Turnigy Bolt Battery 500mah 2S

Dear HK,

I write you in the name of our local RC club

We were glad when you introduced the Turnigy Bolt batteries. We have bought the necessary chargers and a few Bolt batteries.

Now we are satisfied their performance and we would like to buy more.

It will be highly appropriated to check when will be it available.
We look forward to your feed-back.

Thank you in advance.
