*No Hype* BEST DEAL I've Seen on 12V 100Ah: Siekon 12.8V 100Ah Classic 

Redodo formerly known as Zooms is made by the Enjoybot company. They make Ampere Time, Chins, Enjoybot, and the Redodo brands. So it wouldn't surprise me if they didn't make the battery in this video.

There's one brand on eBay right now for $179.00.

Thanks for the heads-up! I'll check in them!

You'd want to know if the 2 batteries are connected in series (2 x 24V = 55Ah @ 48V system), or in parallel (2 x 55Ah = 110Ah @ 24V) to ensure you match the system voltage correctly. But generally, yes - you should be able to find LFP batteries of a higher Ah rating and that should net you more distance on a single charge. Typically with Gel and SLA, you're not able to use the full rated Ah capacity anyway since they often limit you to between 50-75% discharge to protect the battery. So technically, even if you found an equivalent Ah capacity in LFP chemistry, you'd get more usable capacity/range just on the chemistry change alone.

@@ReeWrayOutdoors Thank you for your reply. I misspoke though. They are 12V 55ah batts in series to get a total of 24V. Would batteries of higher amps still be able to use the same charger? Would it just take longer to charge?

I have the same setup as you do as I'm newly paralyzed. I also have a good solar setup on my rv. A good charger is the victron 30 amp charger which you can control the charge rate with your phone once you get your lithium batteries set up

@@bobtedeman5975 Yes, greater amp-hour capacity means longer to charge. Do note, however, that a charger for lead acid chemistry may not fully charge the LiFePO4 chemistry. LiFePO4 would like to be charged to at least 14.2v and no more than 14.6v (double that for a 24v system). If your charger only reaches 14.0v it might reach full charge, but will take a very long time. One very nice thing about LiFePO4 chemistry, is unlike lead the battery will not be damaged if it is used at low states of charge and/or if it is never fully charged. One not so nice thing about LiFePO4 - if you overload lead the voltage will drop but it will keep supplying power. With LiFePO4 the battery has a built-in battery management system (BMS) to protect and monitor the individual cells in the battery. This BMS will prevent overloading the battery by shutting off the output after a short time. I don't know about the demands of your powerchair. Does it have a main battery fuse? If so, a battery rated to provide at least as much as that fuse should, I expect, work fine for you. (My experience is with computer UPS systems. They might use a pair of 12v lead batteries in series with 7ah, 9ah, or 12ah. LiFePO4 will usually fail to provide enough power for the UPS to support its rated load because LiFePO4 cannot be overloaded like lead.) In your 24v application, I think you would be most happy if you use a 24v battery instead of two 12v in series. A single battery has a single BMS built in to coordinate all 8 cells. Two in series will always be at a disadvantage.

absolutely. You just want to take into account the battery's (or battery system) max rated continuous discharge rate, which is limited by the BMS. If you regularly exceed that, you'll experience disconnects as the BMS turns-off discharge to protect the battery internals.

@mrhalfstep I double check the link n but definitely not a scam. They're probably out of stock at the moment and sometimes these Amazon links revert to a general landing page for their store when that happens. But thanks for letting me know so I can look into it.

@@ReeWrayOutdoors Another reviewer just posted a new link that shows it as a preorder on their website. Completely different from yesterday. Maybe my negative post on every YT channel that got these for free "to review" prompted them to get on the ball.
