Thanks. Just bought one. It charged my brand new SOK 100ah battery in about 3 hours

[@sprinterdiscovery]

Yet another great video my friend! I love how you do the cinematic shots of the devices. The Victron IP65 15A is an excellent charger - very versatile, and its nice to see the status over BlueTooth with the VictronConnect app. It's too bad we can't use this to act as a power supply to the Yeti 1000 - the Output Voltage only goes to 14.70V maximum, whereas the Yeti minimum is 15V. I use this charger in my Sprinter van connected to my Yeti 1000 110V outlet. My Yeti 1000 will charge my Sprinter battery while I'm using my Espar D2 heater so that I don't fully drain my starter battery when we are out camping. Then when we drive, we use the Victron Orion DC-DC charger 12/24-15A to charge the Yeti 1000 back up again. The IP65 and the Victron Orion DC-DC chargers are game changers with the GZ Yeti's!

I've had this charger for a few months now. I initially bought it to charge my Goal Zero (AGM) Tank without connecting the tank to my Yeti 3000 & Link. I found the charging information provded by the phone app to be much more informative than the 4 bars on the link. One thing I found impressive is the charger's ability to bring back a SEVERELY depleted battery, like a seriously dead battery. From the manual "Recovery function The blue smart charger range will attempt to recharge a severely discharged battery (even down to 0V) with low current and then resume normal charging once the battery voltage has risen sufficiently - many other chargers will not recognise a battery in this state."

Hi Todd, Just something to be aware of. Charging profiles for Li-Ion and LiFePO4 are slightly different. Most likely you will need to create a custom profile for the charger. There are some posts about this in the Victron Community Forum. For the reasons of safety and battery life longevity, it would be best to change some settings.

Nice Review Todd! I was using a NOCO Genius 10 to charge a 100 ah Battleborn Battery. Because I was testing out a new shunt (AiLi) I did a discharge capacity test on the Battleborn and once it was fully depleted, set the shunt to zero and started to charge with the “Genius”. I observed that it never went into Bulk or absorption modes and very slowly charged the battery at a curious 1.43 amps. The charger turned off several times and never could charge more than 78 ah. I tested the NOCO 10 with a second Battleborn battery that was 90% SOC and saw the same 1.43 amps without going into absorption mode, voltage…rarely went above 13.4. So, I will return it for evaluation, per NOCO’s 3 year warranty. I am thinking of getting the Victron you enthusiastically endorse! Did you observe the charge cycle to see what the amp charge rate looked like? Thanks Again.

[@todd.parker]

Yeah, my NOCO never worked well with my LFP battery and was so slow. I know for a fact this Victron shifts to bulk mode for most of the cycle and it has handy lights on the unit and the app to monitor it’s charging. Mind is still working great - it’s built like a (waterproof) tank

[@jacksherman7445]

@@todd.parker Update: I did wait out the charge cycle for much longer and with my AiLi shunt I did see that it got to 14.4V at the end of the change. The Genius 10 charging profiles is likely a very battery-healthy charge cycle--if you have the time!

I have a ReBel 100AH Lifepo4 battery. I see lots of people say use a 10 plus amp charger for them. But some say use a lower amp charger to extend the battery longevity. I have a 4 amp charger for now till I get a bigger amp charger. My question is that, should I go low and slow ( 12v 7amp ) or high and fast ( 12v 15 amp), or in between ( 12v 10amp ).

[@todd.parker]

Depends on how much of a rush you’re in but charging fast dies degrade the cells. I think less than 0.2C (20% of capacity) for charging or discharging is very easy on a battery so the 10-15A amp is totally safe. The eco flow units charge at 0.6C or faster.

