Charger Tips

CHARGER TIPS:

1. Your always there to monitor the cells (don't leave it unattended) 
2. Get a quailty battery (Thunder Powers are great) 
3. Quailty LIPO CHARGER, you MUST (notice the caps) get a LIPO CHARGER. You cannot charge lipos with ordinary chargers for NI-CD, etc.
4. Investing in a good balancer is a wise decision 
5. Get well known Lipo batteries. DO NOT get no named cheap batteries just because their cheap because you might have to spend another $10,000 fixing your house if it burns.
6. It is not mandatory for you to get a fire-proof box but it is recommended
7. Do not charge/store your lipo on your plane/heli
8. Do not charge near flammables/explosive substances (common sense)
9. If your pack is damaged/broken, soak it in salt water for a while then contact your hazardous waste disposal company for advice on throwing it out
10. DO NOT OVERDISCHARGE YOUR LI-PO BATTERY (don't fly until you can't get the rotor to turn anymore)!!!
11. Store in a dry, cool area with some sort of case (so it won't get damaged)
12. Connect your charger to the main power supply first then your battery to your charger to prevent shorting your pack
13. Double, Triple check your setting on your charger before you charge your battery
14. Read the charger manual before you charge
15. Always solder the female plug onto the battery.
16. If any single cell in your lipo drops below 3.0 volts your pack may be ruined. 9.0 volts for a 3 cell pack is too low of a setting on a monitor.
17. IF you crash, set your lipo aside in a safe place for a while, even if it looks undamaged. Internal shorting can occure and cause a fire
18. When setting up a lipo power system, always try to match battery Mah capacity to be at least, over the expected current draw from your motor and ESC systems. Always use good quality power connectors like deans or similar. Poor quality connectors can = meltdown = burnt model = burnt house or car = dead modeller.
19. Li-pos should NOT get warm during a charge. During a discharge, they should not exceed 140F (worst case, lower is obviously better). 

 Be Bright, Charge Right
 Charge Wrong, Your Gone

Charger

Device used to recharge batteries, usually supplied with the radio if NiCd batteries are included.

LiPo charger: It is imperative that you use a specially made LiPo charger to recharge your batteries. Never use a charger designed for other types of rechargeable battery, the charging current will be wrong and there is no safety switch-off, the need to stop all LiPo chargers overcharging. Overcharging a LiPo battery, the battery caught fire, there are reports of exploding batteries.

Charge Rate: Always make sure that your charger at the same voltage as your LiPo battery. LiPo batteries are commonly used in batteries, so many chargers have a variable fee setting so that you can charge more packs. Check the label on the battery or battery to determine the output voltage. Place the charger on the same voltage, a little lower no problem, but a higher voltage damages the battery and can be dangerous, as in Section 1.

Excessive Discharge: LiPo batteries can be recharged at any point during the discharge with no ill effects or damage. However, if you fully discharge the battery and try to successfully - and that's unlikely, since LiPo manufacturers have built in a safety device to prevent this - it will not recharge. This is because, deep discharge destroys the chemical basis of the battery and make it unusable.

LiPo Charging: BagLegen Always store your batteries in a bag while they are chargeable. The bag is a fire and explosion protection so that if a problem occurs while the batteries are charged, you will be safe. They are fairly inexpensive and widely available from electrical and hobby stores. Never leave LiPo batteries, the charge will be unsupervised. Always turn the charger when the batteries are charged and allow them in the bag before they cool.
