Quick one you wizards, I’m looking to go Renogy Core 100ah with victron shunt as the battery doesn’t have BT, is the low temp cut off enough protection (0 degrees according to renogy) or is battery heating a must?
Lovely jubbly cheers buddy.Heating is completely optional - low temp cut off is a non-negotiable, either via the battery BMS or your chargers.
No heating just means you won't be able to charge the battery when it's below zero. You can still use the battery when it's below freezing - discharging is fine - charging is not.
You'll need to have low temperature cut off set on all your chargers, which may be easier on some than others. NEVER charge a standard LifePO4 battery when it's below freezing.Hi All, just need some help in fitting a new battery, 51 pages is alot of reading! I have just bought an ecoworthy 100Ah LiFePo4 battery, i have a 2017 T6 and it has a Sterling
Power B2B fitted as per picture below and it has the LiFePo4 setting available, I also have the Victron battery charger 12/15 and the Victron Mppt 75/10 on my portable solar panels which both have the LiFePo4 setting. so my question is what else do i need and how am i best connecting the wiring to the terminals?
Thanks Sam
Yeah I've read that, i fear I've jumped the gun a bit and should have spent a bit more on the battery which had it all built in. Im probably going to have to spend more now to get it set up suitably.You'll need to have low temperature cut off set on all your chargers, which may be easier on some than others.

To rub it in, the new Fogstar Drift ECO (without BMS or heater but with low temp cut off) is only £30 more than the lowest the ecoworthy battery was...Yeah I've read that, i fear I've jumped the gun a bit and should have spent a bit more on the battery which had it all built in.

Think i may have to change my B2B as well due to its size!
Got major buyers remorse now!

Check which model of Ecoworthy you have. The newer ones (seem to say 4000 cycles on the side rather than 3000) appear to have cold temp charge protection on the BMS. The German ones also have Bluetooth but they aren’t on the UK website (when I looked a week ago).Yeah I've read that, i fear I've jumped the gun a bit and should have spent a bit more on the battery which had it all built in.

Yeah it has 4000 cycles on it, so that’s slightly positive!Check which model of Ecoworthy you have.

A shunt is much, much more accurate as it measures the actual power going in and out of the battery to calculate the percentage left. The BM2 you have just makes a guess based on voltage at the time which will vary depending on draw or charge. They are almost pointless for a lifepo4 battery. The Victron Smart 500A shunt is good and works via an app (no screen).I've messaged them to be sure. So if its got low temperature protection, i should be ok as my sterling charger doesn’t have a low temperature protection, i guess i could fit an isolation switch between battery in the charger? Do i need to get a shunt so that i can monitor the battery information? I have a bluetooth monitor thing already:View attachment 257418
