Lishen Battery/Solar build

Acho_303 · Jan 29, 2021

Hello everyone,

I am beginning to mature a new battery/charging system for my van and will document the process with a hope for feedback from members and to help any new members, such as myself with their endeavors.

Batteries: 8 Lishen 272ah cells
BMS: 2 JBD 120amp
Solar: 400 watts
MTTP: Victron SmartSolar MPPT 100/50
Inverter: Victron Energy Multiplus 3000va 12 volt pure sine wave inverter 120amp
DC to DC: Victron Energy Orion-Tr Smart 12/12 volt 30 amp 360 - Watt DC - DC Charger, Isolated Bluetooth

Random:
Victron Energy Color Control GX, Panel and System Monitoring
Victron BMV-712 Battery Monitor with Battery Temperature Sensor and 500A smart shunt
Victron Energy Lynx Distributor

My cells arrived yesterday and are currently warming up after their travels. They arrived with either 3.24 or 3.25 voltage, hopefully thats okay.

Tonight I plan on starting to get supplies to compress the batteries to top balance to 3.6, my charger does not have the ability to do 3.65 so 3.6 it is

The plan is to use half inch pink board and batlic birch boards with all thread to compress. The order will be baltic birch then pink foam board cell foam pink board baltic birch with all thread sandwiching everything tightly

I am very excited about this build and look forward to anyones comments. I feel like I am flexing, lol.. After 4 years in my van with 250ah of AGM I feel like I am certainly upping my game

Quite interesting

Just received my 8 Lishen 272Ah a few days ago. Will put together two 4-cell batteries with each a JBD 120A BMS. Will add later the Multiplus 3000. Consider the Orion DC-DC if necessary. No BMV712; most f that info should be available from the BMS's on my phone.
I'm adding this to my 600W solar system of my van conversion.

Nice, I went with the Orion over renogy because I read some bad renogy reviews, and figured if needed I can add another Orion. I wish I had more room for solar but early in my build I added two maxxair fans front and rear, so my roof space is limited.

Your battery setup will be the same as mine! What was the voltage of your cells when they arrived? It took 40days to arrive in Colorado and mine are at 3.24 and 3.25, so about 30% soc +-

I ordered them on Nov 26, 2020 and received them on Jan 26, 2021; exactly two months to Florida via LA.
3.272 - 3.275 - 3.275 - 3.275 - 3.276 - 3.276 - 3.276 - 3.276. Have most of the cables, fuses, lugs, BMS's, etc. waiting for assembly. As the + and - connection points of the cells are the weak spot, I waited to double check their size and just ordered the remaining set screws, nuts and washers, that I needed. I'll have those this Monday and then the work starts.
I have three 135W high quality flexible panels on the roof. Each of them fit exactly between the gutters of my Ford Transit, with an inch to spare. That gives optimum coverage use. Could probably fit another on it at the front of the roof, but that one would be slightly visible. You can hardly notice the other ones. I have only one MaxxAir on my 2016 Ford Transit 250, 144", medium high roof. For improved ventilation, I have a floor vent at the opposite end of the van (front), that pulls cooler air from under the van. I will be posting the entire installation in great detail on my website and YouTube channel. I'll keep following your post and we can exchange data or info.

So where are your cells from? BASEN?

I have the same from XUBA.

I made the case today, to be honest I am not completely satisfied with the build... but as most things they never come out perfect.

Materials

Let's get started

Cut the handles, at this point I am using the cutting boards as a template

Next I rounded the corners

Then edge banded the 1/2 balyic birch

Acho_303 · Jan 30, 2021

Cleaned up the banding

Next drilled some holes and noted to myself I really need a drill press

Next cleaned up the handles a little

Oiled the wood

Let it dry

Started working on the all thread with tubing around it

Place washer, lock washer and vibrate proof nut in groupings

Acho_303 · Jan 30, 2021

Then started to work on the cutting boards

Test fit

And a real test fit to measure where I need to cut the all thread

Next I used a grinder then sanded the all thread so the nuts would go on

Assembly

Acho_303 · Jan 30, 2021

Sorry about the poor pictures, since I live in my van full time my garage is my other project, a 40ft flat nose school bus I raised the roof 20 inches on

Basen, it was my first order and I went to them based on another thread in the forum...

I may be an easy judge, but I think that looks like great work @Acho_303 !! You wanna build mine?

Hey thanks, thats is very kind of you

Acho_303 · Jan 30, 2021

My victron Lynx doesn't show until next week, so once I have that I will start configuring where all the components go and start sodering lugs to cables

Acho_303 · Jan 31, 2021

Its a really sunny day today (my agms are a 13.2) so I started charging a cell to 3.3 to watch how the charger works.. In theory since the cell is at 3.34, the voltage should drop to zero when it hits 3.3, and my voltage meter should read 3.3.. Lets see what happens

Acho_303 · Jan 31, 2021

Well, I guess I am too excited to start having power so

2021-01-3111.02.558628655262428197832.jpg

I am laying right next to the batteries and checking the voltage every few minutes and will drop the charger way down when 3.5 hits... I just need to maximize the sunny day

Acho_303 · Jan 31, 2021

Started charging at 11am at 10amps, its now 3:30 and the cell I have been charging went from 3.24 to 3.31, lol this is going to take forever
