Sodium-Ion vs LiFePO4
A cold-climate comparison of sodium-ion and LiFePO4 for engine starting: discharge at −40°C, cranking bursts, voltage windows and cycle life, from cell data.
500W, 1000W, 3000W or 5000W? Sizing a Portable Power Station
How to size a portable power station: separate output from capacity, add up real loads, and match the 500W, 1000W, 3000W and 5000W classes to actual uses.
Replacing Lead-Acid Forklift Batteries with Sodium-Ion Packs
A fleet guide to switching electric forklifts from lead-acid to sodium-ion: 24V–96V classes, tray and counterweight fitment, opportunity charging and cold stores.
What these guides cover
Three long-form guides, each built around a decision buyers actually face. The first compares sodium-ion and LiFePO4 for cold-climate starting, cell data included. The second is a sizing method for portable power stations — output versus capacity, worked through with real load lists. The third walks a forklift fleet through replacing lead-acid traction batteries with sodium-ion packs, class by class, chargers included.
How to read the numbers in these guides
Each guide works through the sizing arithmetic step by step, so you can rerun it with your own loads, hours and temperatures. Where a decision turns on something no catalogue can know, like your fleet's shift pattern or your market's coldest night, the guide says what to measure instead of guessing at it.
From a guide to a shortlist
If a guide narrows the choice, the product pages carry the specifications, and the inquiry form is where a shortlist becomes a quotation. Tell us which guide you came from and what your own numbers look like — the reply will meet you at that level, not start again from the beginning.
