Battery core purchasing guide
Home :: Battery core purchasing guide
To successfully build battery packs, EVc users must choose quality cores for module reconditioning. The video and process below will help you examine cores from a supplier/source.
NuVant is now offering quality cores for purchase. Call 219-644-3231 for more information!
Process:
- Visually inspect the outer enclosure
- REJECT any cores that have:
- Painting on part or entire enclosure
- Third-party reconditioner/rebuild labels or logos
- Damage/markings
- Remove outer enclosure and inspect modules
- REJECT any cores that have:
- Leaking modules (white powder at terminals, or stains on bottom plate) – Phenolphthalein solution can also be used to detect leaks
- Modules with visible markings (for example, numbers, marker pens, tape, stickers)
- Modules with voltages below 6 V
- Non-sequential modules (QR codes should read in a sequential fashion)
Tools needed:
- Socket wrenches (to remove enclosure)
- HV plug (product description available here),
- Voltmeter (to read module voltages)
- QR code scanner (to read/store QR codes)