HI, just watched your video twice just to make sure I got it... and ordered the Victron charger. Question though...SETTING up the question: I have a Goal Zero Yeti 1000 that this will be charging. However, I use it in my camper van and doubt that where ever I go that there will be an outlet for me to plug into... BUT the Yeti 1000 does have 110-120 AC... AND I do have a Yeti Link that will draw power when my van is running (plus 200W Boulder solar panels). QUESTION: Can I plug in the Victron into the Yeti AC, and then have the external LiFePo connected via the 12v car plug into the input of the Yeti using the Goal Zero 12v adapter? (Sorry that was sooo long)

[@todd.parker]

Hi. Yes, you can connect the Victron to the AC on the Yeti and trickle charge the Yeti from the battery when needed via the car charger. There will some losses because you’re convert to AC then back to DC but seems you have plenty of power. I might suggest that you don’t leave these always connected because it seems like it would be a circular thing with the yeti charging the battery and the yeti pulling power from the battery to replace that energy so it could self discharge faster than ideal. I’d plug in the external battery if the yeti is running low to keep things going a bit longer

[@todd.parker]

Yes, you can connect this to the AC output of the 1500X to charge an external battery, that's what I use it for. I haven't measured the actual power draw but I'd guess it pulls around 200w-250w when in bulk charge mode.

Can you still read the status of charge on your battery when it’s not plugged in? Ie. batteries under load and acts as a shunt to monitor battery level without 110v?

Unfortunately no. It will just run out eventually but since it’s a fixed charge rate of 100w, it’s easy to calculate the time it will run for. Seeing the overall state of charge is the big advantage of a true expansion battery

[@SeaToSummit1969]

Is it safe to attach this to a LiFeP04 battery that's hooked up with a Victron MPPT and solar setup? Would I need to disconnect the solar setup and MPPT before attaching the IP65 smart charger or can they all be hooked up at the same time and regulate each other?

It seems they should work together since they mostly just check the current battery coverage and adjust the power coming in. The battery could be filling up fast because it’s small or because your pumping electrons in from the wall charger

Another excellent video. I have a question about the Victron Energy M8 Eyelet Indicator for Blue Smart IP65 (30 amp ATO Fuse). The description on Amazon states: "Suitable for 12-Volt lead acid batteries only (flooded, GEL, AGM). Not suitable for Lithium". Did this item work for you while recharging the Lithium battery ? Thanks. I emailed Victron and asked them for an explanation. Their replay to me for why the M8 Eyelet is not compatible with Lithium Batteries was: "As a lithium battery doesn’t have a voltage which indicates its soc (State of Charge?) as a lead acid does." What?

[@todd.parker]

Ah, I see. So that’s an fancier eyelet connector with a SOC indicator. The one that ships with the unit is a simpler one with a fuse only. I think the issue is that indicator is calibrated for lead acid batteries and lithium ones have a different discharge curve that’s much flatter - it stays at a steady voltage for a long time then drops off while a lead acid battery starts drooping all the way through so they can use that to roughly indicate the % full.

It is true Lithium batteries, such as in this video, come with a BMS device to protect the battery from either over charging or over discharging.

[@katecapil4574]

I felt very concerned seeing it can charge to 14,7v. I would not trust it with my lfp.

[@toddtenhet1565]

I wonder if my Honda 2000 genny will run it at full charge amps.

[@todd.parker]

For sure, this only uses about 200w

[@MarioBruneau]

I use this battery for my Minn Kota 30lb electric motor and wondering how you know how much power the battery has left? Since it is an intelligent battery, I was expecting a visual feedback directly on the battery but I find out I was dreaming. Anyway, how do you monitor your battery power on the go?

[@todd.parker]

Yeah, I don’t have a way to monitor the state of charge. The Victron smart shunt would be the way to go if you want a detailed SOC

[@4444mongo]

Hi can I use a rc life charger 20amps 300w capability

[@todd.parker]

I’m not sure, I’d be careful unless it has a changing profile for this battery chemistry

[@4444mongo]

@@todd.parker just testing it out and negative terminal is getting hot on the battery itself is this normal how hot is too hot?

[@4444mongo]

@@todd.parker battery got charged but another problem is my trolling motor doesn't like 14v It won't even budge, water snake works fine with normal lead acid battery. I m wondering if I have to get a step down conversion.

