Nice touches in battery build quality tbf, even though they're relatively cheap compared to your previous teardown, but thats built to iso i suppose, the UK belt n braces. Keep them coming brother 🤞👌
C rating is simply a rate at which a battery will fully charge or discharge under normal use. So a 100 amp hour battery would take 5 hours to charge at 0.2C or 20 amps (100/20 = 5) The same battery would be fully charged in 1 hour at 100 amps (1C) So our 50Ah battery uses the same formula 50/20=2.5. If we used 10 amps (0.1C) it would take 5 hours to charge a 50Ah battery and 10 hours to recharge a 100Ah battery. Higher the C rate, the faster a battery will charge or discharge but every battery has a specific C rating as set by the manufacturer and is determined on a few factors including BMS design for lifepo4 and you will see lead acid batteries vary in C rate, some say 100Ah but at 0.01c rate)
@@DCGUY I agree with amham48. It is true that the C rate concept is a capacity time relationship where 1 hour = a 1C rating. Other rates are multiples or divisions of this. The formula is capacity * Crate = Current. So 50AH * .2C = 10Amps. So this battery was discharged at a 0.4C rate. So the result was especially impressive.
C rate is simply how long it will take a battery to fully charge or discharge at a certain current draw. A 50Ah battery discharged at a 1C rate will take 1 hour to discharge. 2C it would take 30 minutes. The Amp hour rating of the battery simply defines how long a battery will last at any given current draw. C rate doesn't change based on a batteries capacity it simply defines how long it will power something. So if we do a 0.2C discharge test on a battery (20 Amps) we are drawing 20 amps per hour from the battery and the Ah rate dictates how long it will take to drain. 100Ah = 5 hours 50Ah 2.5 hours 200Ah 10 hours etc.
Hi, I do have a question, though. I plan on replacing my Pb-batteries with two of these (serial, 24 V), can I possibly use the old charger for them? I´ve read that they are kind of "plug-and-play-"replacements. Is that true, in your oppinion? Thank you!
Technically, you can certainly continue using your existing charger, especially if the charger can deliver between 28-28.6v Bulk/Absorb and 27v Float. If not, while you can use it, it's not recommended for longer-term use as you won't receive the full potential of the Lifepo4 Battery capacity which generally requires a different charge algorithm than FLA or GEL batteries. If you do buy 2 of these 12V batteries, it is recommended to charge each battery individually using a 12v charger then allow them to rest for a few hours before connecting into series. Doing so will help keep the batteries balanced.
Thanks for the video! I was going to test one of those! Now i wont even try! Have you seen those wires? Thickness, ... thats unsecure and have very low quality! Like everyone says, chinese only copies and make bad quality products! 😂 never buy chinese products!
Thanks for the amazing video!!
Glad you liked it!
Nice video, thanks. Amazing just how much wasted space there seems to be inside the casing.
Thanks for watching and taking time to comment, it's appreciated

Thanks for your continued support 👍
I believe the aliexpress CAO MM battery store's "BPNN" 50 ah Lithium battery might be the exact same for a great price.
Take care
Cheers, I will check that out. Thanks
Thanks for the review and thorough tear down. Did you state 0.2C discharge...that would be 10A for a 50Ah battery and not 20A or am I mistaken?
