How It's Built
How every Domes Power pack gets built.
From cell selection to the final CD stud weld, here's what it takes to assemble a battery pack that holds up off-grid.
01
Cell selection
Sunwoda LF314 prismatic cells are matched and tested before assembly begins.
02
Pack configuration
Cells are wired in series — 8S for 24V, 16S for 48V — to hit the target voltage and capacity.
03
CD stud welding
Terminals are welded with our capacitor discharge stud welder for a low-heat, cell-safe bond.
04
BMS integration & test
Each pack is fitted with a JKBMS and tested before it ships.

Frequently Asked Questions
Batteries, welders, and off-grid builds.
What's inside a Domes Power battery pack?
Sunwoda LF314 prismatic LiFePO4 cells wired in series, protected by an integrated JKBMS, with terminals CD-stud-welded in-house.
What's the difference between the 24V and 48V packs?
The 24V pack is an 8S configuration at roughly 8kWh. The 48V pack is a 16S configuration at roughly 16kWh. Both use the same Sunwoda LF314 cells and JKBMS.
Why would I buy the stud welder instead of a finished pack?
If you're building your own packs, the CD stud welder is the same tool Domes Power Group uses on its own assembly line for low-heat, cell-safe terminal welds.
