GoKWh 100Ah LiFePO4 Battery Teardown

Look inside the GoKWh 100Ah LiFePO4 battery with Blue Tooth & an LCD display showing battery voltage, state of charge or capacity remaining, charging or discharging current, and temperature. I go over its main features, test the capacity, voltage versus depth of discharge, accuracy of the internal meters and the temperature cut-off. I also do a tear down to look at the construction and quality of internal components.

Looks great, a lot less work than building your own pack from scratch. I made a 12v regulated voltage supply with a cigarette plug adapter for my scope using a regulator from Digikey and parts from O’Reilley, and mounted into a converter box.

Great info, thank you it sounds like a deal.

[@jamesward2276]

Good eval. Nice to see the guts. I am curious how accurate the BT system tracks SOC. Have you done an extended eval?

[@astronomytipsreviewswithcu740]

In the video I do mention that the LCD display accurately tracks with my external measurements of voltage, current and SOC during a full discharge cycle. Since the BT will use the same data from the BMS that the LCD does, the answer is yes. If you decide to order one of these batteries use the link below my video and the coupon code which could get you $20 off the price if it is still valid.

Thanks!!

[@PaoloStivanin]

thanks for the review! How would you proceed to connect all equipment to the battery?

[@ronm6585]

Thanks for the review. 👍🏻

[@hashiramasenju254]

how long is the waiting period before your received the battery from gokwh?

[@astronomytipsreviewswithcu740]

Since they sent this to me to test I don't think my timeline would be a good indicator for a regular purchaser. But it took a week since their wherehouse is in southern CA and I am in northern CA.

It's too bad you delete helpfull comments and a better battery and a much lower value! Your not helping Astronomers.

[@astronomytipsreviewswithcu740]

I have not deleted any comments. Tell us about the battery you say is better.

@@astronomytipsreviewswithcu740Hi Curtis, I also have been looking for a good 12v 100AH lithium and came across on Amazon 1 that was so different that I ordered 1 and during my discharge at 10 amps got 96 amps at a cut off at 12 volts. I just wanted to let others know as what I liked about this battery is a few screws and you have access to the cells and BMS, but what made it really good is a Low temp cut off and I am able to add a whole bunch of items, like 5.5x2.1 connectors, a digital readout, battery heater as the cells are smaller then the outside case. When I reached out to the company as all of these are made in China and when I asked them what is the BMS and cells and within a few hours I got the spec sheet and this company makes the cells! Almost all of these battery are just rebranded. www.amazon.com/dp/B0CN8R1BGK company called "Oasesenergy" for $189 + $5 s/h from California for under $200 I was shocked. When I posted it just helping others that may not have $300 this was an option. When I looked this morning it was not there so sorry I was thinking you removed it? This is a very small hobby and trying to help the low budget Astronomer as I am one...

[@zygmuntziokowski7877]

It looks nice, but the battery is made in China. I prefer USA product.

[@astronomytipsreviewswithcu740]

I think 90% of the batteries are made in China these days. Not only that, most of the components inside the batteries made in the USA are actually made in Asia. There is little to no cell manufacturing in the US at this point, except for auto mobiles, although that will eventually change. But, I understand some prefer a battery assembled in the US.

[@whatmattersmost6725]

Sorry just about everything is made in China as to Lithium cells! I agree with you but we let this happen... So sad.

[@astronomytipsreviewswithcu740]

Not to worry, there are efforts underway to build in the US which I am happy to see.@@whatmattersmost6725

[@whatmattersmost6725]

@@astronomytipsreviewswithcu740 that will only increase the selling price.

[@aagifford]

Well, nearly everything is made or sourced from China. Regulations and price drove nearly all battery manufacturing out of the USA. There is some insourcing going on, but good luck finding a pack.
