Maine lithium batteries — climate and freight, not a swapped city name

January design temps on the coast sit near 0 F. If the charger can push current into a frozen cell, you need a BMS that refuses the charge. ChargeX is a US manufacturer (CAGE 93CZ2). Cold-weather lithium batteries for Maine off-grid, cabin, and marine use. Tell us marine, solar, RV, or backup — Maine is the climate line, not the product.

CAGE 93CZ2

UN38.3 transport docs on request. DUNS 109774429. We do not publish a star rating we cannot source.

This rail: House banks, Group 24/27/31 drop-ins, small inverters

Typical size: Typical 100–400Ah; parallel for more

What actually fails

  • January design temps on the coast sit near 0 F. If the charger can push current into a frozen cell, you need a BMS that refuses the charge.
  • Freight to Maine is a UN38.3 and carrier conversation, not a local fake address.

How we quote it

  • Pick the use (boats, camps, and off-grid) and the voltage that equipment already wants.
  • We quote landed freight. We do not invent a regional partner name.

Sensible up to roughly 2 kW continuous inverter load. After that, step up voltage or parallel with thicker cable.

If you delete the voltage, the Maine constraints above should still make sense. That is the point.

Maine: the constraints that survive a find-and-replace test

January design temps on the coast sit near 0 F. If the charger can push current into a frozen cell, you need a BMS that refuses the charge. Typical jobs: boats, camps, and off-grid. ChargeX ships LiFePO4 with UN38.3 documentation. Install stays with a licensed electrician in Maine. Sensible up to roughly 2 kW continuous inverter load. After that, step up voltage or parallel with thicker cable.

Spec note

If you only have a Maine shipping address, say what the pack is doing. Climate changes the charge-temp story; it does not change LiFePO4 into a different chemistry.

Questions we actually get

Do you warehouse batteries in Maine?

We manufacture and ship from the US. There is no invented Maine storefront on this page. Freight, duties, and UN38.3 paperwork are the real constraints — ask sales for a landed quote.

What is different about a pack for Maine versus somewhere else?

January design temps on the coast sit near 0 F. If the charger can push current into a frozen cell, you need a BMS that refuses the charge.

Which voltage should I pick if I am in Maine?

Voltage follows the equipment, not the map. Boats and RVs are usually 12V or 24V. House solar and telecom are usually 48V. If you only know the place, start with the load.
