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.

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).
