Anyone built a 24v 100 ah bank using 32650?

[adriansantos]

Planning to replace my damaged Gel Deep cycle battery. Am planning to use the 32650 LiFePo4 3.2v 5ah battery. Seen videos but the max i noticed were less than 40ah built, just wondering if there is a limit for this type of battery. Have checked the 8s BMS for this battery but am not sure, what is the maximum number of batteries i use in parrallel.

If I'm running the numbers right, you need 32 cells for a 12V battery for 40Ah. 64 for 24V. That's going to be hard to manage physically

Tesla puts an ungodly number of 18650 cells in parallel in each cell group (74). Since they're explody chemistry, they fuse each and every one. Not necessary with LFP.

I think the limit is what you can manage.

This stuff makes the fusing trivial to do.



Sadly, looks like Battery Hookup is out of stock.

NICKEL FUSE 2P-6P WIDE CONTINUOUS ROLL BY THE FOOT! 18650 CELL LEVEL FUSING

Each foot equals 15 cell connections long by 2, 3, 4, 5, or 6 wide. For example 2p wide would be 30 cell connections per foot (2 wide x 15 long) and 6p would be 90 cell connections per foot (6 wide x 15 long) Introducing custom cell level fused nickel design that can be spot welded with ease...
