Not only would the 160 not fit in half of the battery compartment - meaning I would have to cut out the plastic divider and reroute some of my wiring - it's also nearly 50 lbs. heavier. But, if I could have found a 160 version in stock, I probably would have gone with it. I just got tired of waiting and couldn't get a definitive answer on when the 160s would be available. |

Re: Took the RoyPow plunge
It's worth noting that the 160ah uses 32 75ah cells (or 80ah?) in a 16s2p arrangement (link below I think are the cells they are using in this pack - EVE energy doesn't list a 80ah cell) -vs- 16 105ah cells in a 16s1p arrangement.
Twice as many cells, connections, BMS sub circuits etc.. could (could - not should) increase failure points. At the same time, if you double the listed 30 second permissible current draw of the 75ah cells (since there are 2 in parallel for each 3.2v) - which I think would be accurate? - it is greater than that of a single 105ah cell. Someone else (Sergio?) can chime in here on this... Link is mostly Chinese for the 75ah cell, but the bottom chart in the PDF is the same data I posted earlier for the 105ah cell. http://www.dcmax.com.tw/LF75(3.2V75Ah).pdf |

Re: Took the RoyPow plunge
Congrats! I've gone back and forth between this pack and some custom packs from AliExpress. You answered one of my biggest questions - is it as simple as connecting positive and negative and being done!?
I have factory everything so far, but think the next thing is to grab the alltrax that everyone seems to love - so at least i know what I haven't messed up yet from factory! ha edit: Wait, what about your charger? Are you using the stock delta FLA charger with this? The pack I'm looking at will come with it's own charger, but that means I'd need to swap charger receptacles and all this mess... and wonder what sort of safety measures are tied to the OEM charger receptacle, like disabling the key start. |

One dealer I spoke with usually makes the charger an onboard charger and changes the receptacle to take a regular extension cord. I thought about doing that but I don't want to subject my charger to all of the bumps, vibrations, heat, etc. |

Re: Took the RoyPow plunge
Have you had a chance to test how far it will go on a charge?

Re: Took the RoyPow plunge
I would also like to know how far you get on a charge.... compared to previous FLA batteries. I know that isn't apples to apples when you have to consider that FLA batteries where probably older and this a new pack, but I'm still curious.

That being said, I charged it on Sunday, and have driven it 6 times - that's 6 miles on hilly terrain at wide open throttle. On their SOC meter, there are 10 lights showing a full charge and there are still 7 of them lit, and my volt gauge reads 53.1 volts... |

Re: Took the RoyPow plunge
You got enough room to put a second one in there and use a high amp switch to go back and forth.
Guessing it wasn't cheap, but for a drop in solution that looks like one of the best setups I've seen. |

Re: Took the RoyPow plunge
I read where these Rowpow packs are rated for 3500 cycles.....isn't FLA batteries rated for about 500 cycles? Is that possible that these will last 7 times as long? Or am I missing something? My batteries are little more 4 years old and I am seeing some degradation and think I will probably have to replace next year or so. So does that mean that if I buy this pack, that it will last me 7 times as long as FLA's? Instead of 4 years (or so), I'll get 28 years? Hard for me to believe --- or my math isn't right (which is probably the case) :(

Re: Took the RoyPow plunge
# cycles is only one rating. I would count on 10 years of service if you take care of them. FLA batteries usually start to fail at 5 years - if you take care of them. Some get more some less.
