BH has a sale that ends at midnight tonight (7/21). https://batteryhookup.com/products/8x-new-sab-3-2v-55ah-176wh-60280-cells $199 for packs of 8 cells.
I just ordered 5 of these 8x packs for $1040 delivered (using 'DIY' coupon). I'm planning on 8S5P to give me about 7Kwh at 24v.
That seems like a good deal. I pulled the trigger on this due to the pressure of the sale, then immediately wondered if I made a mistake. It looks like EVE cells from Amy at Shenzhen Luyuan are quite popular in the forum, but shipping is a mess right now.
I know the mounting/connection process for these radial cells is very different. The BH site says no need for compression. Just bolt up the bars and you are OK. Are there any issues I should consider with radial cells?
I'm sweating this because I bought 4 of the "BYD" modules from BH when they were a thing. I've fought with them on and off ever since. Mine just aren't reliable. I've top balanced them multiple times but 1 cell or another always seem to run away from the rest of pack after some use. I should have complained to BH when Will pressed them on the issue but I didn't so now here I am. That's a whole other story I can detail but my point here is I want reliable batteries.
So should I cancel this 60280 order and before it's too late (TODAY) and order from Amy, or will I be happy with these 60280 cells?
Also, I plan to use the Overkill BMS but they appear to be on back order. I'm going to reach out to them for an ETA of new stock. Does anyone have thoughts on that? Is there another option I should consider?
I'm going to use an all in one 2Kw Inverter/Charger and add some solar panels later. For now I'll charge with a Honda generator on my boat.
Low temp cut off is an issue as the boat is unmonitored during the winter. I've thought about just disconnecting the bank from charging over winter but I'm worried about the impact of self discharge.
Thank you all in advance for any opinions or suggestions you care to share.
