Frequently Asked Questions

How safe are Lithium Iron LiFePO4 Batteries?

Our BWB LiFePo4 batteries are considered to be safe, non-flammable and non-hazardous by international and federally regulated standards. It’s environmentally friendly – phosphate is not hazardous so it’s friendly to both the environment and out health. BWB LiFePO4 Batteries includes BMS (Battery Management System) which are important to: 1. Prevent damage to equipment and property. 2. Maintain safety for users. 3. Almost completely eliminate concerns about use of the wrong charger for this chemistry type. 4. Minimise the risk of over-discharging and damaging the batteries. 5. Provide short circuit and overcharge protection.

What type of Lithium Iron cells do you use for your LiFePO4 Batteries?

We use Brand New Class A prismatic cells. Available cells at the moment are 3.2V 50AH, 3.2V 100AH & 3.2V 200AH. These cells are supplied by Ganfeng Lithium, one of the Top 3 China manufacturers. In 2019, Ganfeng Lithium signed another long-term agreement to supply lithium cells for Volkswagen & BMW.

What type of BMS do you use?

We use DALY Brand BMS. Some models come with SMART BMS where you can download the SMART BMS app from any Android or Apple device. DALY BMS are the best battery management system in the market.

How does BMS protect the battery?

DALY BMS has 6 safety levels of protection: • Over-discharge • Over-charge • Over current • Short-circuit • Drop • Temperature

What can I use a Lithium Battery for?

Our BWB LiFePO4 Batteries are great upgrade to replace the commonly used deep cycle batteries like Lead Acid, GEL or AGM. Deep cycle batteries are widely used for marine, RV, 4WDs, electric vehicles, storage systems and golf cart applications. You can use our LiFePO4 batteries for any application that would normally use a single or multiple lead acid, GEL or AGM batteries.

How do I change my batteries to Lithium?

Just simply replace your old battery with our BWB LiFePO4 Battery and you may use the same cables. At the same time, you will need to make sure that your chargers are lithium compatible.

How do I charge a Lithium battery?

Use only a lithium specific charger. Our BWB LiFePO4 Battery requires constant charging. Before you use your LiFePO4 battery, please charge it up until it gets full. First time charging may take longer but succeeding charges will be faster. Note that different voltage requires different max input/charge voltage. Voltage 12V - Standard Voltage 12.8V, Max Input Voltage 14.6V, Discharge Cut-Off 10V. Voltage 24V - Standard Voltage 25.6V, Max Input Voltage 29.2V, Discharge Cut-Off 20V. Voltage 36V - Standard Voltage 38.4V, Max Input Voltage 43.8V, Discharge Cut-Off 30V. Voltage 48V - Standard Voltage 51.2V, Max Input Voltage 58.4V, Discharge Cut-Off 40V.

Charging Sources:

• Alternator: Most factory alternators can sufficiently charge our LiFePO4 Battery. You can use our Lithium Relay or a DC/DC charger with Lithium option. • Inverter: Most inverters have a battery type switch that can either be selected to AGM for the closest setting to lithium or have a custom voltage setting that can be programmed to optimize your lithium battery. • AC/DC or Solar Charger: You can set your chargers voltage to lithium. Please take note of your battery voltage type to manually set the voltage. Like for a 12V system, the max charge voltage is 14.6V.

Can I still use my LiFePO4 battery when it has gone flat?

No. The BMS cuts off the battery supply when 90% of its power has been used. When this happens, simply charge back the battery. It’s best recommended you use at least a minimum of 10A lithium charger so that it activates the BMS quicker. Always remember that BMS also protects your battery from over-discharge. Attempting to use the battery after it has cut-off may take longer time to reactivate when recharging.

How long do these LiFePO4 Battery last?

Our BWB lithium Iron LiFePO4 battery technology will provide you with up to 3000 cycles for Electric Vehicles & up to 8000 cycles for Electronic Storage Systems still provide over 80% of usable capacity.

Can I lay the battery on its side or upside down?

We don’t recommend you lay it either sideways or upside down. The lithium cells have pressure release valve which helps protects the cells when extreme pressure is happening and/or any excess of electrolytes may need released. To keep the battery safe, healthy, lasts longer and away from possible damage, keep it standing upright for maximum performance.

Where are your LiFePO4 batteries made?

We build our LiFePO4 batteries in Australia. Major battery components are sourced directly from only the best manufacturers with reputable background and experience. This means you will be buying the best quality product for your lithium battery needs.

Why do you sell cheaper compared to other sellers?

We have been in the battery business in China for more than 30 years now. We know exactly where to source all of the best quality components, from Lithium cells to BMS including cables, etc. We partner directly with the best companies in the China. No Middle Man. Therefore, it makes our BWB LiFePO4 products more affordable and high quality.
