Parallel Charge Board for JST-XH & EC5
- Product Review (submitted on April 5, 2012):
i bought this plug and connected 2 six cell packs to it and less than 30 seconds in the thing started smoking and nearly ruined 500 dollars in batteries. after further investigation it looks as though a bad solder joint or over solder spill shorted the connector.
i checked continuity between positive and negative and sure enough it has meaning that it shorted my battery upon connection causing the board to melt.
although it seems to be of good build quality this one slipped by with poor quality control and very sloppy solder joint on input side
ProgressiveRC Comment: We perform a very thorough QC of all products during assembly and prior to shipping which should catch certainly catch an error of this nature. The vast majority of parallel charge board errors occur due to a balance connector inserted one pin over from the intended location. The second most common cause of problems is connection of packs with very disparate voltages. In the event of a short on 6S the first pack connection would result in some instantaneous smoke and vaporization of the 30A copper trace. If the packs were far different voltages the event would take a few more seconds more as described above. We are happy to troubleshoot and replace as required products in these situations, but we have not been contacted regarding this issue.
