The warranty is in effect from the date of purchase by the user (the “Purchaser”).

Please read the product manual carefully before installing and using the product. If the consumer fails to install, use and maintain the product correctly in accordance with the requirements of the instruction manual, which causes serious quality problems in the product, it is not covered by the warranty.

Warranty Procedures

After receiving the warranty request, we will provide customers with professional technical guidance within 24 hours on working days, assist customers in analyzing the problem, and help solve the problem and restore battery use.
If our product does not work properly, consumers need to assist us in completing all battery tests. When we both confirm that the product has quality problems, we’ll send a new battery replacement to the defective battery after it has been returned to our US warehouse by the pre-paid label we prepared.

Within 90 days from the date of purchase, if our products have quality problems and cannot work normally, we can provide refund or replacement services.

More than 90 days from the date of purchase, and within 10 years, if our products have quality problems and cannot work normally, we can provide replacement services.

Failures caused by (1) incorrect storage; (2) improper use (3) failure to follow the product instructions or to perform any preventive maintenance; (4) modifications; (5) unauthorized repair; (6) normal abrasion; (7) damage caused by negligence, including using the battery for a long time with high power but not timely charging; (8) not following the scope of application of the product; or (9) external causes such as accidents, abuse, actions or events beyond our reasonable control, or any other issue not caused by defects in materials and workmanship is not covered under the warranty.

Precautious

Please use the LiFePO4 battery charger specifically for that purpose.
Do not strike battery with any sharp edge parts, such as Ni-tabs, pins and needles.
Do not immerse the battery in water and seawater.
Do not use or leave the battery near a heat source such as fire or heater.
Do not reverse the position and negative terminals.
Do not connect the battery to an electrical outlet.
Do not throw the battery in fire or heat it and bend it.
Please tighten the battery terminals firmly and use appropriate size wiring, or it can result in overheating and battery damage
Do not connect the positive and negative terminals with metal object.
Do not transport or store the battery together with metal objects such as necklaces, hairpins etc.
Do not directly solder the battery and pierce the battery with a nail or other sharp object.
Do not directly connect the battery to a starter machine, our battery are not designed for starting engines.

Battery Storage Notice

The battery should be stored within the temperature range specified in the product specification. If the storage time exceeds 3 months, it is recommended that you charge the lithium iron phosphate battery. Otherwise, the service life of the battery may be affected. In order to protect the battery, please do not exceed the specified maximum discharge current, and do not be lower than the specified discharge voltage.

When you receive the product, please read the product manual carefully, which contains the installation method, precautions and detailed warranty terms of the product. When you use the battery for the first time, please fully charge it.

Precautions for Connecting Batteries in Series

To ensure optimal performance and extend the lifespan of your Enjoybot Battery packs, we require following the steps below to BALANCE THE VOLTAGE of your battery packs before connecting them:

Begin by charging each battery individually using a compatible charger. This will ensure that each battery is fully charged before proceeding to the next steps.
Once all battery packs are fully charged, connect them in parallel for a period of more than 12 hours. This allows for equalization of voltage between the battery packs.
After the parallel connection has been maintained for the required time, untie the parallel connection.
Use a multimeter to measure the voltage of each battery pack individually. Make a note of the voltage value for each pack.
Check the voltage difference between each battery pack. If the difference is ≤40mV, this indicates that the battery pack has reached a voltage balance.
Once the voltage balance is achieved across all the battery packs, you can safely connect them together to achieve the desired capacity or voltage for your specific application.
Once connected, charge the entire battery pack with a charger of the appropriate volts. (For example, if you connect four 12V batteries in series to form a 48V battery pack, then please use a 58.4V charger to charge the entire battery pack in order to maintain the voltage difference between each battery.)

Please note: Enjoybot battery is deep cycle battery, not designed for starting engines, it can not be used as a cranking battery due to BMS setting. When the boat's engine has started, the boat's engine needs continuous and reliable power for trolling motors, which is where enjoybot deep-cycle marine batteries come in.

An over-current protection device (circuit breaker or fuse) must be used. The surging current at the moment of start-up for trolling motors can be 5 times or more greater than the usual running current. Excessive current can cause over-current discharge and destroy the BMS beyond repair, which is not covered under Enjoybot LiFePO4 battery 10 year warranty.

Golf Cart/ Other Vehicles Usage Notice

Battery	Motor (Maximum Power)	Motor Controller (Maximum Current)
36V 100AH Pack	Less than 3000 watt	Less than 350 amps
48V 100AH Pack	Less than 3000 watt	Less than 350 amps
Single 36V 100AH	Less than 4000 watt	Less than 500 amps
Single 48V 100AH	Less than 4000 watt	Less than 500 amps

Excessive current can lead to over-current discharge, damage will occur to the BMS beyond repair and this is not covered under Enjoybot LiFePO4 battery 10 year warranty.

State Of Charge

When determining if a lithium-iron phosphate battery has any charge remaining, first turn off the power source to the device and disconnect all wires from the battery. Next, using a voltmeter or multimeter, test the voltage of the battery.

To help you better understand Enjoybot's capacity, please refer to the table below, parameters are for reference only.
