Re: New Chargery 1500 24s charger

The C10325 is a great charger and works fine stand alone. I liked the feature set, though menu implementation and the connector were kind of annoying. However, fried it this morning - I was running it in power supply mode charging 14s Leaf pack at 10A, and when BMS disconnected the charger due to p...

Re: New Chargery 1500 24s charger

I still sell a few, but there are other dealers now. The C10325 is a great charger and works fine stand alone. The C4012 is not a "bad" charger either, but it suffers from the same limitations as other balance chargers. Balance current is around an amp, so it must cut charger current way back when a...

Led tester/ 27v continuity/ 30ma source

I built similar with a switch to change profiles in DeltaQ chargers. It has become so useful that I made one without the switch. Testing leds was a two person job. One to push the switch.

Re: Salvaged EV cells index: Leaf, Volt, Tesla, Zero, etc

Newer may be better. I could just squeeze a little over 60ah out of the ones I tested.
Which is fine, however the seller sold them as 75ah.
Oh, and they were new. Maybe needed cycling to come up. :?

Re: bluetooth BMS?

Pretty unlikely the first and last cells are bad or charging faster.
Look for common impedance in the power wiring and balance leads.
R1 and R2 will make first and last read high.

Got a new rca tablet. Still can't connect bms or vbms.
I did get HYD to connect. I like that better in any case.
The Chinese version always connects, but has other issues.
