Can I replace my Group 24 lead-acid battery with this?

Yes. It is built to BCI Group 24 size, so it drops into Group 24 lead-acid, AGM and SLA trays. Check your charger's profile for lithium before you swap.

What does the Bluetooth app show?

It shows voltage, current, capacity and cell status over Bluetooth 5.0. That lets you watch loads and charging without a separate shunt monitor.

Can I charge it in freezing weather?

Charging stops below -7°C to protect the cells, and the charge range is 0-55°C. Discharging works down to -20°C.

Can I connect several together?

Yes, it supports 4S4P expansion from 1.28kWh up to 20.48kWh. Keep the batteries matched and follow the manual for series and parallel wiring.

What charger does it need?

ECO-WORTHY recommends a 12V 10A charger, with a maximum charge voltage of 14.6V. The battery and manual are in the box; the charger is not.

How big and heavy is it?

It measures about 10.2 x 6.6 x 8.4 inches and weighs 10.5kg, with M8 terminals. That is light for a 100Ah lithium battery.
