Guppy – Battery Spring

Semi-collapsible battery spring for all Guppy versions.

Collapsible springs cannot provide any dependable battery protection or user safety, since they only react only after a battery has overheated. By that time, any battery will have sustained serious damage, exposing the user to serious risks.

Therefore, using a primary means of battery protection such as a dedicated circuit board, a drop-in protection module, or a fuse, should be considered as absolutely necessary if you are concerned about safety.

These springs have a very thick wire diameter, which contributes to minimizing voltage drops. They do not provide sufficient safety.

Options

Guppy springs are manufactured in 3 different variations, each with its own pros and cons:

• Plain, unplated brass springs provide good performance, but their top/bottom contact areas must be routinely cleaned. The standard option.
• Silver-plated, brass-core springs provide the best conductivity. However, pure silver has poor mechanical properties, which means that the plating will slowly wear off. To remedy this, silver-plated springs have an additional corrosion/stress resistant under-plating, which, however, is not as conductive as silver, but still better than un-plated brass. A good choice for the best possible performance and still better than un-plated brass even if the top layer wears off after many months of use.
• Rhodium-plated, brass-core springs provide great conductivity, but not as good as pure silver. However, Rhodium is an extra-durable plating material, which will not tarnish in any environment. Plus, it has a bright, grey-silver tone, that looks simply unreal. Its only real downside is, is course its price.
