Re: Is RoyPow a fake company??
As long as RoyPow keeps faking it and "making it", it seems like things will be ok as dealers will hold them to account.
I worry if there is a major incident with their packs, such as overheating, fire, explosion, etc that when insurance and lawyers get involved...RoyPow would just disappear. |

I agree 100%. That is/was my only concern with them. My dealer is a nice brick and mortar shop, and they are really great, but I know full well if my battery has an issue, it does not get fixed in-house. Not sure if they will give me another in the mean time or not (guessing not), but hopefully I don't have to find out. That is the only thing about lithium that bothers me. My other option would be to take it apart myself, which at some point I may do anyways once the warranty is over - just to put in a little beefier BMS. |

I think RoyPow is "real" in the same way that so many "companies" are these days (Anker, RAVpower, etc...). It's just marketing, a website and a logo really. Providing service and having dealers is a new foray, though, and one I'm not sure they've really got a good handle on. A few forum members have had issues with packs and the dealers have taken care of them, though in some cases it took some time IIRC. There are probably some cases where that didn't happen though, but at least there is some kind of dealer network / warranty there. I know the dealer I purchased mine from had sold a number of them before I got mine (and that was a year ago) and all his customers were thrilled with them at that time and he had not had any come back in. Not sure what his experience has been with them since then though. I looked into building one using Leaf cells but the fire hazard potential and having to go with used, years-old cells didn't sit well with me so I opted for RoyPow. In that case it was zero support -vs- possible support the way I looked at it. |

All these companies are doing is enclosing everything in a case and wiring up the BMS. Definitely not rocket science. Cheers Pat. |

Re: Is RoyPow a fake company??
Not sure I agree that good Lithium cells are "readily available off the shelf" for users. Let me know where they are if you can. I'm using Leaf cells because they were all I could easily find. That market is going down hill quickly IMO as the Leaf is not very popular and they are hard on batteries so if you get a used pack, it is likely nowhere near as good as new cells.

Re: Is RoyPow a fake company??
@Volt_Ampare,
They’re available but they’re prohibitively expensive in small quantities. If purchasing in quantity, any company that wants to start selling cart batteries will have access to good, high current output cells if they are prepared to pay a premium for them. That would push the final cost up but you get what you pay for. The idea that lithium cells will drop in price is a misconception. The cost of getting the raw materials out of the ground that go into the lithium cells are what pushes the price up, not the manufacturing process. And that price won’t be dropping any time soon. Lithium used to be used as a sanitiser in heated spa pools. It was a very good sanitiser. I haven’t been able to purchase lithium sanitiser for about 4 years now as all the lithium that is being obtained is being diverted into batteries. P.S. I also use Leaf cells, Gen1. My modules were down to 40aH when I got them compared to 66aH when new, so I agree with you that used Leaf cells are no longer a viable option. I don’t need a great range so it’s okay for me now. Cheers Pat. |

Re: Is RoyPow a fake company??
Lithium cells have come way down in price over the past decade. I have been using them for RC flying since around 2005 and price has dropped by about 4X at the same time the C rating has gone up by at least 10X. The cells that I would want to use in golf carts (like Leaf, Volt, Tesla) are not available to us users. Sure a big company can buy them but not us. Liability is a big issue in this market. The drop in cells are not the same stuff. Sure they are safer but they are also not as good IMO. You don't see that chemistry in many EV's out there.

If you want a credible supplier of lithium, go to Plowman's Carts. https://www.plowmanscarts.com/carts....cle=1614706381
He carries Allied and will order you Trojan Lithium. |

Re: Is RoyPow a fake company??
@Volt_Ampare,
Most of the high capacity cells that are available to “us” are LiFePo4, definitely not as good as LiPo cells, but they are much more stable and hence safer for the end user. Like you, I would much rather have high quality LiPo cells, smaller, lighter and higher discharge rate. Considering the higher risk of fire, I can understand why they aren’t readily available to the end user. Most LiPo batteries available to the end user are low capacity ones to minimise fire risk. An exploding 100aH cell will do much more damage than a 3aH one. The cost of lithium cells hasn’t really dropped much in the last 3 years and the C rate compared to size and weight hasn’t really gone up that much either in the same period. Maybe there was a significant drop in price early on but it seems to have plateaued now. @WC53, Most (all?) EV batteries are LiPo, which have a higher energy density and a higher discharge rate than LiFePo4, which is what most cart batteries are made up from. As for impact rating, that’s governed by the housing they are in. A ruptured high capacity LiPo cell is not something you want to be near. Cheers Pat. |
