Parallel Battery Harness vs Parallel Switch: which one is better? 

what is a mangosteen? jewish mango? joking aside, yes you can connect two batteries with the same voltage together.

Good question, instantaneous current forward or reverse is up to 3X the nominal current of 30A

This is what i have 2 of the exact same batterys i was gonna join from terminals but if a simple y harness will do thats what ill do but do u think i should just run one charger into both or charge them separately and just always check voltage??

@@whitefeatherslinger8194 I run one charger through the main charging port, it charges both batteries to 75% and stops. I charge it again and the main battery goes up to 41volts and second battery goes to 39volts. I then charge it individually. I think it has to do with the BMS on both battery packs.

@@whitefeatherslinger8194 I run through one charging port, when charge turns green the volt for both is around 40 and finish them off individually.

Yes we do it’s our manual solid state switch

Yes I think you can

Thank you for your detailed thoughts on this. You came out strong and we respect that. But it’s full of assumptions and a misunderstanding of the what we are trying to do. If one of those batteries has the right cells and BMS that can handle your motor power, one of those batteries is all that you need, you don’t need 2 or 10 of them. Secondly our whole point is that with the switch you do not need to always ensure your batteries are charged to the same voltage. It’s a hassle. Just plug into the switch and switch take care of it. That’s the whole point.

@Falcon Pev | Pab Pmd Escooter Ebike Shop Singapore sorry was using the scooter pictured in the picture for example which is a 2wd scooter and would typically take beyond the small batteries nominal output, motors and electronics should be matched to the ride as a setup that pulls more amps vs the bms is able to produce is a hazard in itself, imo. If the only convenience of the switch is the ability to charge and use both batteries with different charges... the advantage is not that great vs the advantages provided by parallel*. (*unless used with a small 500w scooter which doesn't have much for power req and you just want easily modular add/remove range) Parallel =more amps and slower drain across the board and thus increased battery life and longevity. Charge once and match voltage... setup and forget. The Switch, a person could disconnect and connect as they please, without worrying about battery equalization... but parallel would give more speed/acceleration as you'd have the combined output amps of both battery which would hold you in higher voltage longer, with the inconvenience of matching voltages before using or leaving in place. The hassle of connecting together isn't that great for casual use and is none existant for anyone planning on plugging in and using both at the same time. But you should be able to agree on the fact parallel will make the batteries health last longer as it would be a slower drain across the board vs the switch. On final note...you could also reduce charge time with parallel as a fast charger like 4amp or 5amp would be much better suited to charging both batteries vs a fast charger doing one at a time via switch... using a fast charger sparingly is recommended for single 52v 20ah battery, but could be used more frequently in a setup with a 52v 20ah and 52v 10ah second battery in parallel due to the increased charge rate capacity of parallel.

Not with ninebot

Not possible

no flashing needed. Just the solid state switch is sufficient

@@FalconpevSg Thank you very much, I wasn't game to buy a bigger battery just yet, Just bought basicly the same size and amp battery to have as the external, If that doesnt do much i will get a little bigger amp battery next time. Let you know how it goes when it all turns up. Its just a ZiaomiM365

You will need the parallel cable like in the video. Then just plugged the parallel cable into the controllers and to each battery and you are good to go. Just make certain to fully charge both batteries before taking your bike out for a ride.

@dariusbendasiuk5678 all time

With two chargers

We can show you how to do the connections when you purchase the switch
