Power tank for skywatcher 127 Mak

[Beardy30]

Hi all which PowerTank should I get for the skywatcher 127 Mak ? Any recommendations? 

[Beardy30]

And also for the Nexstar 6 SLT

What are you going to power with the portable supply? Mount, dew control, laptop etc? There are much better items than the Powertanks. Both Powertanks I owned gave up after a few months. Once we know your power requirements we can advise on suitable items.

No laptop - just to power the goto mount

I use the small celestron lifepo4 to run a virtuoso goto mount. It's very light and power lasts ages I get 7+ nights of use from one charge and it has much smaller environmental footprint then those lead acid heavy units.

The unit I use is 12v

Thanks

I use the Celestron LiFePO4 7 as well. Works great for not too much equipment as soon as dedicated camera's and/or laptops get involved, you better choose the 17 Amp version.

Thanks , looks expensive though 

[Waldemar]

Good stuff costs...

[Beardy30]

Very true !

It's not expensive when you factor in it will take thousands on charge cycles compared to a few hundred on the lead acid, and it is better environmentally.

[Waldemar]

And not to forget the provided voltage is far more stable...

This gives you an idea of typical current consumption

These are my power sources

The 6V battery packs are borrowed from my radio-controlled model sailing yachts.
