FAQs
Everyone has questions, we have the answers. We love to help. If you need answers not covered here, contact us for fast customer support.
How do I charge LiFeBlue Battery?
LiFeBlue Battery BMS is unique. It is designed to charge with any kind of charger that can provide 14 Volts up to 14.6 Volts. You do not necessarily need a Lithium battery charger. Use a converter, Inverter charger, alternator direct, or PV solar power.
Some converters may charge slowly if designed for lead acid batteries. You can charge using 5 Amps up to the specified maximum. It is important to regularly fully charge above 14.2V so the SoC meter is recalibrated and the cells to remain in balance.
Can I use my alternator to charge the battery?
Yes, alternator charging is very beneficial. Our BMS will begin charging with voltage as low as 13.6 Volts. With proper wire size, no DC converter or special regulator is needed! While driving, you can choose when the alternator is charging. The Alternator and Inverter combination can take the place of a fuel generator saving many hundreds of dollars, extra weight and wasted space. You can request a wiring diagram showing our recommended method to connect your alternator.
Can I use Solar Power to charge LiFeBlue Battery?
Yes, a PV solar power system is a great way to charge. All PV solar controllers work with LiFeBlue Battery. Do not use temperature compensation for charging.
What size and how many batteries should I buy?
All li-ion batteries have current limits imposed by the BMS. You must not exceed the specified current or the battery will turn off in protection mode. By placing batteries in parallel, you increase current capability. You should also consider how mach battery capacity you need to not run out of energy before your next charge period. At any time in the future, you can add additional capacity to your parallel battery bank.
How long will my battery last?
LiFeBlue Battery has been designed for best cycle life possible. It can can easily last for several thousand cycles depending on use and care. Keeping the battery cool will provide the longest life.
Can I use LiFeBlue Battery to start my marine or RV generator or engine?
LiFeBlue Battery is designed for deep cycle use. However, our new ULTIMUS models have a special BMS to allow high current to pass for engine starting.
