Shipping Delays For Dangerous Goods

As per our shipping information, by ordering dangeours goods your order will have a "ROAD ONLY" sticker placed on the parcel and your order will be road express freighted instead of air. If you are out of state this can delay your order by around 1-2 days for major cities and longer for rural areas.

Battery Warranties

All batteries sold by Phaser FPV carry a 7-day warranty.

Once you receive, you should immediately check the cells and notify us of any faulty so we can rectify the issue.

An acceptable voltage range of a newly purchased pack is 3.60-3.90v per cell for lipos and all cells should be within 0.05v of each other. 

The reason warranty is so short is for several reasons. There are just too many variables in what could have happened to the batteries once they are used. Some include:

  • We can't be sure how fast it has been discharged
  • We can't be sure how low the battery was discharged
  • We can't be sure how fast the battery was recharged.
  • We can't be sure if they were paralleled incorrectly and another battery has caused the damage.
  • We can't be sure if one cell has had a slight hit that is not completely visible and that's the reason for the dropped cell/voltage being bad.

Safety Information For Batteries

  • Read all safety warnings and instructions that are included with your battery before use.
  • Batteries should NEVER be left unattended while charging and always charged in a fire-retardant container like a Lipo Sack or Bat-Safe. 
  • Keep a dry fire extinguisher nearby or a large bucket of dry sand, which is a cheap and effective extinguisher if something ever goes wrong.
  • Do not charge batteries near flammable items or liquids.
  • If your battery becomes "puffed" or damaged discard it asap as per next point.
  • Although environmentally friendly, lithium polymer cells must be FULLY discharged before disposal. Use a resistive load (light bulbs, for example) to accomplish this. If batteries are disposed while still partially charged they pose a potential fire hazard. Discharge damaged batteries at an acceptable rate and dispose of once all energy has been drained.
  • Be absolutely sure that the Lithium Polymer charger settings are correct for the battery pack being charged – both voltage and current settings. 
  • Never charge or store batteries inside an automobile especially on a hot day or any other place where the temperature may exceed 140F / 60C.
  • KEEP BATTERIES AWAY from children and pets at ALL times.
  • Never discharge below 3.5V per cell as it may cause permanent damage and void warranty
  • Batteries may explode if damaged or disposed of in fire
  • Do not put the loose cells in a pocket, bag, or drawer where they could short-circuit against other items, or the battery tabs could be pressed against each other.
  • Take care that the cells are not punctured, especially by metallic objects like hobby knives.
  • Always charge your batteries at 1C no matter what manufacturer specifications say. This will make sure you get the most life and performance out of your battery.
  • If the electrolyte in the cells should get on your skin, thoroughly wash with soap and water. If in the eyes, rinse thoroughly with cool water. Immediately seek medical attention for this, or for burns.

Charging & Other Battery Information

So you just got into FPV Racing, you have bought all these batteries and a charger, but don’t really know what you’re doing? Make sure you read the very inportant safety warnings above and here is some tips and tricks below.

GOLDEN RULE 1 

ALWAYS be nearby when charging, DO NOT leave the house or leave unattended. It is recommended that you also charge inside a LIPO bag or have a portable fire extinguisher.
If you do not listen to rule number 1. Your house may catch fire. This happened only last week to a guy in Australia. The battery was 6 months old. Inspect your  batteries before charging, looking for tears, deformations or swollen packs. Also check cell voltages to make sure that they are reasonably close and that all balance lead connections are undamaged and functioning correctly.

GOLDEN RULE 2  

Always BALANCE Charge. Do not use charge or fast charge. ONLY BALANCE CHARGE
GOLDEN RULE 3

If the battery becomes punctured/cut or “puffs” Discard it, do not charge!

Charging

Here is an example battery

1300mah 4s 65c – It also has the following specs from Manufacturer

Capacity(mAh) 1300
Config (s) 4
Discharge (c) 65
Weight (g) 176
Max Charge Rate (C) 10
Length-A(mm) 75
Height-B(mm) 35
Width-C(mm) 36

1300mah = How much power this battery stores – Generally the more power, the bigger and heavier the battery.
4s = How many cells. Each cell full charged is 4.2V . A 4s (four cells) is a battery with 4 cells in series, meaning that the voltage is additive. When fully charged a 4s battery will measure 16.80 volts as a sum total of the 4 cells, each being 4.2v when full.
65C = How much current battery is capable of delivering. In this example, it would be 65×1.3 = 84.5 Amps (constant discharge).
However most manufacturers are very creative with their numbers, its generally just best to use it as a guide on how good the cell is / how good resitiance/quality is.
Max Charge Rate (C) = The Max Charge Rate

On all batteries  we recommend you charge at 1C – This means you charge at 1300*0.001 = 1.3 Amps
If you are charging at 1C, it will take approximately 1 hour to complete the charge. 2C, it will take 30mins. Etc.

Some batteries (like above) have a max charge rate of 10C, so theoretically you could charge at 1300*0.001*10 = 13 Amps!

Now if I was out in the field and I really needed a battery fast, I may do this, as its within specifications, HOWEVER there is some evidence that charging faster can result in less life cycles over time. If you must charge faster consider charging parallel arrangements.

FAQ

What voltage should I not go below to protect my batteries?

Voltage should never go below 3.5v when at rest. Usually, I have my alarm go on at 3.5v, then land and battery come to 3.7 at rest. Note that this is per cell. You can monitor this on your OSD or you can simply multiply your cell number by 3.5 to find the total voltage for low voltage cutoff. On a 4 cell it would be 3.5v x 4 = 14.0v. 

When should I put my battery into storage?

If you aren’t using your batteries for 1-2 weeks or more, you should put lipos into storage to ensure they last.

Each cell should be 3.8-3.85v each for storage. Most chargers will discharge or charge to storage voltage automatically for you.
