Re: BionX R320/R420 RIDE+ | over-voltage/temperature

Is there anyone who knows how much ohm the NTCs / thermistors in this BionX battery contain? I measure less than 5 kohms (in the active circuit) for each of the 4, but many standard NTCs are 10 kohms?

Re: BionX R320/R420 RIDE+ | over-voltage/temperature

I'm also balancing the pack now with my ISDT BG-8S.
The Pack was imbalanced with +/- 100mV. (is this still ok?)
Maybe later I will charge it to arount 54V with my external Li-Ion charger.

All the time I keep the pack connected to the electronics-board/BMS, just to be sure

Re: BionX R320/R420 RIDE+ | over-voltage/temperature

I'm a little further in the testing-proces... There is a resistance of 13.4 kOhm between the ground (first wire of the flat cable) and the second wire of the flat cable. This was broken and indicated completely different values. I put a new resistor in between, but unfortunately the battery still st...

Re: BionX R320/R420 RIDE+ | over-voltage/temperature

The only thing I can find that is really broken is one really small resistor (SOT-323?) with the marking 1P5. This *might* help, but it doesn't always. https://www.sphere.bc.ca/download/smd-codebook.pdf Also I wonder if this component is not just to light a LED. Does it trace out on the circuit boa...

BionX R320/R420 RIDE+ | over-voltage/temperature

I have a BionX R320/R420 RIDE+ battery (01-3852) 48V/6.6Ah 316.8Wh. 20190819_121906-2.jpg Now when I charge it, I hear the 2 beeps, the orange light is not lighting-up, but the Green light is lit continually. I see power is going in (the charges takes 70 to 90 watt, but is it stops charging after a ...

Charging Bionx 48V C420 RIDE+ battery with DC-DC Step-up Step-down Converter

Since I don't have the original charger (BionX RIDE+ 3.45A Trek G2 charger) and I don't want to pay $100,- for a new one, I'm wondering if I just can use my 'DC-DC Step-up Step-down Converter' (with constant voltage(CV), constant current(CC) capability) with the right (round with yellow edge) connec...

These were discontinued like 4 years ago right?
I think you're right. I just bought one on eBay and I'm very happy with it.

Re: Hyperion EOS 1420i NET3 14s Balance Charger...

Hey Guys. I'm looking for some advice about my charger. Today I left the charge-leads and balance-leads to my 10S pack connected to my Hyperion 1420i Charger, while disconnecting the input to the charger. Very stupid. Also the manual states that this is not a good thing. Looks like the charger on it...
