I don't have the patience to try prying the perimeter. I get one for two returns on the battery boxes... I cut one below the seam and one just above it and pull the remainder out after the boxes are empty. I will get one good box that can be reassembled after cleaning off the silicone. The...

I received my order from Amy Zheng today. Overall, I will say it was a good experience. it took 6 business days to receive my 8-230ah cells, from when I transferred Pay Pal money to their account in China. There are fees from Docan for using Pay Pal and also from Pay Pal to send money overseas...

just did a second discharge test on the pouch cells. This time I wasn't as nice to it. 110 to 117 amp discharge using a 1200 watt heat gun. I set the current meter to 150 amp hrs to see where it would end up. At 40 amp hrs left I shut her down. I have no concerns putting this pack into service.

I reached out to Kuboka, who is selling the Chins battery on Amazon, and asked to return one of my two batteries. I obviously couldn't return the one I tore open, but I thought I would cut my loses and return the intact one. Their customer service was good and they promptly accepted the return...

the results are in...My testing equipment and procedures can not be considered expert, but, the current meter counted down from 100 amp hours to zero and the battery still had more to give. I kept the 50 amp battery load going for an additional 10 minutes. my stopwatch confirmed 50 amps for 2...

not yet. topping them off and will post results.

some additional pics. No visible part numbers except on the BMS. The thin foam on each side may be covering other info, but I'm not gonna mess with taking that off. Weight is 19 lbs without the ABS plastic case and 23 lbs with the case. Actually, it weighs the same as the Zooms battery with...

I'll see if I can get a part number of the pouch cells. I am disappointed they were not prismatic, mostly because of the box I intended to put them in, however, the build quality is not lacking whatsoever. Additionally, it caused me to go back and buy two more Zooms (for an extra 100 bux over...

It does match that battery exactly.

I purchased 2 Chins 100ah batteries from Amazon and tore them open hoping to find the prismatic cells that I saw in Will's teardown video. Much to my surprise, and not a great surprise, mine was loaded with pouch cells. The assembly was well put together, and super clean. Also, way less silicone...
