200A discharge 3.7V 8AH flat pouch lithium ion cells [Spim08hp]

At the size and weight you could have it be in a small travel board or also a light MTB jumper both with a ton of torque. Both where sub esk8 mile range may be ok. Idk about the travel board tho 12S2P 2170 a good idea but maybe more $

Just for consideration of where it may be properly fitting as a 12S1P board.

Cost is always the other thing to weigh with these things. 30g

My first board I ever built was a 10s1p and it gets about 5-7 miles on a charge. The second board was built using the remaining 12 cells since of the 24 i bought 2 were bad. It served me quite well through the winter months and summer of 2020/2021.

Still working on my “primary” pack 12s12p “tesla cells”.

I think I just had a fun idea I will Paint a White and red plus sign on the side so it is not an ammo box it is actually my First aid kit. That is full of batteries.

I think I will make 4 screws come out of the bottom of the box where the feet stick out then use nuts and safety pins in case those come loose. Then you just take a skate tool and remove the box with 2 nuts with the xt60 built in or maybe on a cord.

Small ammo can fits 10 cells exactly with no room for any foam at all, so good thermal conductivity I guess?

On either end you can shove a VESC6 also a 10S3A charger(case is too tall) and a Xenith on top fits nicely.

Ok I haven’t made the 10S to fit that metal ammo box above funny enough the case I’m about to show also fits 10S exactly so that is next for sure.


Thing is the cells fit so tightly in the long dimension there wasn’t a single millimeter spare for how these foil crimps normally poke out on the top and bottom. So I had to trim the tabs so that dimension would stay at 210mm or whatever.


2 hours later, cells I actually tested and matched for the first time. Idk the time to make the harness but 1-2 hours as well.

Just barely squeezes in without bending the ends.

Harbor Freight Apache 1800 fits 10 spim08hp 200A pouch cells, idk if room for a BMS even.

I wanted to add that while cutting the tabs and putting that last pack together it occurred to me that using screws and busbars would fit just fine in this cases close dimension… guess I should try that for one.

Dude, I happen to be doing the EXACT same thing…

10s1p using the foil crimps in the small HF Apache case. Debating about stuffing a Daly BMS in there too, or to just add the harness to enable balancing “occasionally”.

When I get off my lazy ass and work on it I’ll snap photos too.

Swag ma man cool to hear! Excited to see anything else interesting you find putting yours together.

Here you can maybe see how I cut a few mm off carefully aligning before crimps and tape. Also I finally tried heat shrinking these packs with 220mm clear PVC, that size just barely fits 12 cells but also shrunk down enough for 6 cells. Nice that I randomly picked that.

For anyone in EU/SWE, I have a bunch of these for sale.

how useful are these for the weight ratio?

For example a 10s 4p 30q vs equalivant of these?

you do the math

How much per :)?

All of them are reserved for now, will update if deal falls thru

@Fosterqc , just following up about the 10s spim08 pouch cells in HF Apache 1800 case. It came together for me as you described… tight fit particularly in the long dimension. Daly BMS just fits on top. Here are some photos. It’s been in service for ~4 months.

Awesome I noticed they get quite warm in a foam case, they die before melting thankfully.
