| FlightPower battery, Slight fault! hello all, While flying my hyperion sniper today, i basicly found that one of my (new) flightpower 1200mah 3s1p batterys seemed to have a wiring fault. If you wiggle the wires...power is cut off from the battery...wiggle it again (sometimes a lot of wiggling) and power is restored. At first i thought it was my soldering on the deans connector (most likly suspect)...but that looks fine. I suspect the fault is inside the battery, where the wire solders onto the cells. Any one know where i stand with returning this item (as of yet, i cannot find the reciept) or how safe it would be to try and repair it myself?

| FlightPower battery, Slight fault! Be very careful with this pack. A loose wire on the cell terminations could lead to a short circuit which is dangerous with a LiPo (risk of fire etc). I would place it in a fire proof container while you decide what to do. | |||

| FlightPower battery, Slight fault! Very true Alan, Its currently sitting in its own Lipo Fire Bag, in a metal sink. However... I went flying again this morning, and i had the same problem, with a different pack! So now i suspect it could the the ESC. Im going to crack my multi meter out in a moment and do some testing. For 2 batterys to be duff seems very unlikly. Although...you never know if there all part of the same duff batch!?

| FlightPower battery, Slight fault! There really isnt any point messing about, just send them back to Flight Tech (Energon Solutions ltd)and they will no doubt replace them in a flash providing they are faulty, and it sounds as though you dont really know yet! However if they are flight power and not flight tech, then they are not really new they have been around for a bit so they might have been old stock from some one. Planes are meant to crash, otherwise they'd have feathers | |||

| FlightPower battery, Slight fault! Hi David, I thought i had updated this thread but obviously not... I did some testing and it turned out the fault was with the deans connector. Ages ago i bought some quality deans and some cheap deans, it turns out i had soldered a quality deans to the ESC, and 3 out of 4 of my lipos had the cheap deans soldered on them. When the two deans are connected - theres a slight difference in colour and shape of the connector. But the real problem is the connectors inside the deans...flex the connection just a tiny bit and the pins inside would move in the cheaper dean. I have replaced all the bad deans and since not had a single problem! So there you go, although a bit expensive buy the quality deans.
