Thank You for Purchasing Relion Lithium Battery. We Truly Appreciate Your Business. This

Thank you for purchasing Relion Lithium Battery. We truly appreciate your business. This document is designed to aid your experience by providing information about charging, basic troubleshooting, etc. Please let us know if you have any questions. CHARGING ______Because of the different parameters required for charging lithium ion batteries as opposed to lead acid batteries, we do not recommend using a standard lead acid charger for your RELiON Battery. Using a lead acid battery charger with lithium ion technology presents risks of damage, decreased lifespan, and overall suboptimal performance. We pride ourselves on providing the very best batteries on the market, and we want all of our customers to have the tools to get the very best performance possible. Relion Lithium chargers are specifically programmed for lithium ion technology. These chargers are manufactured by Pro Charging Systems and Progressive Dynamics, they give you both the trusted brand and confidence that your batteries will charge properly every cycle. If you already have a charger with an AGM setting this is usually appropriate or featuring adjustable settings, you will need to alter those settings to accommodate the lithium ion batteries. Each Relion Battery has a rate specifying the maximum amount of current with which it can be charged. It is important to make sure that you do not charge the battery with higher current than rated. Because of the 99% efficiency of the technology, bulk charging is normally the only stage necessary to charge our lithium ion battery. If your charger can be programmed to deliver constant current and charge up to 14.6V, there is no need for an absorb phase. Some chargers require both a bulk stage and an absorb stage, programmed at different voltages. In this case, you would set the bulk at 14.2V and absorb at 14.6V. RELiON lithium ion batteries need to reach between 14.4V and 14.6V to be at full charge and deliver optimal results. If your charging voltage is higher than this range and cannot be programmed to a lower voltage, it is not recommended for use with our batteries. Likewise, if your charging voltage is lower than the required 14.4V–14.6V range, your Relion Batteries will not reach full charge and thus will not perform to their full potential. If a float charge setting is necessary to program your charger, it should be set to 13.8V. However, one of the many benefits of Relion Batteries is that they lose less than 9% of their energy per year in self discharge. This allows you to come back to a nearly fully charged battery even if it has been left idle for a long period of time. Please note that for most orders, we fully charge our batteries prior to shipment for our customers’ convenience. In some cases, either due to customer request or expedited shipment, batteries are shipped at 40% charge. This is the best voltage for storage of lithium ion batteries. The 40% state of charge allows the batteries to be stored with minimal aging and self discharge. If you have any questions about charging, please do not hesitate to contact a RELiON Power Pro . We are more than happy to assist you in finding the proper charging solution to suit your needs.

TROUBLESHOOTING and USER GUIDE ______

RELiON Batteries are outfitted with a sophisticated Battery Management System (BMS) that protects against most outside factors that would normally damage a battery. The BMS provides these features:

 Low Voltage Protection – Automatically disconnects at 8V  Over Voltage Protection – Automatically disconnects at 15.8V  Short Circuit Protection – Automatically disconnects  Reverse Polarity Protection – Automatically disconnects  Internal cell balancing – Automatically balances cells  Charge Balancing – Independent balancing for batteries connected in parallel and/or series  Series and Parallel connections - contact RELiON POWER PRO’S for these applications.

If your RELiON Battery is not functioning correctly, please follow these simple steps or contact a RELiON Power Pro. First you need to determine battery voltage. Battery voltage can be read by using a standard DC volt meter. (Follow manufactures instructions and safety measures). A fully charged 12 volt battery should read 13.5 volts, an empty battery will read 12.2 volts. If your BMS engages, your battery internally disconnects and will read zero volts. Because of this, a charger will not detect a connection and will not charge the battery. This can be misinterpreted as a problem with the battery but is actually RELiON battery protection. The first troubleshooting step to take if your BMS engages is to simply disconnect each terminal and reconnect. In many cases, this will disengage the BMS and your battery will be back to normal working condition. For some issues, such as BMS protection against low voltage, your Relion Battery can be reenergized by applying (jumping) 12 volts to the terminals, much like jump starting a car battery, this can be easily done with jumper cables. If this does not work, it will need to be charged in parallel with another battery that has enough voltage at least 10 volts in a 12 volt battery, this allows the charger to detect a complete circuit. You can use any type of 12 volt battery. Connect your charger directly to a working 12 volt battery. Then, connect your Relion Battery in parallel (positive to positive, negative to negative) to the first battery. The Relion Battery’s BMS will reenergize, bringing the battery back up to its voltage prior to the BMS kicking in. After about 20 minutes, reconnect the charger directly to the Relion Battery, and the charging process will continue normally. In instances of Series or Parallel Connections, your RELiON batteries must be maintained to voltages within 50 millivolts (or .05 volts) of each other. If your system gets out of balance you must charge each battery independently with a 12 volt charger. Once charging is complete, let batteries stand for 4 hours and then check voltage if the batteries voltages are not within 50 millivolts of each other… discharge higher voltage batteries down to the lowest voltage battery, this can be done with a small 12 volt light or similar discharge source. A 2 amp discharge (a single light) at 30 second intervals should reduce voltage in small increments… repeat the process as needed until all batteries voltages are within the 50 millivolt range. Keep in mind that the batteries you purchase must be suited for your application. If the batteries are being asked to deliver beyond their capability, issues will persist. Our RELiON Power Pros are here to ensure each and every customer receives the battery (or batteries) ideal for their application.
