I primarily use this battery as the core of a small, portable backup power pack to power essential field equipment. It will be a versatile power source option.
Everything went smoothly; the battery packaging was intact and undamaged, the terminal protective caps were all present, and there was no damage whatsoever. All components were clean, secure, and neatly arranged.
Best ATV battery I have ever purchased by far.
I've had this battery installed on my ATV for about a month now. So far so good, starts easily, and the engine runs fast.
The shipping was fast and the product is fully functional. I have only been using it for a month so I cannot comment on its long-term effects.
The battery is small and lightweight, yet packs such a powerful punch. The built-in BMS is also a great design. High quality and well-made.
Good size. Ships with enough power to start the motorcycle and includes terminal adapters for proper wiring connections.
It has a digital display, which comes in handy when starting the scooter, showing the battery level.
I purchased this battery to have installed on my 2014 BMW 1200 RT.The installer was unable to install it because the battery was off by 3/4 in. It will not fit in the battery box. I'm not there to see it but I am wondering if the incorrect batteryvwas sent.Regards Paul Hawgood
Dear Paul, We have responded to your email sent from another address. As stated in our previous correspondence, after verification, we confirmed that the correct model LFP20L-BS-STD was shipped according to the order specifications. Based on the vehicle model information you provided, we believe it is possible that your friend purchased the incorrect battery model. Please continue to communicate with us via our after-sales service email for further details. Please accept our sincere apologies once again for the inconvenience you’ve experienced. With deepest regards, Amy Aftersale service @TYKOOL Battery
I have a LFP20L-BS-STD battery and was wondering if why nothing happens when I click the power button on the digital screen? Is this normal or did I buy a dead battery? Also can it be charged and still ok if it is dead?
Dear Caleb, We sincerely apologize for the inconvenience and frustration this has caused you. Your experience falls far below the standard of quality we strive to deliver, and we deeply regret any disruption this may have caused. -- 1. Please provide your order number for our enquiry. -- 2. To address your question, this is not a normal situation—the power button on the digital screen should respond when pressed. The good news is that even if the battery is completely drained, it can typically be recharged without issue. -- 3. To better understand the problem, could you please try charging the battery on its own (not installed in the vehicle) using the appropriate charger? Friendly Reminder: For standalone charging,it is advisable to use a compatible charger (DC, Rated Charging Voltage: 14.60 volts), to the positive (+) and negative (-) terminals of the battery. Usually a lead acid battery charger is not available to charge a lithium battery,may affect performance, safety, or battery lifespan. A suitable charger for the LFP20L-BS-STD battery is the 12V 5A charger. As our brand currently does not sell 5A chargers, we kindly ask you to purchase a suitable charger from another brand. Alternatively, using a 12V 2A charger is also feasible, though charging speed will be slower than with a 5A charger. -- 4.1)If the battery charges normally and works properly when reinstalled and starting your vehicle, the issue may be limited to a faulty digital display. In this case, the battery itself would still be functional, and we can offer you a partial refund for the inconvenience. 2)If, however, the battery does not charge at all or fails to hold a charge, this likely indicates an internal component failure. Should this be the case, we will promptly initiate the after-sales process to arrange a replacement for you. Please let us know the outcome after trying the above step. If possible, share any photos or videos showing the issue—this will help us assist you more efficiently. We apologize for any inconvenience this has caused and appreciate your patience as we work to resolve this for you. Best regards, Amy Aftersale service @TYKOOL Battery
