I’m putting together an excel spreadsheet with all the parts I’m going to need and I’m pretty intimidated by having to assemble my own batteries. I’ve found this same battery shown below for approximately $300 shipped (14s5P). My plan would be to get 2 of these (I’m planning to build a tow boogie). Any thoughts on the quality of these batteries and if they’re a good battery to get?

Specs (current) looks OK
Battery looks heavy and unfortunate shape for eFoil though (flat batteries are better fitted in a board), maybe not that important for a boogie if you don’t have to carry it far 😃

If that’s not a good setup do you have any suggestions for premade packs, either 14s10p, or 12s12p?

I don’t have any recommendations for the US market, sorry.

You can try the guys at [https://diy500amp.com/](https://diy500amp.com/).
They do custom packs. Just give them a voltage and the AH capacity you want. Don’t need to specify a p count unless you know specifically what cells you want (they sell a bunch on their website)
That razor pack looks okay as a battery. I would wonder if it would sit too high on a tow boogie and add some risk of the whole thing rolling over

The owner, Nelvick, is an awesome guy. Getting a custom battery from him wont be cheap, but it will be really good.

A couple other places to check out. I found a used one on MBoards (haven’t used it yet but seems like good quality. Can’t wait for the lake to thaw out). It looks like they do custom options too. I found Z Battery in my search but never contacted them.

@DIY500AMP.COM nice to see you on Foil.Zone! A very clean pack build. Interesting that you don’t use any spacer grid for the cells. I guess that’s a laser cut fiber board on the top and bottom? Is that glued down or taped in place? What type of spacer have put between the p-groups?

Roger.
Normally I do not build without cell holders but this was a very specific request by the client since he explain otherwise will not fit in the factory box. I use fish tape to separate the P-Groups. Everything was cut with the laser yes.