[@todd.parker]

@@4444mongo huh, interesting. I wouldn’t think 1v higher would be a problem. You could get a step down but you’d need a pretty big one to run a trolling motor, those pull a lot of amps

[@todd.parker]

@@4444mongo they might get a C bit warm but hot is a bad sign. If your charger doesn’t have a specific lithium battery profile, I wouldn’t use it

[@Simcore999]

I don t understand, my 12v 10ah takes 8 hours at 1 amp so shouldn t yours take not more than 10x more?

[@todd.parker]

Are you talking about my Noco 1a charger? It took about 100 hours to charge the 100ah battery.

[@Simcore999]

@@todd.parker Your 12v 100ah battery( ies), regardless

[@todd.parker]

Sorry, I’m confused. You’re saying your 10ah battery takes 8 hours and my 100ah takes about 10x longer. Seems the math adds up?

[@Simcore999]

@@todd.parker Mine is lead-Acid, It actually takes six hours but they recommend 8 for better conditioning

[@todd.parker]

Ah, gotcha. Since you really can’t discharge those below 50%, you’re probably only charging yours about 5ah each time vs. a full 100% recharge with lithium. That’s why I didn’t realize just how slow this chargers was when I was charging my AGM battery. It had half as much work to do

[@pascalbruyere7108]

Put the charger rings on top.

[@fobguy714]

noco genus G26000 ?

[@todd.parker]

That one should be pretty good since it’s 26A vs. my 0.5A version :). I like NOCO but they’ve had some quality issues recently

[@drpc98014]

you paid how much ?!? my 100 ah battery was much less. also renology and battleborn are my least favorite

[@todd.parker]

This is a pretty old video. Prices have changed a lot since I made this

[@drpc98014]

@@todd.parker Yeah sorry about that. I didn't see the best by 3 year ago date. anyway I'm looking for a small fully automatic lfp chargers that I could use to replace UPS sla chargers with, 20 amp and 5 amp sizes. any favorites? fyi I just paid 150 for a 100 amp hr Any favorite

[@nikolndasler1942]

Lifepo4 not connect for this charger , Y alone see ?

[@todd.parker]

You can use the lithium setting

[@skepticalmechanic]

You should have bought the 22 model… it’s 30 amps with three outputs.. $225.00

[@todd.parker]

Looks like a good unit

[@big6pun07]

Wow i just payed 250 for my battery it was a li time battery

[@todd.parker]

Yeah, batteries have dropped a lot in price since I made this

[@robertdillon9989]

Ya, but I pay 339.00 all day fir similar batteries, ya gotta do your homework !

[@todd.parker]

It also helps to buy a battery over a year later. Prices have come down dramatically. At the time, that was the least expensive LFP battery.

[@Mark-wv6sg]

To small at least 30 amps

Bigger is always better

[@paulnotdownunder3172]

App wont load these days. Do a review WITHOUT tje bloody app please!!

[@todd.parker]

The app doesn't do much honestly. The main thing you need to set (battery chemistry) is done via a button on the unit so it's fine w/o the app unless you want to do advanced things.

[@glensalmon3695]

I have 2 x renogy 170ah lithium batteries and the 10 amp noco is a much better charger. don't plug a charger without trying others first. waste of tube time.

[@todd.parker]

So have you tested both and measured a significant difference in charge time or quality? Otherwise, I’m not sure why you’re so dismissive. Edit: I see you commented twice. Guess you’ve tried both.

[@jacksherman7445]

I have a NOCO Genius 10 and find it takes days to charge a 100ah Battleborn. Healthy for the battery, but very slow.

[@todd.parker]

Yeah, your battery is really taking it easy

[@glensalmon3695]

peice of crap charger. I owned one. cheapest item victron sell says it all. stick with what you first search showed, the noco genius 10. I now have 2 after owning the crap victron.

[@jacksherman7445]

It takes me nearly 3-4 days to charge a Battleborn 100ah 12v battery from zero to 100% with my NOCO Genius 10.
