pic: Battery connector.....

[Al Skierkiewicz]

Guys,
Hold on so we get some real facts listed. The SB 50 was not introduced when we went to the IFI controllers. It became mandated much later. WildStang used a similar connector for many years prior to the start of the SB50. The battery is capable of 600+ amps when fully charged and that drops off with discharge. The main breaker is also capable of 600+ amps for several seconds without trip. The SB50 is rated for 50 amps continuous, that is every hour for every day, for ever. The rating is verified by UL testing based on temperature rise over long term use, that is more than a day at continuous current. The test includes a safety margin meaning a fixed amount of excess current will not raise the temperature beyond the safe limits set by the UL test. The UL test data is on the Anderson website if you search for it. As I remember the safety margin is like 100%. That is 100 amps continuous for more than a day without exceeding the set temperature.
Andrew, there are many reasons for connector failure, that is why I would like to look at the connector if possible. I have seen some failures, I would like to add to my data with your connector.
Please remember that the 120 amps forktruck connector may be terminating a 24, 36 or even higher voltage. Please do not be lulled into believing your are talking apples and apples when just looking at the connector.
