Battery vs. battery

[Aussieguy]

Balancing...
The cells inside a battery WILL become unbalanced as you use it
that is normal ... you can see it when you use the app.

Balancing will start at defined point and the BMS will handle that... you don't have to do anything except to ensure you battery is charged long enough to finish the charging.

If you rely on solar for charging.... you need enough panels to charge the replace the night before battery discharge. If your panels are small or it's raining turn off some 12v loads ... a COLD fridge can be turned off for a couple of hours , just don't open the doors a lot while OFF.

Generator... and converter
make sure the converter is actually sending good amperage to battery.
The bluetooth BMS will tell you how much charge the battery is getting
If you got a 55amp converter but never see more than 10-15amps getting to the battery then your converter to battery wiring needs attention.

Shorepower and converter
most people on shorepower are hooked up all night... which gives you plenty of time to fully charge and balance

Once you get use to the battery and APP you will feel more confident... you'll see that it is working ...
For Balancing just make sure when battery is 100% and not doing anything the indivdual cells are close to the same voltage. They MAY never get to exactly the same

I was looking at LI Time but did not see one w/Bluetooth. Did you find one?

if you got amazon prime ...
they having Prime Day sale
Login to your Prime account to see prices

search amazon or google ...... Lifepo4 bluetooth Litime

https://www.google.com/search?client...uetooth+Litime

https://www.amazon.com/s?k=lifepo4+b...f=nb_sb_noss_2

I have Elfhub bought from Amazon they are working well .... about $100 LESS expensive and have traveled 3000 miles with them
they are cycling to about 75-80% every night then solar tops them back up each day.

Or just go to the Li Time website. Here's a BT model with low temperature protection...
https://www.litime.com/products/12v-...mart-bluetooth

The price on the Li Time website appears to be $50 cheaper than on Amazon.

The Litime website is where I saw they are advertising Prime day deals?

A few factors come to mind. Chinese manufacturers do very good quality control for some companies, rejects going to other Chinese sellers at lower prices with different brand names. Some Chinese manufacturers just make cheap junk by skipping features and using inferior parts.


How to tell between good and bad? Your guess is as good as mine, but buying from a reputable seller that offers a great replacement warranty is a start.


Look around at reviews and guys that make their own battery packs.
Good luck.
