Great transaction. Fast shipper from China. Battery pack exactly as described and required polarity reversal on the plug before installing in the big blue party speaker (just as described). Only ding is the battery pack shipped with 26 gauge wires whereas the OEM battery was connected with 24 gauge wires. Instead of changing the pinning in the connector to reverse polarity I cut the original battery wiring harness and solder spliced it to the new battery pack to reduce voltage drop.
