[@obikedog]

I see that battery's recommended charge current is 25A and maximum is 100. Even that recommended current is probably not ideal for life of the battery. So sure, if this is seen as a disposable, go ahead. Personally, I wouldn't risk that insane setup on my worst enemy!

[@paulshanesmith]

I have this exact set up, 250SE, 120S and victron monitor so for anyone interested here's my experience. Its on an Iveco Daily with a 210amp alternator feeding a 300amp lithium leisure battery that has a continuous charge and discharge rating of 200amps. When the battery is at around 10% soc and I start the engine get slightly in excess of 140amps going in for a few seconds. This very quickly taills off and after around 5 minites of engine running the charging curve is below 100amps. After 10 minutes its down at around 80amps. It settles out at around 80amps with revs or around 70amps at idle. The curve then very very gradually tails off to around 30amps when the batteries BMS shuts down charging because its full. Its never the CTEK that shuts off the charging like I thought it would, always the BMS. On the whole I'm happy with the system but i think its misleading to market it as a 140amp system. The bulk of my charging is done at 70-80amps from an alternator that can charge up to 210a into a battery that will take 200a continuously.

[@nickanderson631]

Hey gents - great setup, just wanted to share my experience with high current charging. When I first put a bcdc1250 (50a) in my 105, I found it was also maxing out my alternators capacity at around 40-45a. Great for the lithium but it turns out it wasn't allowing the start battery to charge so it would keep going flat especially after driving at night. Hopefully you don't have the same issue but I'd get onto upgrading the alternator as soon as ya can. Cheers

[@AussieArvos]

Thanks for the info nick! not to mention its alot of load on that poor old alternator

[@TerryBrady-q5b]

One of the fun things about the SmartPass is that it'll trickle charge your starter from your lithium when you're parked up, and if that's not enough when you go to start the engine it'll just bridge the lithium in and let it help turn the engine over.

[@AussieArvos]

@@TerryBrady-q5b Yeah it's a pretty cool backup system!

[@-PORK-CHOP-]

Max charge on that battery is 100A, Kings Recommend only 25A charge rate to get the most life from it, the higher the charge on a Lithium the shorter the life of the battery.

[@michaellieberman2270]

Yes you will cook that battery very quickly with 100amp charge. Purchase a better quality battery with a higher max charge rate and the system will also have longevity. I have the exact same setup of CTEK in my van.

[@unrealshots]

Tidy install guys, but at 50A+ charge current you'll cook that battery pretty fast, as the manufacturer recommends max charge current of 25A.

[@Jess-xe8bq]

That is exactly why lithium’s burn. Can’t be extinguished easily either. Lucky it’s under the tray 👌

[@mattnorman9930]

Hey lads, I also recently purchased 2 x 100ah Slimline Kings Lithium. I'm really happy with them. I strapped them together and put them in series for a 24v trolling motor setup on the boat. I also had to make a tray as literally nobody sells a tray for the slim lines.

[@KevIsOffGrid]

All good, but you wont charge at over 100amps - max discharge is 100Amps of that battery, and max charge will be similar - that 55amps is a perfect 0.5C charge for that battery and still way fast enough, so no need to waste money on a bigger alternator.

[@billroach2393]

You beat me to saying that too.

[@biopsiesbeanieboos55]

So battery capacity and battery charge rate are not necessarily related ? Am I understanding that correctly ?

[@KevIsOffGrid]

@biopsiesbeanieboos55 no, they are linked. If you double that battery to 200ah it will take 200amps. Note that some BMSs are not equal charge/discharge and some may charge only at half the rate of discharge (BMS throttling not the cells unable to charge faster).

[@biopsiesbeanieboos55]

[@weriesblack1375]

Question is the main battery isolated from the system. I don't know anything about dc to dc chargers so can someone explain how the system is connected to get charge is it the altinator or onto the main bsttery with a disconnect at certain volts

[@sachindshan6503]

Got a question, why not mount the battery behind the passenger seat, away from water and dirt? Wouldn’t that be safer and use lesser wires?

[@ianweal3081]

Hi Liam, as soon as I heard you talk of 140Amp recharge alarm bells began ringing for me as Kings Lithium aren't rated for that recharge, other brands are (ex Itech) . Aren't you a tad concerned you're overdoing the charge rate as 25Amp is the recommended & 100Amp max, direct from Kings spec sheet below: Recommended Charge / Discharge 25A (0.25C) Max recharge current 100A Taking those figures into account, running at 50Amp is feasible. Just my thoughts. Just a tad concerned with water ingress with undertray mount. Should fully enclose by vented casing maybe. Regards, Wealie.

[@davesparkz]

Going over the recommended 25a charge rate will just reduce the life of the battery, thats all. Going over the max charge of 100a could damage the battery though.

[@franksteenhuisen7223]

Agree with this, a bit silly getting a lithium battery that’s main advantage is lifespan and then killing it prematurely with overly fast (or even too high) charge rate

[@MiniLuv-1984]

Nicely done. The quick charge is definitely worthwhile but check the max charging current on the Lithium - if you exceed that max charge current chances are the BMS in the battery will disconnect the battery...then no charging. If you put a small solar panel on the roof - 100 - 200W then the battery will be kept within safe limits when you park the vehicle for a few days. I imagine the two chargers, the shunt and other stuff will sip current 24/7 from the battery. Maybe you can fit a larger unit on the canopy when that comes?

