The TCBWORTH 12V 100Ah is a Bluetooth-equipped LiFePO4 deep-cycle battery at £139.00, ninth in this guide. It is a small unit for the capacity — the listing gives its dimensions as 9.02 x 5.43 x 8.19 inches — with a 100A smart BMS, and the seller pitches it at people converting away from lead-acid, quoting 20.7 lb in the bullets against 9.5 kg in the spec field. Those two agree (20.7 lb is about 9.4 kg), which is worth saying because plenty of sheets in this guide do not.

The mismatch on this one is a name, not a number. The title, the bullets and the model number all say LiFePO4; the spec field says "Battery Type: Lithium Ion". LiFePO4 is a lithium-ion chemistry, so the field is not exactly wrong, but it is not the claim the title makes either. On money, 12.8V x 100Ah is 1,280Wh, so £139.00 works out at £108.59 per kWh — above the £101.55 per kWh we get from the Rvpozwer 12V 100Ah, below the £139.65 per kWh of the ECO-WORTHY 48V 100Ah. Its Best Sellers Rank reads 115,449 in Business, Industry & Science and 197 in Deep Cycle Batteries, well behind the two FEENCE listings at 12,977 and 26. And the star breakdown deserves a flag of its own: the bars run 79 / 5 / 8 / 8, which adds to 100, while the listing states 50 ratings. The page does not say whether those bars are counts or percentages, so one of the two numbers is not doing what it looks like. Everything on this page comes from the Amazon listing as it was published, not from any test of our own.

## Questions people ask

**What capacity is the TCBWORTH 12V 100Ah battery?**

The title and bullets say 100Ah at 12.8V, which is 1,280Wh, or 1.28kWh.

**Is it LiFePO4 or lithium-ion?**

Both names appear. The title, the bullets and the model number say LiFePO4; the spec field says "Battery Type: Lithium Ion". LiFePO4 sits inside the lithium-ion family, but the listing uses the two terms as if they were interchangeable.

**Can I wire several together?**

One bullet says the 12V 100Ah supports series and parallel connection up to 4S4P. The same bullet then recommends ordering TCBWORTH's 24V, 36V or 48V batteries for series use, so for a series bank the listing points you at a different product.

**What charging voltage does it want?**

The bullets recommend a charging voltage of 14.6V for a 12.8V LiFePO4 battery. The sentence that follows, giving the recommended charging current, is cut off in the listing.

**What discharge current can it take?**

The bullets give a maximum continuous discharging current of 100A, with an inrush current of 200A for 3-5 seconds.

**Does the BMS protect it in the cold?**

A bullet heading lists a low-temperature cut-off alongside the Bluetooth 100A BMS, so the BMS steps in at low temperature. The listing does not give the temperature at which it cuts off, because the sentence is truncated.
