Q: What is the most ideal approach to store Lithium-Ion batteries?
A: Lithium-particle batteries can hold a charge for a long time. It is ideal to store a lithium-particle battery with a fractional or full charge. Sporadically, a lithium-particle battery with a low charge is put away for an extensive stretch of time and its voltage gradually drops to underneath the level at which its inherent security system permits it to be charged once more.
In the event that the battery will be put away for a while, it’s a smart thought to take it out and re-energize it following a couple of months. Even better is really utilizing the battery at regular intervals and afterward, leave it mostly or completely energized.
Q:How can I charge my lithium batteries?
A: Our lithium-particle innovation utilizes the most recent and most exceptional implicit battery assurance framework to forestall harm to the battery. You may use a standard charger for our items, albeit now and again a lithium charger might be needed to charge the batteries.
- Alternator: Most processing plant alternators will adequately charge our lithium batteries and don’t need any changes.
- Inverter: Most inverters have a battery-type switch that can either be chosen to AGM for the nearest setting to lithium or have a custom voltage setting that can be modified to enhance your lithium battery.
- Inverter/Charger: You can set your inverter charger’s voltage to charge mass and retain somewhere in the range of 14.4V and 14.6V. The buoy ought to be set to 13.6V.
- Standard Charger: Our battery’s interior BMS permits you to utilize a standard battery charger, at times a standard charger may not completely charge our lithium battery and you may have to buy a lithium charger to get the full usable limit from it.

Q: What is a BMS? What does it do and where is it located?
A : BMS stands for Battery Management System, it works to protecting the cells from getting damaged against 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 Polinovel batteries have a built-in BMS, that are not visible for customers at most of time, to manage and protect battery against these types of issues.
Q: How deep can a lithium iron phosphate battery be discharged?
A : LiFePO4 batteries can be discharged up to 100% without risk of damage. Make sure you are charge your battery immediately after discharge. We recommend discharging battery to 80-90% depth of discharge (DOD) to avoid the BMS disconnecting the battery.
Q: How does the rate of discharge effect capacity?
A : The discharge rate of the LiFePO4 battery has no effect on the delivered capacity. This is not the case with lead-acid batteries, which capacity decreases significantly as the discharge rates increases.
Q: Can I mount the battery in horizontal or other position?
A : Yes, you can mount your lifepo4 battery in any position, because there is no acid inside of lifepo4 battery, and the small amount of liquid electrolyte is contained and sealed within cell. This gives you more flexibility to install the battery in the place where is best suited for your application.
Q: What’s the difference between series and parallel connections?
A : Series connections involve connecting 2 or more batteries together to increase the voltage of the battery bank. Parallel connections involve connecting 2 or more batteries together to increase the capacity of the battery bank. For example, if you connect 2 x 12V 100Ah batteries in series, the battery system will be 24V 100Ah. If you connect 2 x 12V 100Ah batteries in parallel, the battery system will be 12V 200Ah. Please feel free contact Polinovel for assistance if you have query about the connection.
Q: How can I determine the SOC (state of charge) of my lithium iron phosphate battery?
A : 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. Polinovel HDN series LiFePO4 batteries have embedded indicator that can accurately measure the discharge currents and calculates the Ampere hours flowing in and out of the battery.
Q: Is it truly obvious that we can move away while never utilizing a 230V connects?
A: Indeed, it is. However long you can watch out for your power utilization and you can run your vehicle’s motor when essential; a lithium battery will empower you to do all that you could do on the off chance that you were on connect.
Q: What are the charging voltages for lithium batteries and how significant would they say they are?
A: To accomplish the most extreme execution and helpful life, it’s fundamental that a lithium battery is charged accurately. The charging necessities of lithium batteries are totally different from those of lead-corrosive batteries. Various batteries need various voltages in any case, when in doubt, a LiFePO4 battery ought to be charged at a steady voltage of close to 14.6V. Charging at a lower voltage will do no damage except for charging over this should be kept away from by utilizing appropriate charging gear.
Q: Can I go with my vehicle alternator that I have at present?
