowerWeight rechargeable battery pack is a very portable and convenient power source for your GOTO mount in the field.

Use this battery pack in place of a traditional counterweight with a weight of 3.2kg to reduce your total equipment weight. The included power cord connects drectly to the mount to avoid long extension cords.

Inside the counterweight are 6 heavy duty spiral wound valve-regulated lead-acid (VRLA) battery cells. The 8 amp-hour power pack provides power for operation of your GOTO telescope mount out in the field. The battery does not have a memory effect like other types of battery.

An indicator light on the battery charger tells you the battery charging status. RED indicates the battery is recharging and GREEN indicates the charge is complete. The charging process automatically stops when the battery is full.

The PowerWeight comes with instructions, a mains charger (fitting a standard two-prong international shaver power socket), and a coiled flexible cable to plug the battery into the mount's power supply.

There are two sockets on the PowerWeight TM ,either of which can be used for power drawing or charging.

Warranty note: We have recently become aware of UK companies and inviduals purporting to offer "hypertune" modifications, servicing and repair for iOptron products. There is no company in the UK authorised to repair iOptron products other than Altair Astro (official iOptron agents). We have had mounts back in for servicing after they have been modified with incorrect parts, lubrication, and internal adjustments. We will do our best to help reverse these changes at a reasonable price to get you going again. Any work which is not performed by Altair Astro will invalidate your warranty. If you require servicing or spares from Altair Astro, please contact us, or ask your official dealer to contact us on your behalf.
