Battery Size Calculator

Calculate Your Exact Power Needs. Planning a campervan conversion, marine upgrade, or off-grid system? Don't leave your energy storage to chance. Use our engineering-grade calculators below to determine exactly how much lithium capacity you need to run your appliances, how long your battery will last, and which Titan model fits your lifestyle.

Tip: We always recommend adding a 20% buffer to your final calculation to account for unexpected power usage or cold weather performance.

Battery Capacity Calculator - simple & fast

Enter the battery volage and Ah rating (found in the table below) of your chosen battery, then tap the 'other battery parameters' dropdown and enter your discharge current to see how long each battery will last.

Battery Life Calculator - detailed with sleep modes & wattages

Enter the chosen battery capacity (use Ah) and set the discharge safety to 0%. Enter sleep/awake mode time as applicable, and then your current draw or wattage of your device(s) - this can be found on the back of most appliances. Remember - watts are the same in DC and AC draws.

Battery Size Calculator - will show how much capacity you need based on energy demands

Enter your application load in watts (total of your system), select lithium-ion and use the battery voltage of your chosen battery (in table below), then how long you need your system to be powerd for, and if you wish to add in a buffer (remaining charge).
