Can it run a 2000W inverter?

Not comfortably. A 2000W inverter can pull close to 170A at 12V, well above the 100A continuous discharge rating. Size your inverter to stay under 100A, or use two batteries in parallel.

How does it compare with lead-acid?

It weighs far less, delivers more usable capacity and is rated for at least 4000 cycles versus a few hundred for flooded lead-acid. It also needs a lithium-compatible charger set to 14.4V-14.6V.

Can I charge it below freezing?

The listing gives no low-temperature charging cutoff, so avoid charging below 0°C (32°F). Discharging in cold is generally fine, but charging a cold lithium battery can damage it.

What charger should I use?

Use a lithium LiFePO4 profile with a max charge voltage of 14.6V and a standard charge current of 10-50A. A lead-acid charger without a lithium mode can overcharge it.

One 12.8V 100Ah LiFePO4 battery, a use manual and two M8 bolts. No charger or mounting hardware is included.

Can I wire two in parallel?

Yes. Two in parallel give 200Ah at 12V, and the combined 200A discharge covers larger loads. Keep cable lengths equal and charge them together.

Our take on the Enegitech 12V 100Ah LiFePO4 Battery

The Enegitech 12V 100Ah is a lithium iron phosphate deep-cycle battery rated at 12.8V with a 100A maximum continuous discharge. It is built for RVs, boats, trolling motors, solar and small backup systems, where its 4000-plus cycle life and lighter weight beat flooded lead-acid on longevity. Its 100A discharge ceiling is lower than the 200A some premium lithium rivals allow, so it suits steady loads rather than big inverters or high-draw starters. Owners rate it 4.4 out of 5, with most praise going to value and usable capacity and some complaints about capacity and cold-weather charging.

What reviewers say

4.4 / 534 ratings

Owners give it 4.4 out of 5 and mostly praise the value and the capacity it delivers in RV and solar setups. A few report less usable capacity than expected, and cold-weather charging is a recurring concern.

What people mention

CapacityMixedMost owners get close to the rated 100Ah, but some report noticeably less usable capacity.
ValuePraisedOwners say it undercuts premium lithium brands while covering the same basic job.
Cold chargingCriticisedReviewers warn that charging below freezing needs care because no low-temperature cutoff is listed.
InstallPraisedThe M8 bolt terminals and standard footprint make swapping out a lead-acid battery straightforward.
Discharge limitMixedThe 100A continuous limit is fine for most RV and trolling loads but rules out big inverter draws.
