There are very little differences in the quality of build or frankly any attribute of the SOK vs our packs, this gear was out there, we vetted it and brought it to market to better serve our clients.
The one difference we see in the SOK is the bolting of cells, we have been down this road but as we scaled we had the factories adjust to welded connections because the reliability of resistance is superior to a bolted connection over the lifecycle in many environments that do not have perfect climate regulation, Welded connections also allow for use in RV and transport because vibrations were too risky for bolted cells.
the last bolted EG4s shipped in early 2021, we have been lucky overall so far but determined the welded assembly change was going to make sense over time as we service the warranty.
-With the LifePower4 brand we allow you to get a value price on the same gear taking the 5 year warranty approach.
-If the longer warranty matters to you the EG4LL models have an LCD on each as a perk and we think that given the fact that all the warranty profit goes to an American based company you can be more assured of the promise made at time of sale will be kept.
-Our warranty is a full replacement for either model during the period.
SOK did make the right move as a Chinese company to partner with an American company, Current Connected is doing a good job for them. I think our business model puts more of the value in the hands of Americans and make more design and support jobs here vs padding excess Chinese pockets. I would think that a current connected brand going direct may accomplish this but that is their business model to manage.
I asked the sales team in a meeting last week, we do not honestly hear about the SOK battery that often, the market is so big for a value priced solid lithium pack. What I can tell you guys is that if you choose us we will stand behind your packs and make more jobs here in the USA in doing so.
