Rank #2 in Best LiFePO4 Battery 2026: 10 Ranked, and Where the Spec Sheets Slip
DCHOUSE 12V 100Ah Bluetooth LiFePO4 Battery
Price and rating as shown on Amazon when we collected them. Both change.
The DCHOUSE 12V 100Ah is a Group 24 LiFePO4 battery with built-in Bluetooth monitoring and a low-temperature charge cut-off, listed at £159.99 and at number 2 in this guide. The listing carries 4.8 out of 5 from 66 ratings, a rank of 4 in Deep Cycle Batteries, and a claimed 15,000 cycles across a 10-year service life.
Two numbers on that page do not sit together. The star histogram adds up to 100 — 89 five-star, 6 four-star, 3 three-star and 2 one-star — while the rating count alongside it says 66. The spec table also calls the chemistry "Lithium Metal", where the title and bullets both say LiFePO4. On the arithmetic that does check out: 12.8V x 100Ah is 1.28 kWh, so at £159.99 the pack works out at roughly £124.99 per kWh. Everything on this page comes from the Amazon listing as published, not from any testing we carried out.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Great. Equivalent lead acid battery lasted about an hour before it was flat using an electric motor on my small rubber dinghy. After two hours use, this still showed 65% remaining. And it's probably half the weight.”
Verified purchase“Bought a battery that had a charging problem. Messaged and was ran through a few problem solving tasks and none of them worked.Was subsequently sent out a replacement very quickly that charged perfectly.Exemplary customer service, deserves more than 5 stars. Bought a 2nd battery from them based on this service.Excellent company to buy from.”

Questions people ask
What is the DCHOUSE 12V 100Ah's price per kWh?
At the listed £159.99 and 12.8V x 100Ah (1.28 kWh), it comes to about £124.99 per kWh. That is more per kWh than the Rvpozwer 12V 100Ah at £101.55 and less than the ECO-WORTHY 48V 100Ah at £139.65.
Does the DCHOUSE 12V 100Ah have low-temperature protection?
The listing says the BMS cuts off charging once the temperature sensor reads below 32°F, and cuts off discharge at a lower point. The bullet is cut off mid-sentence before that discharge figure is given, so the listing never states it.
What chemistry does the DCHOUSE 12V 100Ah use?
The title and bullets describe a LiFePO4 battery with Class A cells tested to UL/UN38.3. The spec table lists the Battery Type as "Lithium Metal", which is a different chemistry from lithium iron phosphate.
How many ratings does the DCHOUSE 12V 100Ah have?
The listing shows 4.8 out of 5 from 66 ratings. Its star histogram separately totals 100: 89 five-star, 6 four-star, 3 three-star and 2 one-star.
What does the Bluetooth app show on the DCHOUSE 12V 100Ah?
The listing says the DCHOUSE app connects over Bluetooth with a signal range of 5-10 metres and reports SOC, voltage and current.
What warranty comes with the DCHOUSE 12V 100Ah?
The spec table states a 3 year warranty; the bullet wording is "3 years of reported service". Support is through Amazon or the after-sales address in the manual.
