always curious to see inside those Lithium batteries. thanks.

No BMS, just a balancer board, no wonder why it failed.

Yes an active balancer, they didnt put bms as it has over current discharge protection, it will kick in during hard starting events as starter will drawn out too much current.

Well, I watched the video looking for certain explanations and did not get them, just enough to actually be somewhat dangerous at least for the battery and some miss info. 1 Lithium batteries are 1 of two types, Ion or Phosphate. Not both. Professionals call the phosphate type LIPO and use the ION (very different battery) for only those. This one is a phosphate type according to the info I got from the SSB site ( but part numbers were not included so just slightly conceivable it could be ION, not likely because of the differences in voltages). As a phosphate battery it MUST have a disconnect for too high of voltage or too low of voltage, and too high of temps or too low. Not sure, could be dangerous if too high, definitely ruins the battery if it tries to be charged when the temps too low. This BMS has none of that. The voltages just different enough with the ION battery to make a huge safety impact. BMS/s for both type will end up with a damaged battery if voltages go too low (no disconnect). EXTREMELY important for a Motorcycle battery, because all you would have to do is leave the ignition on and battery is ruined after a certain amount of time ! Danterous ? Well, if you puncture either type of battery the fire that results is dangerous, so you must have protection for that. The motorcycle would be toast !

Great.. thanks! im not a teacher.. i was just pulling a battery apart. thanks for the reply though.

Not a good battery. No BMS, just a balance board. Nothing to prevent over discharge or over charging. Also missing temperature sensor to prevent overheating. I wouldn’t want that in my bike. It’s likely to leave you stranded in the middle of nowhere. The problem with this technology is it’s very difficult to figure out who makes a good battery with a well designed BMS that can handle the amperage draw when starting the bike. Clearly the batteries shown hear have a very limited lifespan without a good BMS. It would be interesting to see an AntiGravity battery teardown. They get good reviews, but cost a small fortune.

Seems like these batteries should be a lot cheaper than they are. Nothing inside to justify the high prices they charge. Wonder if the packets can be purchased on there own for a more normal price.

It costs alot of money to develop then build a quality battery. Yes you can buy the individual 'packets' which are called cells, but you would probably be quiet supprised how much they cost, atleast for a quality part that will last and wont spontaniosly combust, then you have to hook them up to a charge controller... I reckon they are a steal

@@jackheinemann1994 and anti gravity lithium is around £300 its a lot of money and its only around 4ah. I can buy a 18v 5ah drill battery for peanuts I get what your saying but I'm really struggling to justify the cost.. I've been picking up thrown away vape batteries and I've got over 30 now. Made my own battery packs I've got a 7.4v 4500ma 7.4v 3300ma 14.8v 1100ma and 11.1v 550mah and still have a few cells left over. And all for free.

Am I missing something. What does the circuit board do? The case terminals seem to connected directly to the cells, presumably in Series. So if the circuit board is a battery protection controller how does it stop the cells from over charging or over discharging? I can't see any relay or mosfets to shutdown the power output, if there's a problem?

It is not a battery protection controller. It is look like a cell equalizer circuit. Lithium batteries must be charged separately each cell in order the battery bank charge to be correct. The circuit not only charging the batteries but also equalizes the voltage across each cell so all cells will have the same voltage, thus same charge.

This battery is not safe it's will catch fire easily

Interesting, I pulled my SSB apart a few years ago after it died which I presume was due to faulty BMS, mine did not have all that caulking in it

wouldn't it need to have a BMS for it to go faulty?