[@lionridds]

Love the channel and watching your builds mare! 👌 Ctek charges are still my preferences after 14 years of using their charges. I fitted the same D250SE and Smartpass 120S in my camping rig to look after my batteries and it’s a game changer!

Again you lads have done it proud, keep up the videos,im sure a lot of us learn at least something from each video👍.

[@AussieArvos]

Thanks mate!!

[@RobertsAdventure]

Really good rundown of how to DIY a system! Only things I would be worried about is the effect of very high current charging on the lifespan of the battery - every battery prefers lower and slower (up to a point) and most commercial BMS limit amperage for that reason even if the battery can technically take more. BMS in the battery should try to protect it so I'll be interested if the BMS will fight you for overheating etc on a 100amp charge on a 40 degree day. Also the position of the battery and the bottom CTEK unit being low to the floor if you ever do take on water for whatever reason. Will be looking forward to how it does over time, if that battery location goes without a worry with normal use, vibration, puddles etc I think you have opened up a cool new option for a lot of single cab setups for those of us who wouldn't ever have to worry about a deep water crossing.

[@aulansalot]

Awesome, I love the video and how excited you get about the setup. I also love that you throw about $1,200 of CTEK and Victron chargers and shunts onto the $399 battery.

[@HammerRocks]

Another great DIY. You make it look so easy. I like that you guys are not brand snobs. I too have been using the Kings 120Ah (AGM) battery, 200W Solar blanket & 160W fixed solar panel for 5 yrs now and they're still going strong (touch wood). So when it's time to replace my AGM to a lithium, I have no issues using the Kings version. TIP: I'd recommend wrapping a bit of electrical tape at battery end of your split tubing to prevent it from moving and/or sliding. As over time this could potentially cause wear.

[@AussieArvos]

Thanks HammerRocks! nice setup! definitely will be worth going to lithium when the AGM dies, it'll make a massive difference! Cheers

Good call. You were proven right. He ended up destroying that battery, due to water ingress.

[@stco2426]

Excellent. Been looking at those C-TEK units. They are really popular for normal battery chargers and make generally great kit. I do like that Victron shunt, too. I wondered about putting a re-settable breaker instead of the fuse. The fuse could blow at an inconvenient time, especially if you’re around water etc and breakers are now very common and well used in these applications. It’s not uncommon for older vehicles, which weren’t designed for leisure electrics to underperform in these areas as you’ve found out, not just on wiring. Upgrading your alternator might be one thing but the new battery will have a max charge rate anyway. Not sure if you mentioned what that is? Your alternator choice might also be limited if it’s only driven by one belt. Bigger units tend to need two belts. Keep the great work coming!!

[@790125541]

Nice work guys, having done this myself could I be so rude as to make a few suggestions which you may have already done. I’m not familiar with Ctech but using victron DC TO DC myself, can you delay the charge to the secondary battery for say 1 min or so?. This will give the alternator a chance to recover the start battery voltage before charging the secondary battery. Kinder on the alternator. Second and you’ve already said it, a larger alternator. This is because when I measured the temperature of my alternator it was becoming uncomfortably hot, and six months later I ended up having to change the bushes, and slip rings ( basically a rebuild) of the alternator, from pulling so much power. However, great system you’ve got. I also mounted a computer fan to the DC TO DC charger as holding back all that current that wants to flow to the lithium ( which has comparatively no internal resistance) does generate a fair bit of heat, this caused the DC TO DC charger to dial back the charge rate which is good but not what you’re aiming for . Hope this helps someone.

[@SaltEarthandSun]

This is awesome guys. Nice work. Probably worth noting that the slimline lithium here looks to be rated for maximum 100A charge current. So probably don't want to be dumping 140A in there if you don't want to cook your battery.

[@bobwhatshisname2161]

Lipo batteries burn at over 2000deg C. Make sure you have that battery protected so you don't get a hole poked into the cells, and your system fused. I have just bough a kings battery, the same (great price) and wired it in parallel with another battery of the same specs to give me 200Ah discharge as I found 100Ah was great to run my fridge but not much else.

[@kradius2169]

Wow ... 11:08 ... Per CTEK, the SmartPass will try to start the truck with the aux battery if the starter battery is dead. Did you realize that? 15:20 ... The CTEKs should have (do have?) a provided accessory metal plate behind them because they're mounted on flammable carpet. The CTEKs are also supposed to have good ventilation. Do they? 0:30 ... I watched the video where the King battery is already dead & dissected. Are you familiar with AS/NZS3001.2:202? ... may not apply ... definitely good to know about, if you didn't already.

[@rawiridixon4430]

just a quick note why did CTEK reccomend a 300 amp fuse? a fuse is meant to be the weakest point in a system so that if there is a short and amps overcurrent, the fuse blows and not the less rated wiring and anyway 160amp (140 +20 amp) x 1.25 is a recommended =200amps.

Kings specs on the battery state 100A continuous charge/discharge rate, so he's currently well within that rating. Even with an upgraded alternator, he would only be nudging this rate short term allowing for covering the vehicle loads.

[@retrozmachine1189]

@@andrewr886 Have another read of the specs. 100A is the maximum rate. There's a price to pay for doing it and that price is lifespan. The recommended rate is 25A charge and discharge. The cell manufacturer's original data, if it can ever be obtained, will spell it all out in the charts. Of course going hard all the time may still meet the lifespan requirements for the given application but it won't be 2000 (or the nominal count if shallow cycling rather than full to flat and back). The closer down to 25A when charging the longer the life.
