I'm doing this upgrade right now on my son's Oset 12,5r...from 2x SLA lead acid 12v 10Ah batteries (in series, so 24v total) to 2x LiPo 6s 7000Ah (in parallel, so 14Ah in total). I will use exactly your configuration with the harness (to use also SLA batteries if needed), XT90 connectors and 10awg wire. Thanks a lot for your guide.
Awesome, he will enjoy the additional run time and power delivery!
Great Video!!
Thanks Real Estate!
love your vide
Thanks for the support!
Nice! Where in Nc?
Nice video! Is it possible to use the original lead acid charger for the LiPO batteries? If not, which charger do you use?
Thanks! No it’s not possible to use the original charger. I use a maxamps 24v 47A power supply (dual 120v inputs) connected to a ISDT T6 smart charger. You need a smart charger to balance charging across LiOn cells. The smart charger however can be used to charge multiple types of batteries including SLA.
I am doing an ebike build on a full size bike right now but I would like to use this kind of set up for a future pit bike build. Do you think it is possible to put all of the balance leads into a full size bms and charge/monitor all of the batteries that way? Also if you have a programmable controller you shouldn't have to use low voltage alarms and just let the controller take care of the cut off?
Yes all this is possible. The oem controller was for Lead acid batteries only. Oset now makes a Lithium battery powered one just like this model.
@@MTBPlanB oh okay makes sense why you didn't go that route, also somewhat unnecessary I suppose but the peace of mind would be nice.
Looking to do this on my kids bike that needs a battery replacement! What model lipo batteries did you use and how is the upgrade holding up? Thanks!
I used two of these in series hobbyking.com/en_us/turnigy-high-capacity-battery-20000mah-6s-12c-drone-lipo-pack-xt90.html. Batteries still going strong. I also use two low voltage alarms to notify me before over-discharging.
@@MTBPlanB Hi there, I just bought a used oset 20.0 and the acid battery pack is dead, so I'm looking for a Lipo alternative. What charger do you use for those batteries? How many hours for a complete charge of both batteries? Great video!
Javier Villanueva I use the ISDT T8 Balance charger with Maxamps 24v power supply. I charge at 20amps and it takes about 35 minutes.
@@MTBPlanB does it charge both at the same time?
Javier Villanueva I don’t but You can charge both at the same time. It helps to have a different 20amp circuit to plug the supply for faster charging.
I am trying to upgrade the batteries on my kids Set 12.5R any recommendations?
what's the difference between those two batteries? im tryin to build on my own e scooter but kinda hard to choose which battery i should pick . can you please explain to me sir?
LiON batteries have a larger energy density, better charge/discharge properties, Lighter than lead acid/agm and will perform better if properly managed,
I have an old Zero MX w dead batteries. I wonder how many of them Lipos I would need to just get like 2 hour of riding in? I think it’s pulls 18k watts max.i would like to ride it like a trials bike. The Original pack probably weighed 45 pounds, LiPos.
It’s probably the 1400W motor. If it’s a 48v system and assuming about 35% average throttle over 2hrs, likely a 20Ah battery pack would do the trick.
@@MTBPlanB 🙏 Thanks
No problem!
hi. i went to the dealership and they said i would need new looms and a new controller(of course they would :-) ). Have you run this through the standard SLA controller that came with the bike? Looking to upgrade an Oset 16R 36V with something like Li-ion Battery Volt Rechargeable For E-bike 36v 20ah 500w 20000mah. Any help appreciated....
Should be able to use existing controller (as long as you use like for like battery) but you would need new looms if you wanted to charge thru existing port and have the charge indicator work properly. I just charged externally and used low voltage alarms on the balance port of the batteries.
@@MTBPlanB thank you and thanks for the great video. Sorry for further questions.... so the voltage is the important part, the ampage just means longer use (so more amps better? i have 3 12v 10aH in series currently. happy to charge separately etc. thank you in advance.... would be great to get the bike used again :-)
Yes exactly. More Amp hours means longer riding time. The electric motor has a peak wattage rating and will pull max current at the specified input voltage. You currently have 10amp hours available. Find your peak wattage on the motor and using equation Power = Voltage * Current you can figure out peak current pull and workout how long 10AH would actually last at full throttle.
@@MTBPlanB top man, thank you!
Would this be suitable for the 36v setup In the 16.0R ?
No but a couple of 5S batteries in series would do the trick for 36v. Or you could purchase three 12v lifepo4 batteries.
@@MTBPlanB Exellent thanks for the help. I’ll give that a bash 👍🏻
Good idea,what bike is this bro 🤔
Junior Ellis Oset 20R trials motorcycle.
How many volts are the lipos ?
6 cell 22.2v each, wired in series for 44.4v.
Hi. What spec are those lipos
I’m using two 6s 22v 20AH in series.
I’m using two 6s 22v 20AH in series.
Also, what seat is that? Thanks
That was an Oset option when purchased.
how long can u ride?
A little over two hours on the LIPO setup vs 55 minutes on SLA,
Hello!
Did you felt a change in acceleration / top speed?
charlesobiwan I doubt it but but I didn’t do any initial tests with SLA batteries. You get more consistent power delivery over a longer ride with the Lithium batteries and increased Amp hours, which was my intention.
Depending on how much lighter the pack is, and if it has the same power output, you could get better acceleration because of the reduced mass. F=ma.
$200 per lipo pack right now on HobbyKing. Ouch!
They are pricey but have held up amazingly!
