Why it matters
At $293.38 for the pair, this Dyness 2 pack is at the lowest price CamelCamelCamel shows for the last 3 months (it dropped from $325.98 to $293.38 on Sep 7, 2026, and has held there). Its tracked average is $318.62.
The all-time tracked low is $289.78 (Jul 17, 2026), so today is within about $3.60 of the best price we can find on record. That is a real low, not just a gap from the $325.98 list price.
About $0.11 per Wh is a strong number for a name-brand 12V LiFePO4 battery. Dyness is an established storage battery maker, not a no-name reseller.

Watch out for
- This is a third-party seller price on Amazon, not sold by Amazon itself. Check the seller and return terms before you buy.
- It shows a "Limited time deal" badge on Amazon, so the price can end without notice.
- Confirm the BMS current rating fits your inverter, and plan proper fusing and cabling for any parallel or series setup.
