Is $219.99 for two batteries a good price?

At $219.99 for the pair at Eco-worthy as of November 5, 2026, you pay about $110 per 100Ah battery. That is low for LiFePO4 with Bluetooth and cold protection, and it is the only new price listed.

Can I use these to replace lead-acid batteries?

Yes. They are Group 24 size, so they fit many lead-acid trays, but you need a lithium charge profile. Do not use an old lead-acid charger set to flooded or AGM mode.

How many can I connect together?

Up to four in parallel and two in series, in a 4P2S or 2P4S layout. That scales the bank from 1.28kWh to 10.24kWh at 12V.

Can they charge in freezing weather?

No. Low-temperature protection stops charging below freezing to protect the cells. Discharging still works, but warm the battery before charging in winter.

Two 12V 100Ah LiFePO4 batteries. Check the listing for terminal bolts and any cable or charger, since those are not part of the battery spec.

Do I need a special charger?

Yes. Use a charger with a LiFePO4 setting, typically 14.4 to 14.6V absorption. A standard lead-acid charger will not fully charge them and can shorten life.

Our take on the ECO-WORTHY (2 pack) 12V 100Ah LiFePO4 Lithium Batteries

This is a two-pack of ECO-WORTHY's 12V 100Ah LiFePO4 batteries, each with a 100A BMS, Bluetooth 5.1 monitoring and low-temperature charge protection. They fit Group 24 boxes and weigh about 23 lbs each, so they drop into many RV, trolling motor and off-grid setups. The pair can be wired in series or parallel up to a 4P2S / 2P4S bank, scaling from 1.28kWh to 10.24kWh. At $219.99 for both at Eco-worthy as of November 5, 2026, that is the only new price listed and works out to roughly $110 per battery.
