Hyperion does not recommend or allow G3 Lipo Terminal Voltage to be set higher than 4.200V. Therefore any + setting above
0mV VOIDS your WARRANTY for your LIPO battery pack. Whenever ALL cells in a pack exhibit puffing, over-voltage charging (or
severe over-discharge) is indicated and warranty will not be honored.
WARNING! By setting the TVC to any POSITIVE SETTING above 0mV, you ACCEPT ALL RESPONSIBILITY for Damage to your
battery, Fire, Injury, and any other Loss which may result. If you do not agree to accept all risk, DO NOT OPERATE YOUR
CHARGER UNLESS ALL MEMORY POSITIONS ARE SET TO DEFAULT 0mV TVC position! Furthermore, it is your
responsibility to insure that no other person uses your charger if TVC is set to greater than +0mV, and to reset ALL memory
positions to TVC 0mV default before selling your charger or giving it to others.
Positive settings (+5mV or higher) may be desired by racers looking for competitive advantage, and therefore +TVC has been
demanded as a feature by racers. However, it is the official position of Hyperion that Competition Sanctioning Bodies are
irresponsible in allowing over-voltage charging via their rulebooks, and therefore that both users and their sanctioning bodies are
FULLY responsible for any Loss, Damage, or Injury that may occur due to over-voltage charging of batteries. Let’s say it again:
If you want to use Positive TVC settings, you may make that choice. But ONLY if you personally deem it desirable, AND you are
taking FULL RESPONSIBILITY for any and all results which may arise. We encourage you to petition your sanctioning body
to stop allowing LIPO terminal voltages in excess of 4.200V, which are both potentially unsafe and without significant benefit, we
believe.
NOTE: PB (lead-acid) CHARGE also allows a TVC-like setting (CHARGE VOLTS). In general, PB should be charged at 14.4V
setting. However, the Type of battery (wet vs gel vs agm, etc) and ambient temperature may dictate a lower or higher charger
voltage. Consult your PB battery maker for advice, and use the CHARGE VOLTS setting at your own risk. If you have no
information on TYPE of PB battery you are charging, use 14.0V CHARGE VOLTS setting.
Lithium Care
To maximize your investment in Lithium Battery packs, do the following:
* ALWAYS Store your packs at 60%~70% capacity. After a day of flying, use STORE Mode to achieve this. It is especially
harmful to store lithium packs fully charged, and should be avoided for more than a few hours at most.
* NEVER discharge cells beyond 90% of capacity (plan for 80% max). NEVER fully discharge lithium packs.
* STORE your packs in a cool, relatively dry location.

for full details on best care practices for your valuable Lipo batteries.
LIPO MAX C – Under USER SETUP menu you will find a setting to allow setting of Maximum “C” charge rate for Lithium
Polymer (3.7v/cell type) batteries, with options of 1C to 5C (2C is Default). Note that MAX C attainable will depend on the
Amps Max and Watt Max rating of your charger, and pack capacity/voltage.
NOTE: It is entirely YOUR responsibility to determine the SAFE Max C for your LiPo pack.
HYPERION original LCL, LCX, LVX, LVZ types, 2C max charge rate.
HYPERION GENERATION 3 25C/35C/45C packs, 6C max charge rate
HYPERION GENERATION3 5C Rx packs, 4C max charge rate (20C LiFe Rx packs = 5C max charge)
HYPERION SWIFT G3 CAR PACKS - 6C max charge rate
(ALL Hyperion G3 LIPO packs ever produced support 6C rate, regardless of 2C or 5C charge cautions appearing on early packaging)
If using other than Hyperion lithium packs, consult your battery’s documentation for allowed C rates, before exceeding 1C charge
rate. If you don’t know the allowed max CHARGE rate for your pack, never exceed 1C rates.
Net/Duo FAQ
* The discharge function is supposed to be 10A Max
(5A for NET3-AD), but when I discharged my pack I got less current. Why?
Both charge and discharge functions are limited by both watts and amperage; whichever comes first.
Charge: 180W and 15A maxes per port (DUO3)
Discharge: 50W and 10A maxes per port (DUO 3)
- If you are discharging a pack which starts at 10V, for example, the initial max current(A) would be: 50W/10V=5A
(note that as the battery voltage drops during discharge, current will rise)
- If charging a pack which starts at 10V, then max current would be: 180W/10V=18A. BUT current is limited to 15A,
so the max you get will be 15A, since the current limit is reached before wattage limit…
NOTE ALSO: Lithium batteries use CC/CV charge curves, so current will always fall as the battery becomes more charged.
* Why does the charger not give the END buzzer (or FLAT CHECK error), even though the pack has been attached for a
long time? (I have checked and buzzer is set ON)
- LIPO/LIFE: Most likely, you have set a charge rate lower than 1C, and the charger cannot terminate CC/CV as required
current at that point is too low. Assuming your battery is of decent quality and condition (if not, do NOT charge it!) there is NO
reason to charge at rates below 1C. Charge again at 1C and observe results. Note also that END buzzer will NOT sound until the
charger achieves target cell balance. For badly out-of-balance packs or large capacity packs, this could take up to an hour.
- NiCd/NiMH: Same answer as Lipo/LifePO4 above (for a different reason). Try charging at a higher rate. We have found that
many NiMH packs on the market today are poorly made, and do not signal delta-v (indicating end charge) properly when
charged at low rates, and sometimes even at higher rates. Try setting delta-v in your charger menu to a lower value. Try
charging at a higher rate (check battery for over-temp!). If nothing works, get a pack of cells from a known quality brand (Sanyo,
GP, etc) and test your charger.
* Why do I see “0” current flowing during charge at regular intervals? Is it a “Pulse” charger?
No, the charger simply pauses charging at intervals in order to make extremely accurate readings of cell/pack condition.
