Great question jungyul. For storage, a cell voltage of 3.7V - 3.8V is good; or 7.4V-7.6V. The end voltage is adjustable in most chargers, so not everyone uses the same voltage, but 3.8V is our recommendation and a safe place. LiPo chargers have a "Storage Charge" mode, and that mode will either discharge or charge the battery until the battery is 3.8V a cell. Please use this mode to store your batteries. Let me know if we can help answer any more questions. Thanks. -Brett

I had a few batteries stored fully charged. Went to fly but it sure drains a lot faster now. Guess the lipos may need to be replaced 😥

Personally, I’ve found using the impedance setting on my charger to be the next step on a battery inspection, after a good visual check. Checking for cell resistance will tell you if you have a cell that is beginning to fail.

Hey coco. Charging below 1C is perfectly fine and safe to do. Very low charge rates are best for longtime battery life, but offer reduced performance, or in R/C terms, lower "punch" and it takes longer to charge a battery.

What does Cycle charge mean? Also you mention 5000mAh = 5apm = 1C, so if my batteries are 6800mAh = 7apm = 1.125 C? (My batteries are: 11.1V 6800mAh 3S 120C Smart G2 Basher Lipo)

@AMain_Hobbies

8 ай бұрын

You're 6800mAh batteries would have a 1C charge rate of 6.8amps. To find 1C, divide the battery capacity by 1000. So a 7200mAh battery would have a 1C of 7.2amps; a 2200mAh pack would be 2.2amps. For a cycle charge, it's the philosophy of "breaking in the battery" before pushing it to the limits. Some chargers have a cycle charge mode, where the unit will first charge the battery up and then discharge the battery back down, effectively putting a "cycle" on the battery. Some people do this a few times with a brand new battery, some people do not, but that's the idea of cycle charging a LiPo battery. -Brett

In the video he said throw away any batteries the have puffed or bulged. Most of my batteries have slightly puffed but still balance and charge and hold a charge. So throwing them away is a waste of money because they still work. Now I did have a battery that puffed and I felt it was getting worse, so I threw that out. But generally all lipos puff slightly.

Christ!...having to keep a battery in a safe in a safe because it is unstable?. I recently built a cross rc mammoth which came with a LIPO. I had only used NIMH in the past but having researched the care and issues surrounding the use of LIPO has really put me off using it. For the added performance they give, I feel unless you are an RC Devotee, they are not worth the extra worry. I personally just use crawlers on a very casual basis, and they often stay stored for ages.

I disagree. A lipo with very different balance has most times a bad cell. Balancing it will work, but your battery often again draws more from one cell. Check your batterys "Internal Resistance" if your charges has that function. If the cells have very different IR dispose of it in a proper way.

Only problem with how protek states to drain is it could get a "recharge" when not being actively drained. this is why it's BEST to drain SHORT CIRCUIT (cut off connectors and twist stripped wire ends together) THEN dispose of in trash. the "salt water" doesn't actually do anything except corrode the wires off making the battery even MORE dangerous.
