Key Features
- 84.4Wh Capacity
- Lithium Iron Phosphate Chemistry
- Evironmentally Friendly, No Toxic Metals
- Dedicated Celestron Mount Power Port
Employing a more environmentally friendly battery chemistry than previous iterations Celestron's PowerTank Lithium 84.4 Wh Power Supply gives you the power required to run your motorized Celestron mount with the added capability of charging small electronics such as smartphones, tablets, and cameras. An integrated white LED flashlight, with two output settings, gives you the illumination you need to get to your observation point and set, and a separate red LED light allows you to perform tasks like swapping eyepieces or attaching filters without affecting your night-adjusted vision. The PowerTank has a compact form factor at 7.5 x 3" and weighs just 2.25 pounds. Two straps are included so you can either hang it or attach it to the tripod, but if you want to leave it on the ground it has an IP65 rating, making it dustproof and water-resistant.

what’s the best way to keep this battery charged or uncharged?
The Celestron PowerTank Lithium should be kept at around 40-50% State of Charge to be ready for immediate use – this is approximately 3.8 Volts per cell – while tests have suggested that if this battery type is kept fully charged the recoverable capacity is reduced over time. The voltage of each cell should not fall below 2 volts as at this point the anode starts dissolving causing copper shunts to form which will cause an irreversible loss of capacity. Similarly lithium based batteries can be damaged by over charging which causes the cathode to decompose.
