Hi,
Have a nice day.
You can find it in Sim Lim Tower (Sim Lim Square also got but only a few shops). I'm not sure the exact cost, but a 7AH SLA (Sealed Lead Acid) Battery and simple charger should cost around than S$50. But you need to DIY the power connector to the scope.Hi, I want to buy a portable power tank for my goto scope. I heard that it is available in Sim Lim. Which shop and how much?

I did just that last evening with a 17Ah gel acid battery, on a laptop, GM8 with Gemini, and 2 Heaters. And guess what, it wouldn't last 3 hour! It turn out that the most power hungry device is not the heaters but the laptop.How long will a 17Ah battery run on average with a GOTO scope, heaters and a laptop attached?
