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 300 under the bonnet?
No, it is not recommended to use the EcoStore 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.

Accessories Compatibility/Recommendations
1. AC-DC Chargers / Inverter-Chargers
These devices allow your system to draw from AC mains (shore power, generator, grid) and convert to DC to charge your batteries
Recommended Models:
Victron MultiPlus / MultiPlus II inverter/charger series
Victron Blue Smart series
support custom charging profiles for lithium (LiFePO4) and allow easy monitoring and updates via the VictronConnect app.
2. DC-DC Converters / Chargers
DC-DC chargers are used mainly when you want to safely charge your battery bank from another DC source (for instance, from an alternator).
Recommended Models:
Victron Orion‑Tr Smart Series DC‑DC Charger
Victron Orion‑XS Series DC‑DC Charger
These are excellent if you have a “start battery + house battery” separation
3. MPPT (Maximum Power Point Tracking) Solar Charge Controllers
MPPT controllers extract the maximum power from solar PV panels, converting varying panel voltages into optimal charging currents for the battery.
Recommended Models:
Victron SmartSolar MPPT Series - Bluetooth Compatible
Victron BlueSolar MPPT Series - Need Separate Bluetooth Dongle.
4. Shunt / Battery Monitoring
A shunt-based battery monitor can be used to measure state-of-charge, energy used, and input/output flows.
Recommended Model:
Victron SmartShunt - small, accurate, Bluetooth-enabled
Not on this list?
Any lithium-compatible accessory from brands like Enerdrive, Redarc, Renogy, Itechworld, or Kickass Products will also work just fine as well.

Let customers speak for us
A fantastic battery, that fits well under the false floor of my Toyota landcruiser 300.
Great quality, Bluetooth function works great
Recently purchased but a quality product so far. It really has changed camping off grid for me. I just returned from a week camping and when everyone else is starting cars and running generators to keep their gear running she has a load of storage and is easily topped up with solar. The BMS and app are awesome, super easy to see what's going on. Happily recommend.
Looks good and performs great to how need it to.Highlyrecomended
Needed a battery for our new caravan and this was the perfect solution. Great transaction and quality product.
Quality product, fast delivery, highly recommend.
Great battery, good quality and fit perfect!
What an amazing battery. We originally purchased one for our 4wd for extended weekend camping. It performed so well, we purchased another two for our camper. We have now just returned from a 2 week adventure and for the first times in years we didnt have low battery anxiety. I highly recomend these batteries for performance and ease of monitoring via the blue tooth app.
This is the second 230ah slim battery I’ve bought from Ecostore, great battery fits under the floor of a Y62 nicely. Definitely be using more of these.
Great product ..Have only just installed in my Ute so haven't got any long term testing but so far everything looks and works as it should. Well built and solid, no rattles or anything loose like some batteries ive seen..Bluetooth comes in handy with the app to make sure everything is charging and working right with my set up.
Good product and super fast delivery
Great battery build quality, high function BMS, included all fasteners
In today’s market you don’t always find a product that supports it reputation.
Ecowatt is a product that fully supports the great reviews and professional recommendations.
I replaced our batteries with two 200Ah batteries and set out on a trip around Flinders Ranges and Lake Eyre, they never missed a beat.
Will be purchasing a third to give me 600Ah when we get back.
Put 2 x 200amp batteries outside the caravan on the chassis. Working 100% as hoped. Will buy again when the camper battery needs replacing. Very happy with the product and service! 6 stars!
Fast delivery. Well packed. Charging well up to 105 ah off my dc dc charger. Great app.
Easy purchase. Timely delivery. Quality product
Customer Reviews
Great quality, Bluetooth function works great
From start to finish of buying, receiving and installing the battery everything has gone smoothly. We are yet to give the battery a good test run as we are not planning on travelling in the van for a few months, but it’s working great and having the app is a real bonus.
Quality product, fast delivery, highly recommend.

Ecowatt 300Ah batteries are fantastic as they are compact and allowed me to replace 8 x 100Ah lead acid batteries with 6 x 300Ah Ecowatt lithium batteries. Going from 800Ah to 1800Ah that will allow us to enjoy our time on the houseboat without worrying about losing power of an evening after overcast days. Looking forward to making the most of our new found power source.
