Caveats
- Buying the station and the SP037 as two items with BULKRATE came to $852.62 in our 2026-10-29 cart test, less than the kit SKU with a 10% code, but the SP037 sold on its own showed sold out on 2026-11-07, so the kit is the way to buy the pair for now.
- Station weighs 29 kg (63.9 lb).
- ALLPOWERS gives the cycle rating as '3500+' with no end-of-life percentage.
Affiliate link: if you buy through it, the merchant pays us a commission at no cost to you; that commission pays for the cart tests behind every code here. Price, availability and each code were checked on the merchant's own US store on the dates shown; they change, so the store's checkout is the source of truth. Full disclosure.
