Video above (LC builds), 1st tri-box metered, right side supported by strap with 1 screw near 3/4" boards end grain, will split and drop right half from moderate to minimal turbulence?
If top strap screwed deeply into end grain, will support longer, but with same eventual failure.
:lol: :lol: :lol:
Very funny DA. One screw.
Try half a box of screws ; about 20 to 30 screws in each 10S - LTO box + wood glue and the bottom box that goes over the top bar is reinforced with fiberglass resin which is used to fix boats , cars , ect. If you dropped them out of a third or four story window they might split apart but not if the e bike tipped over.
If you look back to the start of this post ratchet straps and bungee cords were used and brackets with one or two skinny bolts to hold 3 - SLAs which weighed close to 40 pounds. They never fell out of the frame with two years of riding.
The 12S - LIFEPO4 box only weighs about 20 pounds and the 3S box on top about 3 pounds so < 25 pounds. The LTOs are > 40 and < 45 pounds. I need to try mounting them to a bike frame. I already ran the 15S LIFE all over town. That is not going anywhere. I will post an update on the heavier LTOs.
OK.
There are a few minor things that will need to be done and even if the e bike were to tip over the batteries wont go any where. Only a collision with a heavy motor vehicle will compromise the LTOs but would be the least of my worries in such a case.
Here is the video.

If you watch the video I will be using heavy duty L brackets in the back with a single bolt and wing nut for quickly mounting the LTOs. A ratchet strap and a chain will keep the boxes from moving even if the bike tips over.
The only thing I don't like is portable charging. I can not get away with bringing the e bike inside so if no AC outlet outside I will have to go thru a lot of trouble to charge. I will also have to haul them up and down stairs. Now you know why I want a solar charger in my van. I might get lucky and find AC outlets in the back of stores and buildings. I will probably get bitched at for stealing their electricity. I wont go to jail though unless I punch somebody in the face. :lol:
I am hoping I can get at least 15 miles round trip. 20 miles would be ideal. I might need a ramp to get it in and out of the van. I need to figure out how to charge out in the van. I think I will order a solar charging kit next month. I have the three SLAs and 33 Ah lawn mower batteries are $24. I own one. If I get two more I will have 99 Ah + 66 Ah = 165 Ah.
Not sure what comes with the kit. I do not even know what a solar controller does. I think it hooks to the solar panels , a inverter and the batteries for storage. ?????? I just want it simple. I don't ride a lot and can charge my LIFEPO4 batteries upstairs if the sun does not shine for a few days.
Its main purpose will be to charge the LTOs so I do not have to remove the packs from the bike frame as a lot of work. If a lot of sun then I can charge the LIFEPO4 as well and also a trickle charger for the van battery.
I might need some sort of ventilation for hot summer days though. If it is 90 degrees outside it could be 110 degrees inside the van with controllers , inverters and chargers.
Not sure how I can do that and keep it theft proof. An alarm would work but will at lease need a fan and the side windows open like an inch on each side.
If anyone has any ideas on a solar kit and a cheap way to ventilate the van for hot weather please post and let me know. The truth is for most trips it will be way easier to just run the 12S - LIFEPO4 as that weight about 20 pounds. About 23 pounds for 15S - LIFEPO4. It is another reason why I will order the prismatic cells. About 18 pounds for 25 Ah.
Unless I move to a first floor apartment or get a garage I probably wont hardly ever run the LTOs as too heavy to haul up stairs or inside some place to portable charging. That really sucks. That is why a solar kit for my van is important. It does not have to be fancy. I am looking at cheap barebones.
It don't have to power a house. Just run a 2 amp 54.6V Lion charger. The one I bought for the 13S - 1,200W - 20 Ah Lion pack in the van. I can also carry that on a rear rack or front basket for back up as I can charge it out in the van in an ammo box. Then I can go > 20 miles for sure. I just do not trust the factory Lion BMSs.
The one I have stored in my attic in an ammo box is 10S - Lion. It has a cell > 5V and a couple cells < 3V. I need to recycle it. I did not test the other 10S - 2P hoverboard pack. Both has its own BMS and were hooked in parallel with the 10S - 4P Laudation pack which all cells tested at 4.18 or 4.19V. That has a 15 amp BMS though so can not run it SOLO as even my Bafang controllers are 17 amps.
So basically I can run Lion again when I get a solar kit for my van. I can also run the 20 Ah - Lion pack but only with a Bluetooth BMS. The same with the 10S Laudation pack but need to build a 10S - 4P pack to run in parallel with it. I can also run the power modules in series with 4S - LiPo for 66V. I just need to order a solar kit. I am not even sure how to hook it up or what other components are needed. Will I need a separate inverter. I have a 120W DC to AC inverter which might run the 2 amp trickle charger.
54.6 * 2 = 109.2 watts.
Basically two more 33 Ah lawn mower batteries art $50 and that gives me 165 AH storage. So if my 120W inverter will work all I need is a really cheap basic e bay solar kit.

Will that work ???????
< $53 with free shipping. Probably $55 with the tax + about $50 for the lawn mower batteries which can go in series with the 3 - 22 Ah - SLAs for 165 Ah storage. Total cost < $110.
All I will run from it is a 2 Amp trickle charger and a 1 amp trickle charger for the van battery. If I want to when the LTOs are at full charge and the storage batteries are full or > 12.5V I can unhook the 2 amp and charge LIFEPO4 with a 1.5 Amp. So basically with that kit can I run 3 amps ???????
Please let me know. If it will I might order the kit this month. I need to know what is required for instillation though and how much extra $$$$$ that will be.
Thanks.
