Discussing truths and myths around deep cycle lithium batteries for caravans, campers and 4WD's with Pat Callinan from 4x4 Adventures. We also address the difference between quality lithium batteries and other inferior brands.
One of the biggest short coming of lithium rarely mentioned is their reduced charging rate at 5'c or less if using a quality charger that has inbuilt temperature sensor. Yes they still discharge at full rate but charging is reduced. I see overseas heating pads are fitted to battery to enable charging. I have come across this issue in New England area of NSW, Victoria alpine area and southern Qld border country. Been using Li for 18months and will nit go back to AGM for my 4wd
I had a heat pad on my old Lifepo4 pack but the new blue tooth BMS have low temp cut offs - a trick i learned from a Norwegian fiend is to put a load on your battery will warm them just enough so they accept a charge if its frosty - I moved my battery indoors under a seat as it does not need to vent like lead acid
@@trevortrevortsr2 The battery is mounted on my 4wd. Unless load up my 600w inverter I would struggle to draw 8-10amps. I have enough storage that in cold weather that charging every 5days is required. I could just turn on the PV full time so it is charging slowly and still stay above 20%SOC for over 7days I suspect. If Covid does not stop me travelling will be spending a month in Victorias ANP and find out in practice
Run these batteries in both 4wds and campers. Absolutely brilliant, and yes there cheaper out there, but you have you understand what your usage and requirements are for continuous usage. Example friend runs a Enerdrive 200amps, works great for most applications. Then try run a aircon or induction cooker. Just hammers it in no time. Same test on two of these continuous orange tops in parallel; and we get near twice as long. Charge time is another thing, these are crazy quick. Just magic!
that's interesting, I was wondering where the enerdrive fit into the scenario, as there are heaps that seem to run them. different levels of performance reflect the levels of price sometimes. Hadn't heard the C rating mentioned before, so that's interesting as something that may create the difference in the comparisons.
