NEW! KOKAM LI-PO SAFETY GUARD
Part Number: LIPOSG-4S
Kokam has developed the new Safety Guard to prevent overvoltage when charging LiPo packs with a current-regulated LiPo charger. When connected between charger and battery pack Safety Guard limits charge voltage to 4.2 volts per cell. Many LiPo chargers have selectable output voltages for charging LiPo packs in various configurations (2S,3S,4S, etc.). If you accidentally apply a too-high voltage to a pack, the pack will be damaged or destroyed. Safety Guard prevents overvoltage damage.
Safety Guard has other important features like making charging LiPo packs possible with sources not specifically designed for that purpose. (See the manual for Safety Guard under the SUPPORT section of the FMA website for more information).
Retail: $12.95
Voltage Limiter for Charging 4 Cell Lithium Battery Packs.
Size: 1.06
Ratings: 16.8V +/- 0.2V Max. output voltage
Outputs: Maximum input voltage - 30VDC; Maximum charge current - 20A; Maximum discharge current - 10A
Applications: Used in Combination with Charger for Charging LiPo Battery Packs.
LIPOSG ManualUsing Safety Guard with certain NiCd/NiMH fast chargers
CAUTION: Do not charge LiPo packs with a high cell count fast charger, such as
FMA’s FC700 Super Nova. When Safety Guard stops the charge, some current may
continue to flow. If the charger thinks the pack is still connected, its output voltage may
increase, possibly to as high as 50V. If Safety Guard is forced to dissipate high voltage/
high current indefinitely, it may fail, which may damage the pack and possibly cause a
fire. If your fast charger can charge packs of more than 7 NiCd/NiMH cells in series,
do not use it to charge LiPo packs through Safety Guard. Such chargers have
a DC/DC converter that boosts input voltage from a 12V power source to charge packs
with more than 7 cells.

Kan niet vaak genoeg gezegd worden.
Hierboven is geen uitzondering (en velen weten dat).
Dus: gezond verstand gebruiken bij LiPoly packs.
Groetjes,

een van onze forum sponsors heeft heel goede lipo laders voor een heel goede prijs.