A: Practically any 12V alternator evaluated at 120 Amps or more will charge a lithium battery productively as long as the yield is somewhere in the range of 13.8V and 14.6V. At lower voltages, the battery won’t arrive at 100% condition of charge yet it will be near the point that it’s likely not worth stressing over. Charging at a lower voltage can likewise assist with expanding a lithium battery’s helpful life.
Q: I have a solar panel at home. Is it possible to use my solar panel with a lithium battery?
A: Indeed, however, it’s fundamental to ensure that the voltage controller is appropriate. Similarly, as with the Votronic range, it ought to have a setting for LiFePO4 and this is the thing that we would consistently suggest for the greatest proficiency and long valuable life. It’s excessive and not a smart thought to keep a lithium battery continually on charge. Your provider or installer will actually want to prompt further.
Q:Do I need to provide 230V charges for lithium batteries?
A: If you want to keep your lithium battery charged, having a special LiFePO4 charger should be the best way to move. Yes, it is faster and safer as well. Sometimes, it is seen that many vehicles including your caravan, motorhome, and boat has already a charging system. In this case, you should not change the charging system. Instead, you can use the same existing charging system to charge your lithium ion batteries.
You have to take a close look if those vehicles get connected to the main hook-up. If it is so, you should disconnect it when you see that the lithium ion batteries are fully charged. There are other precautions you should follow. If you see the temperature is below 0 degrees Centigrade, you should not charge or keep the lithium batteries charging.
Q:Are lithium batteries affected by the variation of environmental temperature?
A: Yes, the performance of lithium and lead acid batteries is affected by the environmental temperature. If you have lead-acid LiFePO4 battery, you should be careful because temperature affects its charge. On the other hand, the charging and discharging process of any lithium batteries show variation in different temperature mode.
You know that the charging of lithium batteries should be between 0 degrees centigrade to +45 degrees centigrade. Conversely, while discharging, lithium batteries perform well in between -20 degree centigrade and +60 degree centigrade. So, you should be very careful when the temperature will go down as low as 0 degrees centigrade. In this circumstance, you should not charge your lithium ion batteries from a solar panel, mains hook-up, and the engine. Using a temperature sensor can keep your lithium battery protected.
Q:Is it true that there are different types of LiFePO4 batteries? If so, what are they?
A: LiFePO4 cells are of two kinds: barrel-shaped and kaleidoscopic. Kaleidoscopic cells are level and rectangular and can have a higher energy thickness which essentially implies more energy in a more modest space. Tube-shaped cells may, in principle, last longer yet the manner by which a battery is utilized more affects its cycle life. In actuality, the functional contrasts among barrel-shaped and kaleidoscopic cells are not worth stressing over.
Q:Can lithium batteries be used in caravan?
A: Of course, you can use lithium batteries in your caravan. Lithium batteries provide a longer lifespan and low self-discharge. Not only that, lithium batteries are lightweight, smaller in size but come with higher capability. So, you can use lithium batteries in your caravan without any issue.
Q:Is LiFePO4 more perilous than lead-corrosive/AGM?
A: No, it’s more secured than lead-corrosive/AGM. This forestalls a short out and has under/over-voltage security. Lead/AGM doesn’t, and overwhelmed lead-corrosive contains sulfuric corrosive that can spill and mischief you, the climate, and your hardware. Lithium batteries are closed and have no fluids and give no gasses.
Q: Shouldn’t something be said about wet/moist areas?
A: Lithium batteries are fixed however are not waterproof to areas that may get wet or sodden. It is energetically prescribed to put all lithium-particle batteries in a dry lockbox to forestall any water harm. These batteries are scarcely water-safe; notwithstanding, avoiding potential risk will expand the life span of the battery.
Q: What is the future of the battery?
A: Lithium batteries can be utilized for 3000-5000 life cycles. Contingent upon use this can be 10 years or more. A Lead-corrosive and AGM get around 300-500 life cycles before their ability is diminished significantly. Subsequently, despite the fact that there is a more forthright expense with a lithium Battery, the overhaul saves you a ton of cash after some time.
Q: Shouldn’t something be said about these dissolving lithium cell and PC batteries I saw on the news?
A: There have been not very many of these according to the number of mobile phone PCs there are on the planet. Issues have been with the “pocket” style kaleidoscopic cell configuration, have a more secure cell plan, and have a high-level BMS framework for additional assurance.
