2 pin vs 5 pin battery connectors

[carlbikekits]

Hi,

Just looking for some advice from experienced heads.

Is it simple logic that a 5 pin is more reliable and will give more longevity than a 2 pin.

I've had 2 pin connectors and they can become unreliable after much use.

Would a 5 pin be a better choice?

Many thanks,

Carl

It would depend on the exact connectors.

Perhaps some pictures of the connectors you mean ?

A two pin battery connection means the system is dumb generic one with no other comm's involved, a generic battery that has 4 or 5 pins still only uses two pins the others unused or a pair may be used and wired in parallel for on bike charging should the battery charge point be in an awkward place.

Or the extra connections can be a serial data bus sending data from the battery system to the controller etc. For instance, using diagnostic tools on the Bosch system, it can tell the workshop how many charge and discharge cycles that battery pack has done. It also will have serial number information,and or the ability to lock out a cloned battery.
