What is a BMS? What does it do and where is it located?
How long will it take to charge a lithium battery?
How deep can a lithium iron phosphate battery be discharged?
How can I determine the state of charge (SOC) of my lithium iron phosphate battery?
Can I use my existing lead-acid battery charger (Wet, AGM or Gel) to charge SRP lithium iron phosphate batteries?
Will a 12V, 100Ah lithium iron phosphate battery give a longer run time than a 12V, 100Ah lead-acid battery under the same conditions?
BMS stands for Battery Management System. The BMS protects the cells from getting damaged — most commonly from over or under-voltage, over current, high temperature or external short-circuiting. The BMS will shut off the battery to protect the cells from unsafe operating conditions. All RELiON batteries have a built-in BMS to manage and protect them against these types of issues.
We recommend using a rate that charges our batteries in 2-5 hours. Please refer to the data sheet for your particular model, to find the recommended charge rates. All of our data sheets are available on our website within the product section.
LiFePO4 batteries can be discharged up to 100% without risk of damage. Make sure you charge your battery immediately after discharge. We recommend discharging be limited to 80-90% depth of discharge (DOD) to avoid the BMS disconnecting the battery.
The best way to determine the SOC of your battery is to use a battery indicator— a high-precision instrument that captures instantaneous and integrated data in real-time. We have Victron Fuel Gauges available for purchase on our product page.
We do not recommend the use of a flooded charge profile with our batteries. These chargers may reach the over voltage protection limit and disconnect. It won’t damage the battery but will likely result in charger faults. Before using any charger with SRP batteries it is best to first verify the charge profile is within our specifications, which can be found in our Charging Instructions. Be sure to read over our charging guide in detail prior to charging your SRP battery.
Yes. Lithium iron phosphate batteries provide more useable capacity than a lead-acid equivalently rated product. You can expect up to twice as much runtime
