FAQs
What is an A-Grade Cell?
An A-Grade Cell refers to a battery cell that meets the highest standards of quality and performance. These cells are rigorously tested and graded based on their capacity, voltage, and overall reliability. At EcoWatt, we meticulously select only the highest quality A-Grade Cells to ensure superior cycle life, consistent performance, longer lifespan, and greater safety compared to lower-grade cells, making them the top choice for premium battery products.
How do I use the Bluetooth Monitoring Feature?
To use the Bluetooth Monitoring Feature, first download the EcoWatt Energy Connect app from the Apple App Store or Google Play Store. Then, open the app, connect to your battery, and start monitoring.
My Charger says the battery is fully charged, but the app is not showing 100% charge, why?
Sometimes, the State of Charge (SOC) display on the app may not be fully accurate until the battery has gone through a few full charge and discharge cycles. The BMS needs time to 'learn' the battery’s parameters and adjust accordingly before the Bluetooth monitoring provides precise readings.
What are your Recommended Charger/Shunt Settings?
- Charged voltage: Around 13.5V, but you can double-check this once the battery is fully charged.
- Bulk charging voltage: Between 14.4V to 14.6V
- Absorption voltage: Between 14.4V to 14.6V
- Float voltage: Around 13.5V
- Storage voltage: Similar to the charged voltage; 13.5V
- Discharge floor: It can be set above 20%. This setting is more about your personal preference for the charger than the battery. The higher this percentage, the better. We don't recommend going below 20%.
- Tail current: Anywhere between 2-4% is fine. Once the charging current drops below this range, the battery is nearly fully charged.
- Peukert exponent: This is mostly relevant for lead-acid batteries. For LiFePO4, setting it to 1.05 is standard
- Charge efficiency factor: Set this to 99%
- Current threshold: 0.1A
- Charge detection and Time to go averaging period: These can remain unchanged
- State of charge (SOC) synchronization: We recommend synchronizing the SOC to 100% once you've fully charged the battery
Can I use the EcoStore Slimline Pro 300 under the bonnet?
No, it is not recommended to use the EcoStore Slimline Pro 300 under the bonnet. We advise against using our LiFePO4 batteries for under bonnet applications due to their lower thermal tolerance compared to other battery types, such as lead-acid or AGM. The engine compartment can reach high temperatures, particularly in demanding conditions or during extended use, which can degrade the battery's performance, lifespan, and safety.

Let customers speak for us
I needed a replacement battery for my camper trailer, the EcoStore 100AH was the perfect choice. I only run a fridge, lights and an electric RTT, so that's plenty of power on tap. It was an easy fit and I can't wait to get back out bush to give it a test.
Great service, communication and product
Solid battery, well made and the BMS is idiot proof. Great product and value for money
Very impressive power. Upgraded to 3x 300AH. Now have 900AH
After much consideration l decided to purchase a Ecowatts 230 ah slimline battery. Got it for a great price. It's full of grade A cells and can charge and discharge through my 3000 watt inverter at 250amps no problem. It's very well made and has a great app.
I'm very happy that went with Ecoflow.
This product is great! Works really well and is so handy having the Bluetooth capability to easily monitor your battery.
The product has been so good to work with. So happy with the delivery and quality.
I've been looking for replacement batteries for a while to fit into the existing external chassis mount box it has made a big difference from the 100ah supplied batteries.
When I found the ecowatt with millimeters to spare I jumped at them. With the increased capacity it gave me the opportunity to install a large inverter.Happyall around
great service
I have have only used the battery so far to run an Engel whilst camping for three days in the back of the cruiser. Worked well as expected. Next job is to install it under the false floor with a DCDC charger.
Honest service, great product
Awesome to deal with. Personal phone call to make sure I was home for delivery. Was able to answer technical questions immediately.
Still building my system but is great to be able to switch the system on and off via Bluetooth.
Very happy with the battery to date.
The unit arrived promptly as well. Easy to install.
Will run my 2000Watt inverter well.
Love it- slime line and robust mounting points. Perfect for the back wall of my n80 hilux. Double Anderson outputs, and 230Ah. So far so good👌
