Our take on the CTOLITY CT100-12 12.8V 100Ah 1280Wh LiFePO4 Battery

The CTOLITY CT100-12 is a 12.8V 100Ah lithium iron phosphate battery rated at 1280Wh. It uses Grade-A cells and is rated for 4000+ cycles at 80% depth of discharge with a claimed 10-year lifetime. A built-in 100A BMS adds overcurrent and low-temperature protection, cutting off charging below 32°F. At about 23 lb it is far lighter than a comparable lead-acid block, which makes it a drop-in upgrade for RV, trolling motor and off-grid use.

Pros
  • 1280Wh capacity from a 100Ah, 12.8V pack
  • 4000+ cycles at 80% DOD, rated for a 10-year life
  • Built-in 100A BMS with low-temperature charge cut-off
  • About 23 lb, much lighter than an equivalent lead-acid battery
  • Grade-A cells
Cons
  • Low-temperature cut-off blocks charging below 32°F, so cold-weather charging needs warming
  • 100A BMS limits continuous draw to roughly 1.2kW
  • No Bluetooth or app monitoring mentioned
  • Charging below freezing is not possible without external heat

What reviewers say

  • 4.8 / 552 ratings

Rated 4.8 out of 5 across 52 ratings. Buyers treat it as a solid, lightweight replacement for lead-acid in RV and off-grid setups.

What people mention
  • WeightPraisedOwners note it is far easier to carry and install than the lead-acid battery it replaces.
  • Cycle lifePraisedThe 4000+ cycle rating at 80% DOD is a draw for buyers planning long-term off-grid use.
  • BMS protectionPraisedThe built-in 100A BMS and low-temperature cut-off are seen as useful safeguards.
  • Cold chargingMixedThe 32°F charge cut-off protects the cells but limits use in freezing conditions.

About the CTOLITY CT100-12 12.8V 100Ah 1280Wh LiFePO4 Battery

The CTOLITY CT100-12 is a 12.8V, 100Ah lithium iron phosphate (LiFePO4) battery with 1280Wh of energy. It uses Grade-A cells and is rated for 4000+ cycles at 80% DOD and a 10-year lifetime.

A built-in 100A battery management system (BMS) protects the battery. A low-temperature cut-off stops charging when temperatures fall below 32°F. Spacers inside help protect the battery from vibration on rough terrain and choppy water.

It weighs 10.5±0.5 kg (23.15±1.1 lb). Compared with a 12.8V 100Ah lead-acid battery, it offers twice the energy at one-third the weight. It can be charged with a LiFePO4 battery charger, a solar panel, an RV system DC-DC charger or a generator.

Questions and answers

How many watt-hours does it store?
1280Wh, from 12.8V at 100Ah. That is roughly the usable energy of a 100Ah lead-acid battery, but more of it is actually delivered.
Can it replace a lead-acid battery directly?
Yes for most 12V deep-cycle uses. It weighs about 23 lb versus 60 lb or more for lead-acid, and it needs a lithium-compatible charger or charge profile.
Can I charge it in freezing weather?
No. The BMS stops charging below 32°F to protect the cells. Discharging still works in the cold, and charging resumes once the battery warms above that point.
How much current can it deliver?
The 100A BMS caps continuous output at about 1.2kW. That suits trolling motors, RV loads and modest inverters, but not large whole-home inverters.
How long will it last?
CTOLITY rates it for 4000+ cycles at 80% depth of discharge and a 10-year lifetime. Shallow discharges and moderate temperatures extend that further.
Does it have Bluetooth monitoring?
No. There is no app or Bluetooth monitoring listed, so state of charge is read from your charger, shunt or inverter.
Where is the CTOLITY CT100-12 12.8V 100Ah 1280Wh LiFePO4 Battery cheapest?
