# HumsiENK HS12V320AH250BT 12V 320Ah LiFePO4 Battery

The HumsiENK HS12V320AH250BT is a 12V-class LiFePO4 deep-cycle battery listed at 320Ah, with Bluetooth monitoring and a low-temperature charging cutoff. Its stated capacity suits buyers seeking substantial RV, marine, or solar storage, but the listing's advertised energy, weight, and output claims should be reconciled before planning an installation.

Prices and deal status are the latest recorded data, not a guarantee of availability. Confirm the price and availability with the store.

## At a glance

- Bluetooth app monitoring is claimed for state of charge, voltage, current, and cell temperature.
- The listing says charging automatically stops below 32°F \(0°C\).
- M8 terminals and listed dimensions give buyers installation details to compare with their battery compartment and cables.
- The listing claims a 250A BMS and up to 3200W continuous output, but buyers should verify the ratings and compatibility for their setup.

## Pros

- Bluetooth monitoring is claimed to show several useful battery readings in an app.
- A low-temperature charging cutoff is specified, which is relevant to cold-weather use.
- The listed 320Ah capacity and 12.8V voltage provide concrete values for system planning.

## Before you buy

- 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.

## In the box

- 12V 320Ah LiFePO4 battery x1 (Included)
- Mounting screws (Included)
- Plastic insulation caps x2 (Included)
- User manual (Included)

## A good fit for

- RV, camper, trailer, boat, or off-grid solar users looking for a single high-capacity 12V-class battery, subject to confirming dimensions and system compatibility.
- Buyers who want app-based battery monitoring and a stated low-temperature charging cutoff.

## Less suited to

- Buyers who need independently verified output, battery energy, or cycle-life performance before committing to a system design.
- Installations that cannot accommodate the listed dimensions or M8 terminals.

## Customer feedback

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 capacity and voltage are listed?
The details list 320 amp\_hours and 12.8 volts. The title also claims 4096Wh, but the listing details do not reconcile that energy figure with the stated voltage and capacity.
### Can it be charged in cold weather?
The manufacturer claims charging automatically stops below 32°F \(0°C\). This is a charging cutoff claim, not a statement that the battery heats itself.
### What does the Bluetooth feature monitor?
The listing says its app can show state of charge, voltage, current, and cell temperature.
### What is included?
The stated contents list includes one battery, four M8 screws in two lengths, two plastic insulation caps, and one user manual.
