Rank #8 in Best LiFePO4 Battery 2026: 10 Ranked, and Where the Spec Sheets Slip
FEENCE H188 Mini 12V 100Ah LiFePO4 Battery
Price and rating as shown on Amazon when we collected them. Both change.
The FEENCE H188 is a 12V 100Ah LiFePO4 battery with Bluetooth, built into a smaller case than most 100Ah lithiums: the listing gives 28 x 17.7 x 18.8 cm and 10.5 kg in its bullets. It is eighth in our guide to LiFePO4 batteries, at £149.00, rated 4.5 out of 5 from 51 ratings.
Its technical table reads "Battery Capacity: 1280 Amp Hours". The same listing's own bullet says 100Ah and 1280Wh, and 12.8V x 100Ah is 1,280Wh, so 1280 is a watt-hour figure carrying the wrong unit rather than a capacity of 1,280 amp hours. That is the same unit slip we found on other batteries in this guide, and it is worth knowing before you compare this battery with anything else on capacity alone. Everything below comes from the Amazon listing, not from testing we carried out.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Nach langem Suchen und stöbern habe ich mich für diese Batterie entschieden.Sie dient als 2. Batterie in meinem Wobi , wird über die Lichtmaschine, Solar und einem Victron Energy Orion-Tr Smart DC-DC Ladebooster (Bluetooth) - 12/12V, 30 Amp geladen, über die deutschsprachige App ist es möglich, die Eistellungen anzupassen.Die Größe passt perfekt unter den Sitz von meinem Wobi Ford Transit 2013.Die Leistung wurde mit 100AH angegeben, aber laut Anzeige sind es 104Ah.Der Zellenausgleich ist sehr gut. Die Abweichungen der Zellen bewegen sich zwischen 0,01 – 0,05 Vdas sind Top Werte.Kann ich nur weiterempfehlen.”
Verified purchase“Verwende diesen Akku seit paar Monaten für meine kleine Solaranlage. Ich bin sehr zufrieden mit der Leistung. Ich würde diesen Akku sofort wieder kaufen. Auch die Anzeige über Bluetooth funktioniert klaglos über ca. 20 Meter.”

Questions people ask
What is the capacity of the FEENCE H188 12V 100Ah battery?
The technical table lists "Battery Capacity: 1280 Amp Hours". The product's own bullet says 100Ah and 1280Wh, and 12.8V x 100Ah is 1,280Wh, so 1280 is a watt-hour figure with the wrong unit, not 1,280 amp hours of capacity.
How much does the FEENCE H188 weigh?
The specification table says 11 kg. The bullet on the same page describes the battery as lightweight at 10.5KG/23.14LB. The listing does not say which of the two figures includes packaging.
What BMS and cycle life does the FEENCE H188 have?
The listing states a built-in 100A BMS, a 10-year lifespan and 4,000-15,000 cycles. The product title quotes only the top of that cycle range, "15000 Cycles".
How much energy can four FEENCE H188 batteries store?
The bullet gives up to 4P4S for a 48V (51.2V) 400Ah system with a maximum of 20.48kWh and 20.48kW load power. 51.2V x 400Ah is 20,480Wh, which matches the quoted figure.
How many ratings does the FEENCE H188 have?
The listing says 4.5 out of 5 stars from 51 ratings. The star breakdown on the same page adds up to 100: 74 five-star, 14 four-star, 6 three-star and 6 one-star.
What warranty is listed for the FEENCE H188?
The specification table's warranty field reads "5". The title claims a 10-year lifespan. Lifespan and warranty are different things, and the listing does not explain whether the 5 is years.
