EOS 1210i comes with male 4mm Bullet connectors also known as banana connectors attached to the power INPUT cables These cables are appropriate for attaching directly to most high quality AC DC 12V power supply units such as the BK Precision USA model 1692 Also included are large Terminal Clips with matching 4mm female bullet connectors for attaching directly to 12V lead acid batteries Output side connector cable assembly is also supplied Carefully solder your preferred battery connector to the free ends If you make up additional output cables note that MINIMUM inner cable diameter should be 2 5mm 14ga and MAXIMUM cable length is 20cm 8 It is critically important that you use either a fully charged 12V lead acid automobile battery or a high quality AC DC power supply in the range of 12V to 15V DC output with minimum current rating of 8A When charging high voltage batteries at high current an output rating of up to 25A may be required If you have any trouble charging after confirming that input and output cables are properly connected and of the proper materials be sure to check the charger on an automotive battery Many problems are associated with poor quality or inadequate switching AC DC power supplies If after carefully reading the following pages on usage you have any difficulty using the charger please refer to the final pages for troubleshooting guide and warranty terms Memory Position and
9. Hyperion EOS 1210 Charger User s Manual for 12101 A with A123 Mode Warnings The EOS 1210i is a carefully designed charger with many built in safety features such as reverse polarity protection input voltage error warning and cell count mismatch warnings for lithium chemistry batteries HOWEVER IT IS THE RESPOSIBILITY OF THE USER TO INSURE THAT THE CHARGER IS CONFIGURED AND USED IN A SAFE MANNER IN PROPER ENVIRONMENT Note that as cell count of lithium batteries becomes higher all warning systems become less accurate As such we strongly recommend the use of Hyperion LBA10 balancers when charging lithium batteries and especially so at AS or higher LBA provide much additional safety because the LBA monitors each individual cell for A123 cells ALWAYS use balancer e Always be sure that the charger is properly configured for the correct battery type e Be sure that the batteries you charge are capable of charge at the rate you select e Never charge batteries unattended Charge only in a fire resistant environment such as on concrete or brick rather than wood surfaces Do not charge near easily flammable materials Do not charge batteries inside a model Charging outdoors is recommended whenever practical Use only high quality gold 4mm bullet connectors for charge output cable connection to the charger See setup e Insulate all Output connectors to eliminate the possibility of short circuit Damage cau

11. ark the estimation is very accurate but at 50 mark is likely less accurate Note also Case 1 When TCS is set for 50 to 60 for battery storage When the selected charge percentage is reached the charger stops and sounds the finished tones Case 2 When TCS is set for 61 or higher for quick charge The EOS 1210i will NOT automatically terminate the charge when your pre set percentage is reached Instead it sounds a unique double tone repeatedly for an interval of 10 seconds It is up to the user to manually terminate the charge at that point or to do nothing and allow the charge to continue until 100 is reached This is a safety feature to insure that packs are not inadvertently undercharged And since the point of speed charging is that you want to fly NOW it is unlikely that you would miss the double tones when they do sound as you are waiting nearby to fly Charging in Excess of 1C Rate Every Hyperion lithium polymer battery ever produced is capable of reliable charging in excess of 2C Yet until recently Hyperion has only ever specified 1C charge rates Why Because extensive test and our experience have shown the following e Charge voltage in excess of 4 2V cell is damaging to high rate 15C lithium cells in particular e The potential for damage from over volt charging increases with charge rate e Tests of other brand chargers prove that many are poorly regulated and that even some of the more expensive units re
