352 Samsung 30q cells 3.8kWh module
These modules are 71.5 lbs so they have to ship freight or local pickup. We can't ship this fedex or ups ground due to lithium battery shipping restrictions. If it was under 70 lbs we would be able to but this module is slightly over. Flat rate freight shipping is $350. If you buy 1 or 20 of these the cost will stay at $350 so the more you buy the cheaper the shipping becomes. It would be worth the freight cost if you are buying 4 or more.
These modules are awesome but unfortunately a decent percentage of cells have been discharged. Seems like the BMS was faulty. We did break down one of these and the cells that were 0v did take a charge and tested just fine. These modules have so many components including relays, circuit breakers, metal enclosure, wires, nickel, connectors, etc. The cells are actually spot welded into 4p modules with a post in between which is super cool and something we have been wanting to do here as well with that type of design. In the end, for $299.99, you can't go wrong here. Easily $150 worth of components on top of the 352 cells. This was set up in 88s4p and the dates are relatively new so likely these were assembled and had a bms defect so you can expect the cells to test very well and the ones that were discharged down to 0v have not been sitting that low for long so they will revive. The Samsung 30q cells are one of the best 18650 cells on the market.
