What can I power with a 12.8V 90Ah LiFePO4 battery?

It stores about 1.15 kWh, enough for small solar setups, e-bike packs, boat electronics or a trolling motor for short trips. Larger loads need multiple batteries or a higher-capacity bank.

How does 90Ah compare with 100Ah LiFePO4 batteries?

It gives roughly 10% less capacity than a 100Ah unit but is often lighter and smaller. The trade-off is shorter runtime between charges for the same load.

Does it need a special charger?

Yes. Use a charger or solar controller with a LiFePO4 profile, typically 14.4–14.6V absorption and 13.6V float. Lead-acid chargers can shorten its life.

Can it be used in cold weather?

LiFePO4 batteries should not be charged below 0°C (32°F). Discharging in cold is fine, but charging needs the battery above freezing unless it has built-in heating, which this model does not list.

What certifications does it have?

It is listed with CE, RoHS, UN38.3 and MSDS certifications, covering safety, hazardous materials and transport testing.

What are its dimensions and weight?

It measures about 307 × 169 × 208 mm and weighs 10.2 kg. Check your battery compartment or rack against those figures before buying.
