Ok, so I bought this and just received it, it says I can only store only lipo batteries up to 4000mah. I have two 7600 packs, can I store these?

You can store any kind of packs, as long as the packs don't touch each other and are stored in a cool place you'll be good, I store my lipo packs in the boxes they came in.

Sorry, that would be better answered by CTeck Support, there are temp and ventilation concerns for the areas where you charge the batteries. So honestly I am not sure.

While technically any battery could leak I have never had this happen to these high quality "eneloop" batteries. Keep in mind it is not so much the battery being left in the device as it is where the device itself is left dormant. If there are frequent temperature and humidity changes the device terminals are likely to corrode which could then damage the battery. As with even mechanical devices (such as springs) it is cycling count that eventually takes its toll. There is a lot of technical data available on long term storage and recharging. From what I know you want to allow them to store partially drained, but NOT "dead" as you can get polarity reversals. Also, it is worth the investment on a "smart charger" that will not overheat the battery and will automatically put the battery through beneficial "cycles" to improve performance and life. Also, it is worth monitoring voltages on all your good batteries... remember the pack is degraded by the weakest battery. In summary, store cool partially drained, smart-charge and never let them overheat.

The idea is do not over charge or discharge any Lipo battery (as well as your cellphone and laptop). Just full charge the battery and shoot tens of rounds, disconnected the batteries and put them in a proper place, then you are good with lipos.

About 20 minutes. You can also use lipo pack's that will last 45 minutes to an hour.

This is a great charger for the price, but it doesn't have a storage mode. Amazon has the small lipo voltage checkers. Buy several. You can set them to go off at 3.7 volts per cell while flying so each cell will be at 3.85 or something close for storage. NEVER DROP INDIVIDUAL CELL VOLTS BELOW 3.0

Thanks Phil. I was concerned that these batteries that are factory pre charged have not been on the shelf for months. There is a limit to shelf life on these batteries.

How do I find out what is wrong with this battery? I did not know that you aren't supposed to use the regular battery tenders on these kind of batteries and I left it charging for a couple of days and now it is beyond dead. So if the tender didn't kill it, apparently (also read just now in the questions section) if it drops below 8% charge it is no longer anything but a paperweight? So tell me now if I should just go out and buy a new battery after wasting my money on the 1 ride I got out of this battery.

I have a special charger for my R/C truck (duratrax onyx) that can be programmed for all types and sizes of batteries, so I don't have any problem with batteries overcharging. I purchased 5 additional LiPo battery packs for the quadcopter real cheap and they work great. The enemy of batteries is the charger - it's worth while to go with a programmable charger for any rechargeable batteries you own. I bought a cheap 5-way splitter to charge multiple batteries for my quadcopter at the same time and it works just fine. But, you need to have a good charger that doesn't overcharge. Otherwise, your batteries will puff up and their life will be shortened. Another advantage of a programmable charger is that the charge time is much shorter. I can charge one battery in as little as 35 min, or around 60 min at a lower mah rating (which will help the battery last longer). Look for a charger on Amazon - you can find them for around $35. I just cut the end off my 5-way splitter and put a plug on it that's compatible with my charger. Just keep the polarity correct and you're good to go. BTW - if you charge multiple batteries, I would make sure each is equally used, ie dead, then boost the mah rating according to how many batteries you're charging at once. I would charge one battery pack at 0.5 mah, but use 1.0 mah for 2 packs. Make sure the voltage is set correctly, as well as the type of battery (ie LiPo, Nimh, etc).

Do not store lead acid batteries. They will discharge over time, and discharging reduces their capacity. I learned the hard way. I bought a new APC UPS and didn't use it for a year. The battery was completely dead right out of the box. Made the same mistake with a portable air inflator. I let it discharge too much between charges and now it can barely hold a charge. Shame on me. Keeping them fully charged, I get many years out of them. I have one that's 11 years old and still working (I don't know how much capacity is has left, but it works).

If you still want to know, buy any brand lipo battery that is 1 cell,3.7 volts, 380 mah. or less. You might need to modify the connectors, but it will work better. If you want any additional power, get a 2 cell 7.4 volts, 180 mah.

Also note that the lipo battery in storage are usually 50% charged or more so after use try to charge before the end of the day either fully charge it or at least 20 minutes in the charger otherwise it wont recharge hence(dead battery)if stored empty for awhile.

is the single lipo battery a 1,2,3,or more cell battery, if it is a 1cell battery you can if it is more than a 1 cell i don't think you can, with out a balance connector.

Dunno if this one will makeyour truck faster, which kind of batterie areu using right now? If u r still on 6/7cell lithiumion go and switch to 2s lipo packs, for thoseu will need a different loader than the standart one, but buying a lipo loader and 2 lipo packs realyisworth it cause with those u will drive for like 45 minutes, charge them in 1 hour and have like 150% speed and power.GreetingsRoger

For the six months mine actually worked it could be mounted anyway you want. I am looking into replacing it as I have a cheap one on my battery pack now. This one really worked well to keep the pack fully charged. Won't be buying another one of these though.

About a year, I think. You need a good lipo charger so you can balance the battery and store properly. It may still be good and just needs a good balance charge. I ran into the same problem with a v912 and the charger brought it back. It is always a good ideal to have a spare battery. Hope this helps.

I'm not trying to spend your money for you, but, you should really try a 2-cell LiPo (lithium polymer) battery pack. It will be like driving a whole new car. I promise you won't regret getting one.
