Have everything under control with Bluetooth monitoring!
These batteries are equipped with a Bluetooth monitoring system, so you can track important data like voltage of each cell, temperature, charging current, discharging current, state of charge and many more on your mobile phone in real–time. Just download the android or iPhone app and you are ready to go.
Another advantage of this battery is that it has the low temperature disconnect. If you live in a cold place where the temperature goes often below 0 degrees Celsius the BMS will prevent charge and discharge below that temperature so that the battery will not degrade faster.

Main Advantages
More Usable Capacity
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.
Light Weight
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.
BMS Protection
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.
Low Temperature Protection
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.
Long Cycle Life
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.
Bluetooth Connectivity
You can wirelessly and quickly keep an eye on its critical data through a Bluetooth® connection. You can access this function by downloading the Bluetooth app, which is available for iOS® and Android® devices.
FAQ
Does the charger come together with the battery?
No, you have to buy the charger separately.
Can i connect the 12v batteries in series to form a 48v battery?
Yes, you can connect up to 4x 12V liFePO4 batteries, or 2x 24v in series to make a 48v battery pack. Note: 12v 50ah batteries can only be wired in parallel and cannot be connected in series.
Can i return the battery if my system does not support it?
We gladly accept returns within 30 days of receipt for most items in new condition. If an item is new, unused, and in the original packaging, we are happy to accept a return up to 30 days from the original invoice date with no restocking fee
Why LiFePO4 and not regular li-ion?
LiFePO4 batteries have a much higher cycle life of 3000+ cycles compared to 600 cycles to other li-ion batteries. Another big advantage is safety as there is no risk of explosion or fire.
Does the bms have a balancing function?
Yes, the BMS does have a balancing function and it will keep the cells balanced.
Why does the voltage drop from 14.4v to 13.6v when i stop charging it?
13.6v is the resting voltage of Lithium cells. The battery at 13.6v is still 100% charged. It is totally normal.
Does it have a Bluetooth conncection?
We also sell batteries with Bluetooth connectivity. Please check our products.
Can the battery handle high start-up current rush for older machines and devices?
Yes, it does handle high current for 3s. Please check the specifications for each battery to check the high in-rush current supported.
What kind of cells are inside your batteries?
Our batteries are built with Grade A prismatic cells. That makes the failure rate much lower than the batteries built with cylindrical cells, because we use fewer, but larger cells.
Can we use your 36v 50Ah battery to power our boat trolling motor?
Yes, it can be used for powering trolling motors. Check the specifications of our battery and the power output of your trolling motor.
I would like to replace my lead acid battery with your lithium iron phosphate battery in my vehicle. I want to use it for starting up my vehicle. Can it be used that way?
No, our batteries are not meant to start up the vehicle. The current is too high so the BMS will cut it off to protect the battery.

Quick shipping, battery charges exceptionally fast, and the manufacturer claims a lifespan of around 10 years. We’ll put it to the test. Excellent value for the price.
