Default Custom LiFePoO4 question

I have a lifted 2017 CCP running 22" tires, stock controller and stock motor.

After going back and forth a few times between 280Ah and 150Ah I finally decided to build my pack out of 3.2v 150Ah batteries, mainly due to space.

The plan is to build the batteries in series for a 48V 150Ah battery.

Now the last part - how do I charge the thing. I have the stock ERIC charger and a quick visit to the mfg website says not to use them on Lithium batteries. For those who have built batteries, which chargers are you using?

I ordered a custom Schauer for mine. Tried to make a Lester Summit II work but no love!

You need a charger designed for lithium batteries, which is simply a current limited constant voltage power supply of appropriate voltage and current.

For 16s LiFePo4, the maximum voltage should be 58.4v, but it can be reduced to 57.6v with very little loss in capacity but an increased service life. The maximum charge current can be anything up to 75A although trying to charge at that high of a current has other challenges such as a suitable AC outlet (58.4v x 75a = 4380w) and heat generated in cables and connectors.

Cheers
Pat.

Have a link to the 150ah batteries? I’m starting to look around at doing the conversion as well.

Just make sure you balance the batteries first and use a bms and fuses. I apologize if preaching to the choir

Can you give me an idea of where you’d put the fuses and the size of them? Starting to dig around on a project like this.

Your controller should have a recommended fusing and wire size. I would start there. I think my alltrax came with a 400a fuse.

With batteries, I always put the fuse on the B+ terminal or on a bus within 7” of said terminal. Whether 250a or 400a fuse, that is a lot of current, be careful.

My 500 amp Alltrax actually came with a 300 amp fuse. I have two of them in two different Yamaha carts. I installed the fuse at the negative battery terminal for convenience but you can put it on the positive if you like. I have run the monitor program with my Alltrax and even under full acceleration it never gets over 300 amps battery current. It would have to be quite a bit over 300 amps for several seconds to blow the fuse.

I've bought a Converter/Charger from AIMs for my 48v build ($239)and just picked up an adjustable 36v from Battery Evo that I like for the price ($169.00) because I can adjust the voltage. The AIMs seems to be built better, but in the end, they both work as designed.

I got the batteries off a reputable guy in the diysolarforum - he doesn't have a website up yet but I can try and get his off-forum contact info if you like.

I'm aware of the need to balance but have questions about the process. All the folks on youtube seem to have a power supply they're doing them with. If I'm going to build one battery, buying one would be kind of a waste. Can you just top them off using the BMS and a charger?
