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.

Nice and light weight. Easy to install.

Abhinav

2026 / 03 / 15

Basically, if you’re looking for a lithium battery for your Royal Enfield Himalayan 411 and aren't sure about the fitment, I can confirm this TYKOOL YTX9-BS-PRO fits perfectly. No modifications or ""creative engineering"" required to get it into the tray. The installation was actually easier than the OEM/factory battery. It’s much less of a struggle to drop in and get the terminals aligned compared to the stock unit. The biggest win here is the weight difference. This thing is significantly lighter than the stock lead-acid brick, which is a huge plus for keeping the bike's center of gravity manageable. It cranks the 411 over instantly with zero hesitation. This is my initial review, I’ll be sure to update this in about 6 months to report on the long-term reliability. But for now, it's a solid upgrade.

Client satisfaite

2025 / 01 / 12

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.

Rusty

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

Efrén Herrera

I have a 11 year old 400cc motorcycle and I live at high altitude. With this battery I can finally start my bike at first try. I really recommend it.

This things unbelievable, I took it out of the box. I said to myself no way,I was wrong very light and powerful. Buy one u won't be disappointed.

Jaime Ralph Valeron

2024 / 06 / 19

The battery worked right out of the box, cranks easily and fast every time. And it's very light. I hope it also has good longevity.

Brian Nugent

2024 / 06 / 07

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

Zach

2024 / 06 / 05

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

W. J. Dougherty

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.
