The FEENCE 12V 140Ah H190 Bluetooth is the fifth entry in this guide: a 12.8 V lithium iron phosphate battery at £169.00, rated 4.5 out of 5 from 21 ratings. The seller describes it as the same H190 footprint as the brand's 12 V 100 Ah model with 40% more capacity, and lists Bluetooth monitoring through a phone app, low-temperature charge protection and expansion up to a 51.2 V 560 Ah bank in a 4S4P layout.

Its headline number is the one to check. The product title says "1920kwh Output"; the bullets in the same listing say "MAXIMUM ENERGY OUTPUT 1792 WH"; and 12.8 V multiplied by 140 Ah comes to 1,792 Wh, or 1.792 kWh. So the title is wrong in the figure and wrong in the unit — 1920 kWh would be a thousand times the energy the pack holds, and 1,792 Wh is the number the rest of the advert supports. The Best Sellers Rank shown here (12,977 in Business, Industry & Science; 26 in Deep Cycle Batteries) is identical to the rank on the other FEENCE battery in this guide, so those two figures can only describe one of the two packs. Everything on this page comes from the Amazon listing, not from any testing we carried out.

## Questions people ask

**How much energy does the FEENCE 12V 140Ah hold?**

The bullets state a maximum energy output of 1792 Wh, which is 12.8 V multiplied by 140 Ah. The product title says "1920kwh Output" instead, which does not match either the voltage or the amp-hours.

**Is 1920kwh the same as 1792Wh?**

No. 1792 Wh is 1.792 kWh, so the title figure is about a thousand times larger, and 12.8 V x 140 Ah does not produce 1920 of anything.

**What BMS does this FEENCE battery have?**

The title says 150A BMS. The bullet on output says a maximum continuous charging current of 140 A, and the discharge figure is cut off in the listing text.

**Does the FEENCE 12V 140Ah have Bluetooth?**

Yes. The listing says the battery connects to the mobile app, where you can view battery voltage, current, power and battery capacity.

**How far can this battery be expanded?**

The listing says up to a 51.2 V 560 Ah system in a 4S4P configuration, and that charging stops below 0°C and restarts at 5°C.

**How does it compare on price per kWh?**

At £169.00 for the 1792 Wh in the bullets it works out at about £94 per kWh, against the £101.55 per kWh quoted for the Rvpozwer 12V 100Ah and the £139.65 per kWh for the ECO-WORTHY 48V 100Ah elsewhere in this guide.
