Chargis kit

A battery spot welding machine built for makers — everything you need to spot-weld your own packs and walk away with power in your hands.

Chinese kit vs Chargis kit

Same idea on paper — very different in the box.

Chinese kit

  • Unknown PCB design
  • PCB only
  • High probability of failure

Chargis kit

  • Designed for quality grade
  • Consistent quality
  • Well protected

Imagine:

You unbox the Chargis kit on a quiet afternoon. The bench is clear, the cells are lined up, and for the first time the welder in your hands is yours — not a mystery PCB from overseas, but a tool designed to hold a clean, consistent spot. By evening, a pack sits in front of you. Real. Tested. Ready.

Modular battery pack with cylindrical cells and BMS built using the Chargis kit

Welds you can trust

Every cell joined with the Chargis kit means even pressure and repeatable spots — not the weak bridges you get from a bare-board import. You build a pack that holds together because the tool was made for the job.

Solar panel and battery pack powering lights, fridge, tools, and charging

Power for what you actually use

Size the pack around your life — lights, fridge, tools, a laptop on the desk. The Chargis kit is how you get from cells in a box to a battery that feeds what matters, not a gamble on whatever the cheapest listing shipped.

Solar panels capturing sunlight to charge a battery pack

Solar in, storage ready

Panels on the roof, energy in the pack. The Chargis kit is the step between sunlight and stored power — the pack you built becomes the buffer that keeps evenings bright and mornings effortless.

Solar and battery system powering a cabin, workshop, van, and outdoor event

Anywhere the grid does not reach

Cabin, workshop, van, stage in a field — the same Chargis kit-built pack travels with you. Imagine welding it once, then living off it for years in places lines and bills never followed.

Where the grid won't find you

Solar on the roof, your pack in the wall, evening light in the windows. That is what the Chargis kit starts — not a hobby project on the bench, but the beginning of a place the grid was never invited to.
