Before you start
- Isolation order for any battery work: battery first — per Isolation & Shutdown.
- Torque and cable sizes are platform items: take them from Kent M1 Battery Wiring or Kent G3 Battery Wiring, never from memory.
- PPE per PPE & Tools: insulated gloves and tools for all terminal work.
Handling and moving packs
- Packs are heavy — use mechanical handling and correct lifting technique; never drag a pack by its cables or terminals.
- Do not stack loose packs during a move; keep the pack upright and protected from impact.
- Lithium transport falls under dangerous-goods rules (UN3481 class) — packs travel in their packaging, by the book.
Storage rules (warehouse, dealer stock, site delays)
- State of charge before storage: 30 % to 60 %. Never store a pack full or empty.
- Storage life is temperature-tiered: 12 months at −20 to 35 °C · 3 months at −20 to 45 °C · 1 month at −20 to 55 °C.
- Store ventilated, clean, dry, dust-protected, no condensation, no direct sunlight on the equipment.
Damaged, leaking or misbehaving packs
- A pack that is swollen, dented, leaking, hissing or smells burnt is out of service on the spot: isolate the bank if safe to reach, keep people away, and call Kent service.
- Faulty batteries are never reused and never sent as normal freight — disposal goes through Kent’s channel.
- Keep used or damaged packs away from high temperature, direct sun, humidity and corrosive environments while they await collection.
What no one opens in the field
Cells, BMS boards and the pack’s internal protection are factory territory — there are no field-serviceable parts inside a pack, and the inverter’s battery-circuit fuse is not field-replaceable either. Escalate, do not open.Common mistakes
- Storing “spare” packs full “so they’re ready” — the storage band is 30–60 % SOC.
- Working on terminals with rings or a metal watch strap still on.
- Treating a swollen pack as “still works, still ships” — it is a hazard, not stock.
- Jump-charging a dead pack from a bench supply — wake it the official way; see Not Charging / Not Discharging.
When to escalate
Escalate to Kent New Energy service only — through your registered Kent partner channel or the Kent service desk details on your work order. Do not contact any third-party or component-manufacturer support line for a Kent-branded system: tickets outside the Kent channel are not tracked, not covered, and can void warranty handling.
