Frequently Asked Question

No, our batteries have over discharge protection. What this means is that once the battery reaches 10v it switches off to protect itself.
Yes, our LiFePO4 batteries can be connected in series and parallel up to 4 batteries.
No, the LiFePO4 has protection which prevents you damaging it with a high voltage charge. However no more than 70V DC output charger, normally these chargers are 14.6V, 29.2V, 58.4V, while we set the BMS Withstand Volts 70V.
Our LiFePO4 have a life cycle of at least 10 years. We expect due to usage variances that they can last between 10 to 12 years.
No, the LiFEPO4 is a storage battery only, it does not have Cold Cranking Amps required for vehicle engine starting.
Our Batteries are commonly used for off grid, marine, RV and golf cart applications. You can use our lithium batteries for any application that would normally use a single or multiple lead acid, GEL or AGM batteries.
Our lithium has about twice the useable capacity as a Lead Acid or AGM battery. The available amps (time) is almost identical to these options however, it is more cost efficient and about ¼ the weight. Refer to the product pages for dimensions or get in touch with our team for more information.

Our LiFePO4 batteries are sealed. They can be put into locations that might get wet or damp without worry about damaging the battery.

No, it is safer than Lead Acid/AGM. Our LiFePO4 Lithium Batteries have built in protection circuits. This prevents a short circuit and has under/over voltage protection, a feature which most Lead Acid or AGM do not.

Our LiFePO4 Lithium batteries are sealed, they do not release any liquids or harsh fumes.
Our LiFePo4 batteries are safe, non-flammable and non-hazardous by international and federally regulated standards.
Our internal battery protection system is an innovative design made to protect the lithium cells.
Internal Features:
  • Low Voltage Protection Switch – Automatically disconnects at 8V
  • Over Voltage Protection Switch – Automatically disconnects at 15.6V
  • Short Circuit Protection Switch – Automatically disconnects
  • Reverse Polarity Protection Switch – Automatically disconnects
  • Internal cell balancing – Automatically balances cells
  • Charge Balancing – Independent balancing for multiple batteries connected in parallel or in series.
Anything over 8v is considered full. When the battery is fully charged, the volts could be 14.5-14.6V while connected to the power source. Once removed you may see a drop in the volts to around 13.8-14V due to no connected reserve.

For a more accurate calculation of battery currents divide load watts by actual battery voltage, this will be in the range 12-14V (24-28V).

Then to allow for inverter efficiency, typically 85%, divide the figure by 0.85. Thus:

For a 300W load at 12V….300 ÷ 12 ÷ 0.85 = 29.4 Amps.

For a 300W load at 14V….300 ÷ 14 ÷ 0.85 = 25.2 Amps.

Similarly:

For a 300W load at 24V….300 ÷ 24 ÷ 0.85 = 14.7 Amps.

For a 300W load at 28V….300 ÷ 28 ÷ 0.85 = 12.6 Amps.

Note: Figures in brackets are for 24V systems.

Yes, the battery can be charged from standard commercial solar modules, it will require a solar charge controller.
