Thanks Steve for the heads up. I will replace the lead acid batteries even though they are Advanced glass matt with the new Lithium iron phosphate replacements coming on the market. it will save up to 40 kg in weight and the electronics in the lithium batteries mimic the charging sequence of the Pb AGM. One more question, I have not yest used a CC2 DC fast charger that the I - Pace can accept, do I need to purchase another cable for this charging point. Many thanks for your prompt reply.Hi Stuart, welcome to the forum.
In Australia the Tesla destination charger connector is compatible with your I-Pace, some sites will work but the ability to interface with the I-Pace may be inhibited and only work with Teslas. You can "enable" the PlugShare App to view Tesla destination chargers. If you select a Tesla site you can scroll down to view "Checkins" and read comments from owners of non Tesla vehicles. Comments of "Could not Activate" will tell you that site is locked to Teslas only.
Re the 12V battery, there are two 12 Volt batteries in your I-Pace, they are located under the removable panel under front hood. I replaced the larger "Start Battery" with an AGM battery to match the small "Auxiliary" AGM battery. link below.
Here's a quick primer on charging the I-Pace, anno 2020 Nominal battery capacity is 90kWh, but there's a bottom and a top buffer of actual use, and a top and bottom buffer for displaying 0% to 100%. For purposes of discussion, I'm going to round things off and assert that there are 80kWh in the...www.i-paceforum.com
The I-Pace charging system is optimised for AGM batteries, when JLR built the car they installed a cheaper battery used in small Jags and landrover vehicles.
I have installed Matson bluetooth battery monitors (from Supercheap) on each of these batteries, very happy.
Hi Stuart, the larger "Start" battery is not an AGM battery, it has a much lower float voltage that can be observed v.s. the "Aux" battery after a charge event.
Please post details of your Lithium battery install, when you get the job done.
Those Matson monitors I recommend will give you an insight on the parasitic loading on the the larger "Start" battery v.s.the "Aux" battery. You would probably be able to view the lithium batteries balancing after they have been charged too.
My replacement 55Ah AGM battery is approx 16 Kg, it replaced the original 47Ah wet cell one, the Aux AGM battery is only 15Ah capacity. The Exide battery equivalents are EA472 and EK151, you can search for the dimensions online.
CCS2 DC chargers have the correct connector plug and heavy duty cable, chargers capable of over 100Amps have heavy water cooled cables to stop the connector pins overheating.
Steve, what brand/model of AGM did you buy to replace the Startup battery? Were the terminals a match to the original battery?My replacement 55Ah AGM battery is approx 16 Kg, it replaced the original 47Ah wet cell one, the Aux AGM battery is only 15Ah capacity.
