Sealed lead-acid batteries can only supply 50% of the available energy, while lithium LiFePO4 batteries can supply up to 100%. That means you can fully discharge the battery and cycle it thousands of times.

Not only are elker batteries 3 times lighter than traditional lead-acid batteries with the same capacity, but they also require no maintenance whatsoever. You can just install them and forget about them. An additional carrying strap is provided that will make it easy to carry it around.

All of our Bluetooth batteries have an integrated Battery Management System that protects the battery from overcharging, discharging, low temperature and over current. It also has a balance function that will keep the cells inside balanced and in good condition.

It is not recommended to charge Lifepo4 batteries at temperatures below 0 degrees Celsius. So if you live in a cold environment you can set the charging parameters in the Bluetooth app to stop charging the battery at any temperature you want.

More than 3000 cycles at a depth of discharge of 100%, 3,500 cycles at 80% and 5,500 cycles at 50%. The recommended DOD is 80%. All of our LiFePO4 batteries are backed up with Elker’s 3-year warranty.

Elker 24v Lithium Batteries can be wired in series of 2 to create 48v power bank. Up to 16 batteries can be wired in parallel to achieve a higher capacity.
