The LIPO-402 and LIPO-102/202 chargers, available from Kokam/USA, are ideal for charging
LiPo battery packs.
The Versatile Adapter, part number 501MC, is a great companion
for any charger. It provides Futaba, JR, Airtronics, Deans and
Molex connectors, plus 2.1mm and 2.5mm power jacks, enabling
you to easily connect your cells and packs to the charger. The
chargers plug right into the 2.5mm power jacks.
To determine the LiPo pack configuration that will work best in
your application, use the LiPo Calc design tool on the Kokam/USA
Web site, www.kokamusa.com (or www.fmadirect.com).

Sport VRLI
voltage regulator / LED indicator for powering
radio control receivers and standard servos
Model VRLI1-LIPO: for 7.4V Lithium Polymer battery packs
Model VRLI1-NCD: for 4.8 and 6.0V NiCd and NiMH battery packs
Features
Designed specifically for powering flight electronics (receiver and servos) in engine-powered
radio controlled aircraft.
VRLI1-LIPO regulates 7.4VDC (from two Lithium Polymer cells in series) to 5.0VDC.
VRLI-NCD regulates 6.0VDC (from five NiCd/NiMH cells in series) to 5.0VDC. Low drop-
out regulator maintains maximum 0.5V drop, even if battery voltage decreases under full load
(e.g., if battery outputs 4.8V, the VRLI outputs 4.3V minimum).
Supplies 2A continuous current, sufficient for driving up to five standard (moderate torque)
sport servos, as well as micro and mini servos. This unit is not recommended for use with
digital servos.
LEDs show two battery voltage check points—helpful for stopping radio use before battery
packs fall below 2.5V/cell (LiPo); 1.13V/cell (4-cell NiCd/NiMH); 0.90V/cell (5-cell NiCd/
NiMH).
Easy to install: connects between radio switch and receiver using universal plug and jack.
Note: When using LiPo batteries in electric-powered models, use an FMA LiPo
Electronic Speed Control instead of the Sport VRLI. FMA LiPo ESCs work with LiPo,
NiCd and NiMH batteries, and have a Battery Eliminator Circuit (BEC) to power the
radio system.
Kokam/USA Lithium Polymer cells are the next-generation replacement for NiCd, NiMH and
Lithium Ion cells. This unique power technology offers high energy density, low weight, long
life, safe operation and environmentally-friendly chemistry. Order Kokam/USA cells and packs
through the Kokam/USA Web site, www.kokamusa.com (or www.fmadirect.com). LiPo technical
and application information is available in the Support section of the Web site.
