Need somethingwe don’t list?
We build these ourselves, which means the catalogue is a starting point rather than a limit. If you need a larger bank, a different form factor or a specific terminal layout, tell us what the build needs and we will quote it.
What we can change
Most of it, honestly.
Capacity
THE DON is listed at 110ah because that is what most builds want. We have built it considerably larger. If you need more, ask — the cells and busbars scale.
Form factor
Case dimensions can change to fit the space you actually have. Send us measurements and we will tell you what fits.
Terminal layout
Number and position of lugs and direct-wire points. Our busbars are machined in-house, so this is a design change rather than a special order.
Chemistry
Sodium ion, LTO or NMC depending on your charging voltage. We will tell you which one your system actually needs, including when it is the cheaper one.
Before you ask
What makes a good request.
Tell us the load, not the battery
“I need 2,000 amps” is more useful than “I want a 300ah pack.” Give us total RMS wattage, your charging voltage and how you play it, and we will work out the pack. Half the time the answer is smaller than people expect.
Measure the space
Length, width and height of the actual cavity, and where the terminals need to face. A pack that does not fit is worse than one that is slightly small.
Custom takes longer
A custom pack goes behind the standard build queue, not in front of it. Expect a longer lead time and a real date rather than a guess.
The process
What happens after you send it.
- You send the request. The more of it you fill in, the faster we can price it. If you do not know a number, leave it blank — we would rather have an honest gap than a guess.
- We read it and work the numbers. A person, not a form robot. Often the answer is that something we already build does the job cheaper, and we will tell you that.
- You get a spec and a price. Capacity, chemistry, case size, terminal layout, lead time and cost — a real figure rather than a range.
- You decide, then we build. Custom packs go behind the standard queue, not in front of it, so you get a real date once the build is scheduled.
Some requests we turn down — a build that is not worth what it would cost you, or one we cannot do properly. We would rather say so than take the money.
