Can it run a 2000W inverter?

Yes. The 200A BMS and 2560W rated load power cover a 2000W inverter, though continuous heavy loads will drain the pack quickly. Size your bank for the runtime you need.

Does it work with a standard lead-acid charger?

Only if the charger has a lithium or LiFePO4 profile. A plain lead-acid charger may undercharge it or stop short of full capacity. Use a charger rated for 12V lithium.

Can it be charged below freezing?

No. Charging a LiFePO4 battery below 0°C damages it. Discharging in cold is fine, but keep charging above freezing.

How does it compare with a 100Ah lithium battery?

It doubles the capacity and raises the BMS current limit to 200A, so it can power bigger loads. It is larger and heavier than a 100Ah unit, so check your battery compartment.

Can I wire several together for a 24V or 48V system?

Series connection is common for 24V and 48V banks, but confirm the BMS is rated for series use and use a balancer. Parallel wiring adds capacity at 12V.

Our take on the Small Size 12V 200Ah LiFePO4 Lithium Battery

The Mehrpow 12V 200Ah is a lithium iron phosphate deep-cycle battery with a built-in 200A BMS and a rated load power of up to 2560W. LiFePO4 chemistry gives it far more usable capacity and cycle life than a lead-acid battery of similar size, and it weighs much less. The 200A BMS lets it run high-draw loads like inverters and winches that many budget lithium batteries cannot. It suits off-grid, RV, marine and solar setups where deep, repeated discharge matters more than a low upfront outlay.

Pros

Built-in 200A BMS handles high current draws
Up to 2560W load power suits inverters and winches
LiFePO4 chemistry gives long cycle life and stable output
Deep discharge without the capacity loss of lead-acid
Lighter than a comparable lead-acid deep-cycle battery

Cons

Needs a lithium-compatible charger or charge profile
Cold-weather charging must be avoided below freezing
BMS current limits still cap very large loads
Not a drop-in for every lead-acid charging system
