How do I charge a lithium battery?

DALITHIUM Lithium batteries perform best when charged by a lithium compatible charger. Lead acid or SLA chargers, on-board chargers for AGM batteries, or other non-lithium chargers will charge a DALITHIUM Lithium battery but only to 70-80% of capacity. This is because DALITHIUM Iron Phosphate (LiFePO4) technology charges and charges at a higher voltage than conventional batteries (DALITHIUM lithium batteries charge at 14.4 volts). A charger that has a lithium battery setting or is designed for lithium will charge at the proper voltage.


DALITHIUM Lithium Batteries are UN38.3 certified and made from Grade A cells. DALITHIUM Lithium’s batteries are UL1642 certified and tested according to IEC62133 standards. Certified by the United Nations Manual of Tests and Standards, it complies with all international air, road, sea and rail transport regulations. Some battery models are ISO certified to ISO 9001:2008 Quality Management System and ISO 14001:2004 Environmental Management System for industrial applications. We can provide IEC62133 certification and additional laboratory services upon request of OEM customers.

What batteries do I need for my RV or camper?

The industry standard household battery size used in most RVs, campers and Van construction is the DALITHIUM 100Ah battery. This is an alternative to AGM and most lead acid batteries. If you are charging from your engine’s alternator, we recommend a DC-DC smart charger. If charging with a solar panel, we recommend the Smart Solar Charge Controller, or the Lithium setting if you have a Solar Charge Controller. A handy size chart of the number of batteries required by RV size is available here.

Are lithium batteries safe?

DALITHIUM lithium batteries are 100% safe and reliable. Our signature chemical, Lithium Iron Phosphate (LiFePO4), contains no rare earth elements such as cobalt or heavy metals, is non-toxic, contains no lead or acids, is non-corrosive, emits no gas, requires no watering or maintenance, and can be placed in any orientation , not explode or catch fire like other lithium batteries. In addition, each DALITHIUM lithium battery is protected from overheating, overcharging and short circuits by a battery management system (BMS) microchip that also prolongs its lifespan and is housed in a tough waterproof case (Although enough water can conduct electricity between the terminals, so don’t submerge the battery).We recommend to use a LiFePO4 charger to achieve the best reliability and performance.

How do I figure out when the battery is fully charged?

The LED on the DALITHIUM lithium battery charger will change from red to green.

For all DALITHIUM lithium batteries, we recommend using a LiFePO4 charger. A 12v SLA charger will work, but will only partially charge the battery, reducing performance and lifespan.

How to make the battery life of lithium iron phosphate battery the longest?

LiFePO4 batteries should be “charged” after each use. For longest life, we recommend not fully discharging the battery, nor overcharging the battery after its full charge cycle by connecting it to a charger. Remember that there is a finite number of charge and discharge cycles a battery can have in the long run, and that “one cycle” is a complete charge and discharge cycle, or the sum of the two to make a complete cycle.

How should I store the battery?

Store the DALITHIUM lithium battery in a cool and dry place and make sure it is fully charged before storing. For long-term storage, we recommend recharging them on a regular basis – usually a monthly or three-month “full charge”.

I Need a 24 Volt Battery, Can I Use Two 12 Volts Instead?

Yes! Multiple batteries to be connected together to produce a higher voltage is called series connection. Our 12V batteries can be connected in series up to a maximum of 48V. For more information on batteries connection in series or in parallel, detail the two processes here.

Batteries connection in series is a common practice in the boating and solar storage fields. For example, some of the professional bass fishing matches we sponsored run their trolling motors on two Lithium 12 Volt DALithium batteries connected in series. It provides the high voltage needed for larger motors while delivering the long amps needed to run a trolling motor all day.

What is your warranty policy?

We offer a 5-year warranty on all battery packs. We ensure that the LiFePO4 battery pack has at least 5,000 cycle life @ 80% DOD, which means that after 5000 cycles, there will still be about 80% capacity remaining. Normal charge and discharge once a day, at least 10 years design life of use.

How do you control the quality?

We have ISO9001 certification, and there are corresponding QC controls from incoming materials to production to shipment. The battery pack will undergo a cell test before assembly, and the battery pack will undergo an aging test before leaving the factory, and it can only be shipped after it is confirmed to be our normal standard.

Are lithium batteries suitable for marine use?

Yes, lithium batteries are safe for boat&marine applications. Lithium batteries are designed to be sealed, which means moisture or even a little water splashed will do no harm on it. Besides, most lithium batteries have an integrated battery management system (BMS).

Will lithium batteries make my boat faster?

One of the easiest ways to increase fuel efficiency is to reduce the weight of the boat. With a lightweight lithium battery, you don’t have to sacrifice much gear for better fuel economy. A heavy lead-acid battery will only slow your boat down by comparison.

How do you provide warranty?

Please check the attached warranty. During the warranty period, under the condition of correct use, if there is any problem, we will provide new accessories and guide the replacement for free. If further feedback still unable to be repaired, we will replace the new products free of charge, but the defected products must be kept at your place, our engineers will go to help you check and repair.

Can I Charge A Lithium Battery With An AGM Charger?

A lithium battery should be charged by a lithium charger wherever possible, but there are also other options. The nominal charge voltage for an AGM battery is 14.1-14.4V, which means that using a lead acid battery charger set to use the AGM setting will work correctly in most cases.

Are Lithium Ion Batteries Deep Cycle?

All lithium-ion cells are deep cycle featured and they are qualified to be fully charged and discharged. There will be a significantly life increase of the battery if the depth of each discharge while limited to 80% of the rated capacity.

How long will a 100Ah Lithium battery power a Trolling Motor?

A 12-volt 100Ah lead acid deep cycled battery could run a 30lbs trolling motor on Speed 4 setting for around 4 hrs.

RV batteries compare to Car batteries – Any differences?

First of all, there are several battery types. The battery used to start and run the engine is referred to as a cranking battery or a chassis battery. This battery is not suitable to power your appliances. The batteries which widely used to support 12 volts to the RV are called RV household batteries.

How to install an RV battery?

To install an RV battery, first turn off everything that draws power from the battery, including small appliances like overhead lights. Make a note of where the current battery is, then disconnect the cables – first the negative, then the positive. If necessary, clean the cable and the terminals of the new battery, then insert the battery and reconnect the cable. Install any securing hardware that came with the battery, and give it a test run!

Can I use the battery to start a car?

This batterys is not suitable for cars cranking use.
