Seeking a lifepo4 charger/discharge test for 8S (24V) batteries.

[matt2006]

Hello my fellow smart people.

I buy these K2B24V10EB from a ewaste recycler; and I test them.

I have been using the iCharger 3010B as they can do up to 10S AND they can do regenerative discharge which means I'm saving all that energy that is coming back out of the batteries.

The problem is I have to have a laptop to display and every few months the USB connection to COM and the charger stops working for whatever reason.
I cannot buy more of these chargers as they're no longer manufactured.

SO; seeking an alternative charger/discharger that meets these requirements:
1. Can Charge/discharge 8S minimum lifepo4
2. Will display mAh on its screen and not go blank if the battery disconnects itself from low voltage cutoff in the BMS

IDEAL but not required:
3. REGENERATIVE discharging

4 Banks would be cool as well

Clones of icharger 3010B:
Charsoon Antimatter
HOTA Thunder
Turnigy 1000W

Dual channel charger nearly the same as 2X 3010B (30A, 8S):

iCharger 308Duo

High-power charger providing 30 amps on each of two channels - or combine the two outputs in parallel for up to 50 amp charge rates!Includes a JST-XH balance board for each channel!

An absolute monster, more power than 2X 3010B (You can even get 70A by pairing the two channels together):

iCharger 4010Duo

High-power charger providing 40 amps on each of two channels - or combine the two outputs in parallel for up to 70 amp charge rates!Includes a free JST-XH balance board for each channel!

Other 8S/regenerative:

iCharger X8

The X6 has a big brother! Don't worry though, it's not much bigger physically - but it does up the charge stakes significantly, with 1100W of potential output and capability to handle packs up to 8S.

ISDT Q8 Max

Tiny. Powerful. Affordable. Unreal.

Thanks a bunch!
I have ISDT Q8 but it doesn't read voltage right; i do a 3a discharge and it locks in at 0.4A which is not acceptable.

I bought the 4010 duo but may return and just go with 308 duo to save costs.

Do you know if the 4010 has better features that make it worth it?
If only the input went up higher than 50v; a littler higher and you could use a 48v lifepo4 bank to power it.

It's just higher limits (power, 40A/channel) and the ability to go to 70A dual channel on one battery.

Here's my new test bench with a 4010Duo and 308Duo



NOW I have 4 of these iCharger 3010b I don't need;
is anyone interested to buy? Retail was $100 each

WHAT??? DON'T NEED???? Now you just need to make more space for testing.

There happens to be a space shortage!
