1) You will need a Li-Poly specific charger to charge the pack (NiMH or NiCD only chargers WILL NOT WORK!)
2) You must not over discharge the Li-Poly battery pack.
3) Read the instructions carefully before operating this battery.

NOTE: When using high energy Li-Polymer Batteries, please do not over-discharge or over-charge batteries as this will result in over heated batteries. Discharging capacity can't exceed 80% of the max capacity of the pack after full charging to ensure a good cycle performance. It is recommended to fully charge a brand new battery before using and only discharge the battery 50% for first 5 cycles. Always monitor flight time and/or set a low voltage warning on ESC (End voltage cannot be lower than 3.2v per cell) Do not use the battery that has too low a voltage.

Do not expose batteries to sunshine or store/charge batteries at the temperature above 35°C or in a closed car. The high temperature environment could cause damage to the pack or make it burst. If the battery becomes hot while fast charging, high current discharging or racing, do not charge the battery until it has cooled completely. Wait about 20 mins, then inspect prior to recharging.

If you peel the lable off they fit fine but the connector sucks. Out of four of them only 1 works as it should. As far as it being a good battery, they hold up better than the E-Flight batteries. If the connectors worked better I would give them 5 stars.

I bought two of these batteries for use in my Blade MSR helicopter. It works OK, but it's a very tight fit in the battery holder and the connector does not mate well with cable on the helicopter. I've struggled to get it connected prior to flights and had it fall off on crashes and even in mid-flight. I think it would have been worth spending a little more to get the OEM battery.
