I was thinking of doing 2 of these pack's in series for a Razor MX650. would be pulling 3C max I read not so good things in teh RC world about these pack's but i assume they are running them are 30-40C aand would be the reason they puff. My question is would they do that with the amount of C i will be running? I would like a pack to last me as longs as it can charginf would be some where around the 5-6 AMP range so would be less then 1C charge rate which will help make the batteries last longer. I will chanrge each pack independent of each other.
A low current draw and a <1C charge rate will make your batteries last a long time but if you won't be using them for a while keeping them at storage charge (3.8v/cell) in the fridge will make them last for years. Time plus heat will kill a lipo's capacity by up to 40% per year.
Is it okay to charge this Lipo with 5A Lipo charger? Have a cheap charger that 5A is max. Do I have to buy a new charger?

Well according to the rule of thumb the batteries requirements is set at 8 amperes. HOWEVER! if you decide to keep charging it with your old charger! the that will really extend the life of your battery! Now please don't forget to set the battery to store charge b4 you put it away for the week or the winter! other wise you will have a balloon in stead of a battery! I have to learn that the hard way!
Because my 5A charger become so hot I have decided to buy a new bigger charger for this big battery. Is there any good charger that has the sensors needed for safe charging so I can just plug it in and be happy? Can you explane what b4 is and how I shuld store it the best way?
Well I have an Hyperion! it connects to the computer and allow you to charge anything under the son! but you need to make sure you have a nice and juicy power supply, I have a 28V /24 Amps! this allow me to do any thing that I may want! but truly the sweeter thing about it is that you can set setting and programs for every single battery! Example will be wen you charge 4 lipos of 14.8v each at 3000 Milliamps! you can make sure that your amperage at this point 12 amps is set properly, basically there is no limitations to what kind of battery you can charge!
i bought this battery and a charger- balancer to be used on my E-scooter. the scooter worked with acid battery untill now.
do i need to buy some kind of a controller\defence_circuit for it (for example- to cut the power when the cells are under 3V)?
if so- can anyone tell me what exacly do i need?
can the pack weight please be comfirmed by anybody who perchased one
1 thumbs up!
Com esta amperagem... Vai ficar voando bem mais que eu imagino... Otima marca... Tenho no meu TREX600E de 5800mAh e voa muito bem... Vou esperimentar essa no meu TREX700E 3G... Tomara que caiba no heli!!! Recomendo a compra deste produto!!!

I use two in serial on my e-bike.
VMax = 50km/h and I can cruise @38km/h for at least 50km.
Recommander for this kind of application !

I bought two packs of this. One is OK, other one has one cell died (0.3V). HobbyKing® Lithium Polymer Battery Warranty Policy say :
1) You can only make a claim for 'Under voltage' the same day the parcel arrives and prior to the lipoly pack being charged or cycled. 'Under Voltage' means that 1 or more of the cells in you pack has a voltage lower than 3v per cell. After the battery has been cycled or used, no claim for 'under voltage' can be made.
It mean, that You can buy the battery, and after purchasing You absolutely can't nothing to do, otherwice warranty don't cover Your product. Great, HK!! It's genious!!!
Think twice, guys, before purchasing so expensive packs...

I purchased several of these and they all arrived close in voltage on each cell.
They have heavy 8awg wires that will help handle heavy loads.
This is a big battery, but for the right application it is worth the extra weight and size over lesser mAH 6s batteries.
I woudl have given all 5's in my review but since I have yet to charge and use the battery I cannot give an honest perfect score.
I will follow up after I use the cells a few times.
