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

    Yes that's normal behavior and after dropping to 0 Amps, it slowly goes to 5 Amps again in a few seconds. Because of that I don't think the battery will suffer in any way, but there could be other theories.

    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?

    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

    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...

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

    Thank you so much for your extensive answer! I'm almost certain that the transistor is for the orange light on the charger port. Still have to trace it exactly. Actually I want to test the pack with my Hyperion 16S charger. Do you think I can disconnect the pack from the electronics without it...

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

    I have a BionX R320/R420 RIDE+ battery (01-3852) 48V/6.6Ah 316.8Wh. 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 few minutes...

    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)...

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

    I think you're right. I just bought one on eBay and I'm very happy with it.

    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...
