Hi Guys
A little something I learned about people damaging Nanotech batteries, I hope you will agree it makes sense.

The is a small weakness in the Nanotech design, its not the lipo itself its the plastic case. The plastic case around the 4mm connectors is only around 1mm thick at the top of the case and will soften so then wire pressure can distort the plastic. If you have a high current draw motor or connectors that are high enough in resistance to heat the connections up to this temperature you may distort the battery case.

I know a few poeple that suffered from melted battery cases so I decided to take my new batteries apart and solve the problem before it happened to me and cost me money!

The wire from the Lipo to the 4mm terminal inside the battery is soldered at the bottom and is fairly rigid, I knew I needed to make the connector in the battery case more rigid and not move if the temperature got high due to a high current draw motor or connectors that are high enough in resistance to heat the connections up.

The fix I can up with was to drill 2 x 4mm holes where the small + and - symbols are on top of the battery at the highest part of the case between the connectors (make sure you don't exceed aroudn 5mm depth!), then I used a silicone sealant gun to fill each side of the battery case with silicone sealant. This holds the connectors in place if they get hot enough to melt the plastic and stops the battery becoming distorted.

Sorry if that was long winded, I hope it makes sense
