Blade SR Battery Charging Question

[WhiteCloud]

hope someone knows the answer to this, but, i just ordered a blade SR, the instructions say not to use an after market charger to charge the battery because of circuitry on the battery........has anyone tried using an after market charger? were there any problems? i just would hate to have to use the stock charger if i don't have to, thanks for the help

Soon after I got my SR, I got a smart charger and never had a problem. As long as it is a lipo charger and you select the right number of cells and the correct current, there will be no problem.
There is nothing special about SR batteries.

I also have a blade sr (2 actually) and as long as you have a good balancing lipo charger and select the proper voltage and current you should be fine.

It actually says not to use an aftermarket charger? That is strange.

Battery Charging

It is important that you only charge the included 3S 11.1V 1000mAh Li-Po Battery Pack (EFLB0997) with the included 3S 11.1V Li-Po

Balancing Charger (EFLC3105). Your battery pack is equipped with special Charge Protection Circuitry and a Balance Charge Lead with

connector that is only compatible with this charger.

CAUTION: Attempting to charge the battery pack using another Li-Po charger or non Li-Po compatible charger could result in personal

injury and/or property damage. Please familiarize yourself thoroughly with the Battery Warnings and Guidelines section

before continuing.

Well I'll be! I've charged stock batteries, (2 of em) with my imax B6, since I've owned em.
No problems. I usually fly using either my Thunder Power 1350, or zippy 1000 compact though.

I've had two of the stock chargers fail. One ruined a battery, the other just didn't work right from the start. So i bought the 200w eflite charger and the eflite power supply. That eflite charger stopped working too so i finally bought an icharger 306B. If it is electronic and says eflite, its junk in my opinion.

That's the sort of things I've heard about the stock chargers.
Is why I left it still packed in the box when I bought the heli....

thanks for the help guys!

i have a Hitec Touch charger that i have been using for a month or two now and i am pretty happy with it, easy to set up and use, so thats the charger i am planning on using, but when i read that paragraph in the manual i got a little nervous on trying to use it but you guys mention that you are using aftermarket chargers without a problem then i feel pretty safe. again thanks for the help

It'll be fine, but always keep an eye on any Lipo
your charging, they can explode, and cause a fire..

i tried to charge my SR battery on my Hitec Touch charger and it errored out, it said no connection! so, i am left with using the provided stock charger

i guess the instruction manual was right

I have an Imax B6, and a Venom pro charger both of these charge not only my E-flite batteries,
but my Thunder Power, and Zippy compact batteries....you might want to check the connections somewhere, your charger should charge it.

[jbilliter]

+1. The stock charger charges through just the balance connector. But smart chargers probably all require both the balance connector and the main connector plugged in because they do further checking that everything is proper before continuing. I also had connection error till I plugged in everything.

[nighttrain06]

Ahhh yes I did same thing when I first started using a better charger forgot about that....
Check that you have both ends of battery plugged in WhiteCloud, and always try to use
the battery balance charge function.....it's better for your battery.......probably should get
a battery checker also.....one of my chargers I found was giving me a false reading also.
It would say 4..20 per cell, when actually it was 4.21 when finished charging...so I always
have to cut charger off if I use that one at 4.19 per cell.

[WhiteCloud]

here's the part that i don't understand, when i charge the SR battery on the stock charger the charger only uses the balance plug, and when i charge my mCPX BL batteries (which only have one lead) the charger has no problem with it. i did have a connection error on the charger when i hooked it up the same way as the mCPX BL batteries??

how do i hook up the charger if i am charging multiple batteries at the same time? i.e. parralel charging?

[nighttrain06]

Are those batteries on the MCPx lipo's?
I'll assume your setting up charger to lipo's,
I may be wrong but I think you need a parallel
Charge board to charge multiple battery's,
And there should be leads to connect the Red
JST connector to as well as plugging in your white
balance plug so you won't get an error, also
You may have to set up charger for that battery...
ie.....11.1 v 3S and if it's the stock E-flight battery you,
Charge at 1.0 C...

[jbilliter]

I think the charger doesnt check both connections when you select 1s. But when you select 3s for the SR batteries, it checks both connections. As far as I know to charge multiple 3s batteries you need "Y" cables or something similar which split out the balance connector to multiples and split out the main connector to multiples. BuddyRC.com sells a large selection. Here are the cables I use to parallel charge 3s batteries:

[WhiteCloud]

i don't think i explained it right, the mCPX BL uses a 2s 200mah battery, when i charge the batteries i connect several of these batteries to a board which hooks to the positive and negative plugs of the charger, it also hooks to a balance board connected to the charger, this works without a hitch every time, but when i hook the SR battery to a 3s board which also has hookups to the positive and negative of the charger and a hookup to the balance board it errors out on connection error??

its the same hookup procedure, thats what i am confused about

[jbilliter]

Well it sounds like you are doing it right, and it should work. Make sure the connectors are well seated and no wires are loose. It could be a bad parallel board.
