In the world of R/C we use different types of battery packs to power our toys. Li po and Ni MH batteries a very common and require a lot of attention to safety when we recharge them. So here are some tips that should help in the long run.
- First and most importantly we need to read the all safety precautions that come with our batteries. I generally ignore most instruction (measure one cut 20 times) but I at least look over the battery instructions that come with the batteries that I purchase. You will hear from time to time where someone was injured from an exploding battery pack. (Don’t be that person).
- I know you kind of cringe when you read that it will take 2, 4, 8 hours to recharge a battery pack but you should at least be in close proximity of the battery being charged just in case there happens to be an issue.
- Inspect you battery before charging. Don’t charge it if the I the cable or battery appears to be damaged. Especially if the battery looks like it is bloated.
- Use a flame proof charge bag. This will help contain the damage if the battery catches fire or explodes. I also will use a clay pot and dish to put the charging bag in for extra protection.
- Always monitor the temperature during the charging process. I will use a infrared temperature gun. If the pack being charged has an issue I will not get burned.
- Make sure that you charge area is dry. Avoid moisture.
- Always let you’re batteries are cool before recharging them.
- New recharge your batteries in extreme heat or cold.
- Make sure all your connections are tight to prevent and short circuits.
- Don’t be stingy. Buy extra batteries and have them charge at least the night before you head to your R/C spot. It kind of sucks that you spend 1 – 2 hours charging a battery for 10 – 20 minutes of fun.
- Invest in a battery checker to see how much power you have in your pack. This is especially important if you are flying aircraft. (Gravity is not your friend). I use the CellMeter-7 digital battery capacity checker for LiPo Li-Ion and NiMH NiCad batteries. A quick check before you start up will save you a lot of problems.
