Hello, yes I am looking for something that is ready to go I do not know much about assembling and testing battery packs
I am handy though.
I realize it may be a little intimidating at first blush but it really isn't hard to do. Will's Video's show the simplicity of assembling a battery pack. The tricky part is testing & balancing etc... but in reality, it is not that hard either and many make more of a big deal out of it than necessary really. The single biggest PITA with building your own packs, is getting everything to your door in a timely fashion so your not sitting for weeks waiting on stuff... which by the way is very trying on the brain - that whole impatience thing, with a dash of worry and a pinch of fear that something will go terribly wrong somewhere...
When I decided to go from Lead to LFP, I bought a Pre-assembled Value Pack. 24V/400AH for $3000 USD but I got suckered and got used 175A cells (for 350AH total capacity) , craptastic BMS and a lovely stainless steel casing. Boy was I (*^%#(()*+)(@*&+_ !!!

Then I decided to build my own After Recovering that ShunBin mess (version 1 rebuild). I ended up buying 280AH from XUBA (and started that massive thread) and went forward and built 2x 24V/280AH packs. 16 Cells cost me $2433.00 USD then (NOW $1706.00 USD from Luyuan) and that is delivered DPP (Duties/Taxes Paid) to North America.

(NB, they have a few brands / capacities &
Xuba 4S2P 12V 200AH Lifepo4 Lithium Battery Pack $466 + S&H)

It may be prudent to sit down with a calculator and your bank book and see what makes you happier while remaining comfortable. Sure you will not get perfectly matched, batched & binned cells (that's a costly process) but even so, these are a terriffic deal and you will get more capacity and the knowledge of how & what to do.
Just to give you a comparitive set of numbers. (NOTE: Be cautious when advertisers state kWh values as it depends on the voltage for the calculations and "marketers" play the numbers game.)
12V/280AH = 3.36 kWh @ 12.0V or 4.088 kWh @ 14.6V 12V Pack - 4 LFP Cells
24V/280AH = 6.72 kWh @ 24.0V or 8.176 kWh @ 29.2V 24V Pack - 8 LFP Cells.
Hope it helps, Good Luck
