Oset 24 r battery upgrade - Help!

[andytmsn]

Hi, I've purchased an Oset 24 R but the Li-pol batteries that came with it give poor performance. It came with 2 x 22V 12000mAh batteries and they're connected in series to give 44V and 12ah. The Oset comes with a 1400W motor and 130A controller. Mine must've had the batteries upgraded from the SLA batteries, the newer versions come with a 48V 20ah Lithium-ion battery. I want to get the most out of the bike and was thinking of making the following battery; 10p14s - 30ah - 51.8V battery made from Samsung Q30 cells that are 3000mAh and nominal 3.6V. I'm wondering firstly, will making the battery 51.8V be ok for the motor? And 10 of these cells in parallel will give a continuous discharge rating of 150A, will that be ok for this bike? It struggles to climb hills as is, I want it to have all the power it needs without putting to much strain on the battery pack. Any thoughts on a possible better battery pack welcome

Hey I looked into making up a battery for a friends osset about a year ago but it never eventuated. The motor won't really care what voltage your battery is, it's the controller you need to worry about. I don't know what max voltage it can handle, but it shouldn't be too hard to find out, if in doubt just put in a similar V battery. Upping the voltage won't increase low range performance, but past 1/2 top speed it will be noticeable, and your top speed will be higher. If you're looking for low speed torque, that's more amps you need. A new battery will help, but only if the old one couldn't put out that amount of current otherwise you'll need a bigger controller or lower gearing.
The 30qs in 10p will do that peak amp draw comfortably. It's a good choice of cell, just check the dimensions to make sure that size will physically fit in the space provided.
You have to realize it's not the battery or motor that determines power flow (usually) it's the controller that regulates the amps, so you'll only see 130a Max for a very brief period ( at full throttle and near stationary) you'll need a beefy bms if your not re-using the original. The rest of the time the current draw should be substantially lower.

Its a great upgrade! And lasts foever

I'd be interested in an upgraded battery for my Oset 24.0.
