HYPERION Lithium Balance Adapter - For Lithium Polymer and A123
2007-01-25
Warnings:
•
Batteries can be a fire hazard if
charged or discharged improperly.
Always use your battery charger and
batteries as directed by the makers.
•
Never Charge Batteries unattended
•
Charge in an area free of flammable
materials, on non-flammable brick,
concrete, etc
•
Keep Batteries, Charger, and
Balancer AWAY FROM CHILDREN
and PETS!
•
Never attempt to charge an impact-
damaged (crashed) battery pack
•
Packs which are chronically far out
of balance may be damaged and
should be discarded
Photo Notes: 1: Option Cable #HP-EOSLBA10-DPC required and charger must have DataPort option
2: Option Set #HP-EOSLBA10-MSC required for Networking LBA10
The Hyperion Lithium Balance Adapter (LBA10-A) is an extremely versatile device. It can balance either lithium 3.7V or A123 3.3V packs - with
“balance connector” correctly attached to the pack - in voltage range of 2S~6S three ways:
•
Stand-Alone* discharge method (without using a charger or discharge device)
•
Loaded discharge method (using any load device for discharge load)
•
Balance while Charging (using a LiPo or A123 compatible charger)
*Standalone is called “Disconnection” mode, because the path to charger/discharger is disconnected
To use the LBA10, a Balance-Connector must be wired to your battery pack. The LBA 10 comes with 2S and 3S harnesses which fit Hyperion,
Polyquest, Poly-Q, E-Tec and some other brand lithium packs. 4S to 6S harnesses are available separately. (Hyperion A123 packs use 7-pin “6S”
connector for all packs, 2S~6S). Hyperion also offers JST EH and JST XH type harnesses, which fit many other liPoly pack brands. If your pack
does not have such a connector, and you are confident in your ability to install one, you may purchase the connector Part #HP-EOSLBA-MC-P4
(2S~4S packs), #HP-EOSLBA-MC-P5 (5S packs), or #HP-EOSLBA-MC-P6 (6S LiPo, all Hyperion A123 packs), and attach it according to the
diagrams at the end of this manual.
Note: Packs with Hyperion-style “6S” balance connectors wired correctly can connect directly to LBA 10 without intermediate harness.
USE OF THE LBA10
Note: LBA10 usage is identical for both Lithium Polymer and A123 lithium cell types. By default, the LBA10 is in “LiPo” mode when the battery is
connected. To enter “A123” mode, push the MODE/RESET button for 2 seconds, until you see the Red A123 Mode LED light up. See technical
differences and cautions later in this document.
Prepare your LBA by soldering a mating Main Connector for your battery pack to the red/black PACK CHG (LBA OUTPUT) wires
Let’s attach your lithium pack to the LBA in Disconnection Mode to see how the LED indicators work…
•
Be sure the NETWORK switch is set to MASTER
•
Select the appropriate harness for 2S~6S. Connect harness to LBA at port marked ‘Balance Harness’
•
Connect your Lithium pack to the LBA Multi-Connector
•
The LiPo 3.7V MODE LED will blink at one-second intervals
(if A123 pack, hold down Mode/reset button 2 seconds now to switch to A123 3.3V mode)
•
WITHIN 12 SECONDS, Connect your Lithium Battery Connector to the connector you installed on the LBA OUTPUT wires
•
watch the MODE LED
•
MODE LED will be ON continuously in Disconnection Mode … OR will show an ERROR:
o
Flashes Twice:
Battery Voltage higher than expected
o
Flashes Three Times: Battery Voltage lower than expected
o
Flashes Four Times:
Other Connection or Wiring Error
If you have errors, check to see that you have the proper harness installed and battery in good condition
If your pack is already very closely balanced, the LBA 10 will automatically shut down and turn off all LED. There is no work for the
LBA to do! After shutdown the LBA puts an extremely small drain on the battery. However, you should always disconnect the battery from LBA as
soon as possible after balancing is complete, especially for the smallest packs.
If your pack needs balancing, the LBA will go to work, discharging the cells with highest voltage. Each CELL LED will have one of these
three states:
ON SOLID:
Discharging that cell at max rate
QUICKLY FLASHING: Discharging that cell at low/medium rate
OFF:
That cell’s voltage is low, so no discharging
*LED COLOR: Cells 1-3-5 are always RED; 2-4-6 always GREEN. The colors just help you identify which cell is which.
If you leave the Lithium pack attached to the LBA now, it will continue discharging the high-voltage cells until the pack is very closely balanced.
When balancing is complete, the CELL Condition LEDs will each Flash, then all LEDs will go dark and the LBA will power OFF. At this point the draw
on the Lithium pack is very small (490uA), so you could leave the pack connected for extended periods without damage. HOWEVER, lithium packs
should always be disconnected from the LBA as soon as possible after completion. Charging should NEVER be left unattended!!
NOTE: When a lithium pack is first connected to the LBA, you start in “Disconnection” mode. When the LBA is not connected to a charger, the two
4mm gold connectors on the LBA are not insulated. In disconnection mode, these may freely touch each other without harm. However, if they
touch while in “Connection” mode, the LBA fuse will blow. To avoid this, use the connector covers included with your LBA10 to insulate the
connectors, whenever not connected to a charger!

NOTE: The LBA contains Auto-Cut circuitry to avoid over-discharging a badly out-of-balance pack, or a pack which starts with voltage too low
already. If any one cell ever falls below the protection limit, the LBA microprocessor powers OFF, regardless of balance state, and discharging is
stopped.
