XVI. LiPO BATTERY SAFETY GUIDELINES (CONT)
CHARGING INSTRUCTIONS:
1. Venom Power™ LiPO cells feature a separate balancing plug that isolates each cell in a pack and charges it independently. This ensures that all cells
peak equally and discharge at the same rate during use preventing one or more cells from discharging past their safe low voltage cut off rating. The
balancing plug can be identified by the multi wire Molex plug.
2. Charge each battery pack individually. Never charge battery packs in series. Charging packs in series may result in improper charger cell recognition
and an improper charging rate that may lead to overcharging, cell damage and fire. We recommend using the Venom Power™ LiPO Balance Charger
(VEN-0652) when charging your LiPO batteries. The LiPO Balance Charger is designed to automatically peak charge individual pack cells (up to 5 cell
packs) with convenience and ease.
3. Always check to make sure that your charger settings match those listed on the battery pack label. Refer to the battery label for the proper cell count
and charging amperage setting. Selecting a cell count or amperage charge rate other than the one listed on the battery pack will damage the battery
and may cause a fire.
4. Make sure the battery connections are connected in the correct polarity. A wrong connection will damage the battery and may cause a fire.
5. Always check battery pack voltage before charging. Do not discharge LiPO batteries below 3.0 Volts per cell. The voltage of a typical LiPO cell at
rest is 3.7 Volts. If the battery pack appears swollen or damaged, DO NOT attempt to charge it. Check the voltage and follow Step 5 from the Safety
Guidelines section.
6. Do not charge at over 1C current. C= battery pack mah capacity ÷ 1000. Divide the battery mah capacity by 1000 to determine the proper charge
rate. Example: 1200mah ÷ 1000 = 1.20 Amps Charge Rate for Venom Power LiPO Battery Packs, example:
a. 800mah Capacity = 0.80 Amps
b. 1200mah Capacity = 1.20 Amps
c. 2000mah Capacity = 2.00 Amps
7. Do not peak charge to more than 4.2 Volts per cell. Example: A 2S Battery Pack contains two cells, therefore the peak voltage should not exceed 8.4
Volts.
8. Battery Temperature is critical. For optimum performance in cold climates, warm the pack to 100Fº/ 37Cº before use. Please use the following
guidelines:
a. Charge Temp Range: 32 - 110Fº / 0-43Cº
b. Discharge Temp Range: 32 - 140Fº / 0-60Cº
c. Storage Temp Range: 40 - 80Fº / 4-26Cº
9. If the battery exceeds the temperature guidelines as above, isolate the battery pack and follow Step 5 from the Safety Guidelines section.
NEW BATTERY BREAK-IN:
1. New LiPO battery packs may require 12 or more charge/discharge cycles before the battery’s optimum performance is reached.
2. During this time, it is recommended that the battery pack is not discharged over 7C. 7C = 7 x 1C, where 1C= battery pack mah capacity ÷ 1000.
Example: [(1250mah ÷ 1000) x 7] = 8.75 Amps
Recommended Maximum Discharge Rates During Break-In Period
a. 800mah Capacity = 5.4 Amps
b. 1200mah Capacity = 8.4 Amps
c. 2000mah Capacity = 14 Amps
DISCHARGING INSTRUCTIONS:
1. Never discharge a LiPO battery pack at more than the manufacturers recommended discharge rate. The discharge rate is:
Battery pack capacity (mah) ÷ 1000 x Pack C rating
Example for 15c packs: (3200 mah ÷ 1000) x 15c = 48 Amps
Example for 20c packs: (2100 mah ÷ 1000) x 20c = 42 Amps
