What is the difference between the two versions?

One has high-temperature cutoff only. The other adds low-temperature cutoff, which blocks charging below freezing to protect the cells. Choose the low-temp version if you charge in cold weather.

Can I use it as a direct replacement for a lead-acid battery?

Yes, it is a 12V 100Ah drop-in for most deep-cycle lead-acid applications. Make sure your charger or solar controller has a lithium (LiFePO4) charge profile.

How long will it last?

Solar Super Sonic rates it for up to 15,000 deep cycles. Real lifespan depends on depth of discharge, temperature and charging habits.

Does the BMS protect the battery?

Yes. The built-in BMS balances charging and protects against over-current and over/under-voltage.

Can I charge it below freezing?

Only on the version with low-temperature cutoff, and even then charging pauses until the battery warms above the cutoff. The high-temp-only version should not be charged in freezing conditions.

It suits RV and boat house loads, trolling motors and small solar banks. For large inverters, check that the BMS current rating covers your draw.
