Slinger Bag Tennis Ball Machine Battery Rebuild
$99.00 USD
Restore your original Slinger Bag battery instead of waiting for a replacement battery to become available.
This mail-in Battery Revival service is designed for the Slinger Bag KMD-SB-4660 rechargeable lithium-ion battery, originally rated at 14.4V, 6.6Ah, and 95Wh.
The original battery uses a 12-cell, 4S3P lithium-ion configuration. During the rebuild, we replace all 12 internal cells with new 3000mAh lithium-ion cells, increasing the estimated capacity from 6.6Ah to approximately 9Ah.

Important Service Information
This listing is for a battery rebuild service, not a replacement battery. You must send your original Slinger Bag battery to United Lithium Solutions.
The listed price covers complete cell replacement when the original housing, connectors, wiring, and battery management electronics remain reusable. Damage to the BMS, charging port, discharge connector, housing, or wiring may require an additional quote.
Final capacity may vary slightly based on cell availability, testing results, and the usable internal space of the original housing.
