Anyone have any info or have these new BMS ? I like the look of them. These signallab ?
I'm going to mail ping and ask if you can buy these seperate like he has sold me before.
Sorry if this is a dupe did a quick search found nothing.

This is cut from that blog link.

What's new on V5 LiFePO4 BMS

New design for good heat sinking. The big black aluminum heat sink plate is mounted on all the big IRFB4110 MOSFETs and bleeding resistors. It will be very cool when the battery is being discharged. At the end of charge, the heat sink plate will send out most heat from the bleeding resistors. Furthermore, the design of heat sink system is compact. It's only a little bit thicker than the elder version.
All V5 BMS have IRFB4110 MOSFETs, even on 24V or 12V LiFePO4 battery packs. Yes, all the V5 Lithium Ion Phosphate BMS have this famous and strong MOSFET as intelligent on/off control. The standard BMS has four IRFB4110 in charge of discharge and one in charge of charge. The high rate BMS has eight IRFB4110 in charge of discharge and two in charge of charge.
Since IRFB4110 is rated at 100 volts, if you connect two battery packs in series and the total voltage won't be higher than 100 volts, you won't need to connect protection diodes in the circuit. For example, with elder version of BMS, if you want to connect two 36V LiFePO4 battery packs in series for 72V, you will have to connect two diodes in the circuit to protect the two BMS. Two 36V battery packs with V5 BMS can be directly connected in series without any problem.
Lower power consumption. The powering circuit on the BMS was redesigned. The power consumption is much lower than V2.5.
Different power source. The elder version of BMS or some other BMS in the market are powered by the lowest 4 series of battery cells. The V5 BMS is powered by all the cells. This way, the battery pack won't be imbalanced even it's not charged for long time when BMS is connected.
Bigger LED indication. Instead of SMD LEDs on V2.5 BMS, we use bigger LEDs on the new V5 BMS. It's clearer for users to check if there're any of them haven't lit up at the end of charge. None of them will be missed.

Good, no more melty holes in the shrink at the fets.

Yay! No more burning out the cheap HY1807 FET which warps the PCB and can let the cells overcharge causing damage to the pack. I was already a victim of this once. Only bad thing is these boards are guaranteed to cost more. His 40A V2.5 boards were less than $50. Let us know how much these cost.

Response from ping below.

Hi Stephen,

Price of 12s high rate BMS is 80usd, 20s high rate BMS 96usd.

Shipping cost of two high rate BMS to the US is 25usd.

Of course, I don’t mind. We have announced V5 BMS on the web site. It’s not a secret now. Thanks for letting those guys know our new product.

Best regards,

Ping

I am sure it's just a snap in replacement. I will ask him and respond.

Hi Steven,

Yes, you can use the same balancing cables. The connectors are compatible. You just need to swap wires on B-, P-, C- and sense wire connectors.

Best regards,

Ping

sure is. we are getting the the 24S D131 for $53 each in this group order and were able to specify the 4.18v balancing voltage.
