What to know before buying

Listing details to confirm

The listing is inconsistent about weight: the title says 58.6lbs, a feature claim says 58.69 lbs, and the details list 58.7 pounds. It also pairs 320 amp_hours at 12.8 volts with a 4096Wh claim, which does not match their simple product, and the 250A BMS and 3200W output claims are not fully explained. Confirm the applicable ratings and fit for your system before purchase. The stated low-temperature cutoff applies to charging, not a general claim about all operating conditions.

The supplied evidence includes only a very small aggregate rating sample and no customer review text. The positive rating signal is therefore limited and cannot establish how the Bluetooth monitoring, cold-weather cutoff, or claimed output perform in use.

Frequently asked questions

What is included?

The stated contents list includes one battery, four M8 screws in two lengths, two plastic insulation caps, and one user manual.
