Lithium vs tubular battery

Upfront price, usable capacity, lifespan and real cost per kWh compared.

Our engineers' verdict

Lithium costs more upfront but is about 3× cheaper per kWh over its life and needs no maintenance. Choose tubular only if the budget is fixed today and you plan to upgrade within 3 years.

FAQ

Can I upgrade from tubular to lithium later?

Yes, if your inverter supports a lithium profile. Replace the whole bank at once.
