Somewhere in this thread it's discussed.Or balance them separately every month or so and just charge the set without the balance leads in between.

Is that a good idea? Its most likely to happen when you hit the throttle hard, which could be in traffic when you need to move.tppacks said:The LVC function provides an opto-coupled 2-wire output signal that can be connected into the ebike controller's ebrake input, or can be used to pull down the throttle signal, that goes active anytime a block of paralleled cells goes below 3.0V, for LiPo, or 2.1V for LiFePO4. This will cause the controller to temporarily cut the throttle input, which removes the load. Simple, but very effective and extremely reliable.
I've got a 14s pack I've been charging in series without balance for the last few days. So far no problems. I keep checking the balance and it's never more than .02v out. I charge to 95%. Just make sure than the number of cells selected is right. Most times without balance it sees my pack as a 13S pack. That would just give about half charge. But don't go over. That would be disastrous at 4.5V per cell.wineboyrider said:I am waiting on some balance jst xh connectors to come from HK and I was wanting to know if I can charge with 11s or 12s lipo without balance wires????? I just want to charge it for now and hook up the balance wires when they get here?

In the setup select LiFe battery type in one of the memory configs, set cell count to 14s. Parallel your balance leads and bring them out on two 7s connectors. Hook those and power leads up and start charging.hillzofvalp said:how would one go about practically charging and balancing a 14s5p pack of 26650s with the hyperion 1420i?
The charger comes with an adapter board . I bought 2 7S JST-XH pigtail cables and used them.hillzofvalp said:I figured it was as simple as that. Does anyone know the correct pin insert for the 8-pin hyperion balance connectors? I have the connectors but no pins.

Many times when I was using a PC PSU for a 12v power source. Fix is to lower the amp charge setting, or get a better PSU. Haven't seen this once since I hooked up a 24V 600W PSU. Using the PC PSU which was supposed to be 36A 12V line, I had to set the charge rate to 1A iirc to charge the whole 14s pack without error.Philistine said:Curious if anyone else has had this problem. I have two of these which I use in tandem to charge my 20S4P pack which I split into 2 10S packs to charge. One of my chargers has started to do this thing where just before finishing its balance charge, it stops, and gives a beeping sound with the error message "Battery connection error". Wondering if anyone else has had this happen?
I've never heard of 14s being a problem with a 48V controller, The problem arises with 15s. 14s charged voltage is 58.8V, which should work with any 48V controller. 15s is 63V, which will probably blow some 48V controllers that use 63V caps. 13s is about the same nominal/charged voltage as 4 sla 12V batteries, but it doesn't make much sense to me when 14s works fine.Partycat said:As has been mentioned a few times 14s is pushing it for some stock 48V controllers, so, I guess for the purposes of this 12s is much more suitable, and for those who want to play, buying out-of-the-box type equipment is just a luxury and probably not particularly marketable.

Hello Gary,
I noticed its pretty simple to charger 12s 4p and be safe with LVC using your hairness.
Is there any easy way to do 18s without getting 2 hyperions?
Thanks
Partycat said:Do you forsee much difficulty with doing this and using parallel balance Y leads on the LVC board to bring it up to 40aH with 16 packs of 6s/5Ah? Obviously some clarity on the cell reading is lost when you do this, but, you are expected to monitor the cells anyways. Not to mention it would take ages to charge but still.
