Ben and Alana were very helpful. Thanks again and so far our battery has been going for 15 days and hasn't used any juice at all. We will be taking it for the ling weekend camping where it's a little colder then we will also fund out how ot works when it's a bit colder.

Recently installed 4 of the 100Ah Polar Series battery in our van. So far the batteries are discharging and charging as expected. The BT app works well to display detailed battery info. Ben was great to deal with and provided useful technical info to support our install.

The battery shipped and arrived on time as expected. Because of the small case size (much smaller than some competitors) it fit in a standard dual 6v battery box with room to spare.
I swapped out my WFCO converter to Auto Detect (lithium detect) unit prior to install.
With battery at 51% as shipped it took 10 hrs to 100% likely due to WFCO not seeing lithium as charge voltage was 13.8.
I recommend getting one with Li switch or jumper setting to be certain.
Nevertheless, it hit 100%.
I then enabled solar charger set to Li at 14.4V which should supply Li charge voltage regardless of shore power charge.
I use 2000W PSW inverter, ran 1500W kettle with battery voltage staying steady with no dimming of interior lights.
So far so good.
First boondock trip test coming up.

Been using 200 AH Polar Series for 6 months and they have been fantastic. They replaced 2 6V AGM that came in my MH. These batteries are top shelf prismatic cells with a quality BMS, which provide fast charging and balancing of cells. I’ve only seen the BMS in balance mode once when battery’s were new. Every time I’ve checked with app they were within 0.10 V. Highly recommended and a great value.

Fantastic customer service from Ben - he reviewed the specs of the solar system on my RV and was able to confirm that it could handle a lithium battery. I bought the Polar Series 200 Ah battery and it was delivered fully charged within days. Looking forward to the camping season!
