100Ah Lithium Battery For Sale

[wildebus]

I am selling one of my Poweroad Infinity Subzero Batteries.

Info on Battery:
This is a 100Ah Battery (internally actually approx 108Ah) and instead of just having a simple BMS that stops any charging at below approx 5C, the Subzero battery has an intelligent BMS that controls more precisely how the charging operates (see the attached flowchart), allowing the battery to charge at lower rates below 0C, and at higher current, use the built-in heater to warm the battery and allowing the charge current into the battery in stages.
In colder weather, such as we have now and will have until Springtime, a Lithium Battery with a standard BMS and no heating function may never charge if in an external locker (or even inside in an unheated van).

Battery Serial Number: PRHEATLA300321C180029 (Bluetooth number in screenshot is the Battery BMS Number)

Integral Heater within Battery Box.

BMS: 150A BMS with Bluetooth Interface

Cell Type: Pouch cells

Weight: 12KG

External Data Interface: RS485 & CAN

The battery state can be interrogated via the Poweroad App on your Phone or Tablet to check the State of Charge and cells. The following are some screenshots from earlier this morning:

Initial App Screen:


Main Screen showing State of Charge, Battery Voltage and general Status


Detail Screen showing Voltage, Current (and if charge or discharge); Individual Cell Voltages; Temp; and Lifetime Cycle Count

This battery has only had 15 charge cycles in total, and as can be seen the cells are nicely in balance, with just 0.004V (4mV) variance between highest and lowest.

It is designed to be a drop-in Lithium Battery, and with the Bluetooth Accessible BMS data it genuinely is as long as you have a Lithium Compatible Charger (or use one of my Wildebus Lithium Controllers if using on a Hybrid setup)

I have been using this as (and is still right now) part of the Lithium/Lead Hybrid Battery system in my Motorhome (see here for more info - https://www.wildebus.com/hybrid-battery-bank-introduction/) but I want to now test out some different batteries, hence why this one is up for sale

Looking for £480 for this hardly used (just 15 charge cycles remember) 100Ah LiFePO4 Battery with integral heater and Bluetooth BMS with 150A Current Capability.
Most Lithiums have no heating ability, no accessible BMS and a 100A Current limit and cost more than this one!

yes please david subject to them being suitable to my system of course, been prevaricating over lithium for last couple of years if put in conjunction with a lead carbon battery would there be any of the issues that lead acid have ie both of same age wear & tear etc

I don't think it would make a difference ref age. I think it would actually even be a good way to get further life from a more-used set of Lead batteries.

You would need the Lithium Controller as well as the battery if you want to use as a Hybrid (that is an extra cost just to clarify) but I have found over the last approx 9 months of running Lead-Carbon and Lithium that the two in combination work very well.

i would just drop yours in for now ( hopefully of to spain in 35days) think on the hymer it’s a straight swap just altering the setting ? then get the hybrid sorted on the return how much output via inverter would that give & is the battery portable hermes etc or does it need specialist delivery

The good thing about the Lithium Controller is that it means you don't actually have to do anything with the current charging setup on the hybrid setup.
If you want to just do a swap over as a temporary basis then setting the Hymer to Lithium or at least GEL is needed.
Reckon on taking around 80Ah out of the battery as a discharge target to give a little in reserve (I have taken over 200Ah out of the pair of 100Ah Subzeros a couple of time - they are certainly ok for full discharge when you need the whole lot). BMS rated for 150A which means an Inverter of around 1500W.

Specialist Courier needed, yes. I can get a price for this (I'd use the same one that Alpha uses).
