FAQS

How do I charge a lithium battery?

TYKOOL Lithium LiFePO4 batteries perform best when charged by a LiFePO4-compatible battery charger. LiFePO4 batteries require a different charging profile and voltage requirements compared to traditional battery chargers. Chargers designed for different chemistries may work, but they may not charge a TYKOOL Lithium battery to full capacity. It’s important to select a charger that has a LiFePO4-compatible constant-current constant-voltage (CC/CV) charging profile, provides the correct charging voltage for your battery, does not exceed the charge current (amp) for the battery, and has a charge indicator LED to let you know when the battery is fully charged. If you need help finding a compatible charger for your TYKOOL Lithium battery, or if you want to check your current charger compatibility, please reach out to our support team.
What vehicles/devices are these batteries compatible with?

Our 12V lithium phosphate (LiFePO4) batteries are designed to start a wide range of 12-volt systems, including:

- Motorcycles (Scooters,cruisers, sport bikes, dirt bikes)

- ATVs/UTVs (all-terrain vehicles)

- Boats/PWC (personal watercraft, jet skis)

- Snowmobiles

- Lawn mowers, tractors, and riding lawn equipment

Check your owner’s manual or contact us to confirm sizing and terminal type for your specific model.
Will this battery fit my vehicle?

We provide detailed sizing charts (length x width x height) and terminal type (top-post, side-post, etc.) in the product description. If unsure, message us with your vehicle’s make/model/year, and we’ll confirm compatibility.
Can I use my existing lead-acid battery charger?

Yes, but we recommend a LiFePO4-specific charger for optimal performance. Standard lead-acid chargers may work if they have a float mode (<14.6V). Avoid chargers with “equalization” modes, as they can damage LiFePO4 batteries.
Is Tykool battery available to use in my e-bike?

We are sorry, No. Currently we do not supply lithium type motive battery for electric vehicles like electric bikes,tricycles and cars.
Is a higher charging current safe for lithium batteries?

Yes, as long as it stays within safe limits. A charging current below 50% of the battery capacity is optimal, and any current not exceeding the battery’s rated capacity is safe. Lower current increases safety but takes longer, while higher current (within limits) reduces charging time.

Are Lithium Batteries Safe?

TYKOOL Lithium batteries are 100% safe & reliable. Our signature chemistry, Lithium Iron Phosphate (LiFePO4), does not contain rare earth elements (like Cobalt) or heavy metals, is non-toxic, including no lead or acid, is non-corrosive, does not off gas, requires no watering or maintenance, can be placed in any orientation, and unlike other lithium batteries will not explode or catch fire. In addition, each TYKOOL Lithium battery is protected from over heating, over charging, and short circuiting, by a battery management system (BMS) microchip that also extends the lifespan and is contained in a rugged, waterproof case (although enough water can conduct electricity between the terminals, so don’t submerse the battery). For best performance & reliability we recommend using a LiFePO4 charger.
Why choose LiFePO4 over traditional lead-acid batteries?

- Lightweight: Up to 70% lighter than lead-acid batteries, reducing vehicle weight.

- Longer lifespan: 5-10x more cycles (2,000+ cycles at 80% depth of discharge).

- Faster charging: Charges 3x faster than lead-acid.

- Zero maintenance: No water refilling or acid leaks.

- Reliable starts: Stable power output even in low temperatures.
Does this battery include a built-in BMS (Battery Management System)?

Yes! All our batteries feature an advanced BMS for:

- Overcharge/discharge protection

- Short-circuit prevention

- Over current protection

- Cell balancing for maximum safety and longevity.
Can this battery handle cold weather?

Yes! Our batteries operate in temperatures from -4°F to 140°F (-20°C to 60°C). Unlike lead-acid, LiFePO4 delivers consistent cranking power in freezing conditions (ideal for snowmobiles).
How do I choose the right charger current for my 12V lithium battery?

Charger selection depends on battery capacity. A 12V 1A charger works with all capacities and offers the highest safety. A 12V 2A charger is suitable for batteries up to 4Ah, while a 12V 3A charger is recommended for batteries 5Ah and above for faster charging within a safe range.

It would be interesting to have the front dimensions to ensure the space required for installation. This battery is very small in comparison to an acid battery. The arrangement of the poles requires us to make changes in order to install it correctly.

maintains and holds it power. Love the voltage button to check condition. It's great, good upgrade.

I bought this for my 2015 Aprilia Tuono1000 and it fit perfectly came fully charged was very light built solid and had a digital readout on top that was a nice touch I couldn't find a nicer lithium battery on Amazon for the price and it came really quick fired up the bike even though I had a bad stator by the time I got the bike parked the battery was totally gone but after replacing the stator next morning and not charging the battery not even looking at what it read on the meter it fired right up nice recovery and after 2 days of rides not one problem firing up so so far five stars atta boy guys

Exactly as described! Fits perfect and the LCD display is legit!

2024 / 05 / 30

Surprisingly it still has a full charge even though I've used it on my riding mower to start about 6 times already. So light weight it's ridiculous feels like a fake. but the startup is instant no struggle at all. wish they weren't so expensive but if it lasts it is totally worth it. Seems like I had to buy a new acid battery every year. Love it bought 3 more for my scooters.

Mark Lybarger

2024 / 05 / 26

i installed this battery in my burgman 2014 an400. previously, i had gel agm battery installed and it just didn't cut it. my bike will stall out if i haven't ridden it much lately, and i need a dependable battery to restart. this does that amazingly. love this battery.

Q Will this battery fit my 2018 Polaris 450 ho Quadrunner or what of your batteries might fit my Quadrunner: A
Dear Daniel, Thank you for reaching out to us with your inquiry. We sincerely apologize, but after searching our database, we were unable to find an exact match for the model "2018 Polaris 450 ho Quadrunner." Based on our research, it is highly likely that this vehicle is now officially referred to as the 2018 Polaris Sportsman 450 HO. The name "Quadrunner" was historically used by Polaris and is still commonly used by enthusiasts, but the official product line is now named "Sportsman." To ensure we recommend the correct battery for you, could you please double-check the model name on your ATV's frame or owner's manual? Alternatively, providing us with the model number of your current lead-acid battery would be the most accurate way for us to identify a perfect replacement. If you can confirm that your vehicle is indeed the 2018 Polaris Sportsman 450 HO, then the compatible battery from our range is the: Model: LFP14AH-BS-PRO You can click the link below to view all the details, specifications, and pricing for this battery: https://www.tykoolbattery.com/tykool-ytx14ah-bs-high-performance-lifepo4-lithium-atv-utv-scooter-battery?variant=LFP14AH-BS Thank you for your interest in our products.
