Eco Tree Drop In Lithium Batteries - Your Experiences?

[Dorset Diver]

Have you fitted Eco Tree, or any other suppliers, "drop in" lithium batteries without altering your system in other ways? If so what was your experience good or bad? Were any problems? Did they work well without issues?

I have no experience with these or any other so called "drop in" battery but I can imagine that it will depend on what you or any contributor already have installed and I am thinking specifically of a B2B type charger which some people seem to suggest is the minimum, it might also depend what you want to do with the installed batteries ie big inverter running 2kw or just TV and lights.

Had mine in since early on this year. Small problem with fuse holder melting between starter battery and leisure battery but fitted a decent quality one and all has been fine..Been away in Frsnce/Spain 4 nights now without hook up and leisure battery sits between 13 .3 and 13.9 most of the time.Compessor chest fridge and telly running off it Got 100 watt solar panel..BUSBY.

i won a reduced price one from oak tree just dropped in no lithium profile on charger or solar so far so good sits at 13v most of the time

I also won mine for half price ,,BUSBY.

I’ve got KS Energy Lithium’s. 2x204A cells so just over 400A total. I’ve literally just dropped them in and relied on KS delivering a good enough BMS on each one to take care of things.

Ive got a 60A mains charger when on EHU and get around 80A with the engine running. Had nearly two weeks parked up in the summer. Ran the onboard gennie for 3 hours during that time.

Next is some solar upgrading to take me to a non gennie off grid setup.

+1 for KS Energy. Neal fitted the battery for me within the quoted price, all done in about 30 minutes on a boiling July day, including testing and setting up the App and printing receipts and guarantee etc. Really pleased!

The BMS on mine, after some investigation, would seem to protect against overcharging. Whilst a genuine LiFePO4 profile would be best, I think its inbuilt individual cell overvoltage protection would work for pretty much any charger that could cope with battery disconnection (i.e. switches instantaneously to power supply mode, or continues at absorbtion charge). I was sceptical of the whole idea of a "drop in" battery, but am struggling to find a reason why the one I have wouldn't work. Basically, I think the BMS would cope with a constant voltage 14.4V charger, let alone something more sophisticated.

Having seen the ridiculously thin cables and cheap pwm controller from my dealer install i slowly upgraded things before my 2 banners were no longer for this world. Started with wiring and chosing a votronics mppt controller with future profing in mind thinking of gel at the time. So up went my 100w panel with the 120w already up there. Bit more time upgoes another 330w (£130) so now add another votronics controller. Batteries die just about to concider 3 gel then seen a post here lithium 100ah ebay less than £500 with bt bms. Quick purchase of b2b before battery turns up.
So would have been a simple drop in if it hadn't been for haveing to modify the cbe battery charge module.
Simple drop in but 2 years in preparation. Ps no mains charger as don't use ehu, so just turn off existing one a low power one supplied with battery.
