RC Car Battery Guide: LiPo Packs, Plugs & Chargers
Short answer: Most of the bashers covered here (Omni-Terminator, Storm Breaker, ROG1) take a 2S–3S LiPo with an XT60 plug and come with a 3S 2200mAh pack. The 1/8 Dragon Scale Knight takes up to 6S on XT90 with 30–50C packs and no battery included. The TK07 and JK07 Pro crawlers run up to 4S. Match the plug, the size and your ESC's cell rating.

Battery chart: every model
Never use a pack above a model's maker-rated cell count. Where a figure is not confirmed here, the chart says so rather than guessing.
| Model | Max LiPo (maker) | Plug | Stock pack | Bay / pack size | Notes |
|---|---|---|---|---|---|
| Omni-Terminator Carbon (RZ001B-C) | 3S (60A ESC, 2–3S) | XT60 | 3S 2200mAh, 23×35×108 mm (RE032) | Small bay about 110×36×30 mm; larger bay about 140×30×45 mm with the tray kit (retailer data). The maker states its 3S 4400 (34.5×44×108.5 mm) fits without modification. | 4S only with a 4S-rated ESC: see the motor and ESC guide |
| Omni-Terminator Metal (RZ001G-A) | 3S (45A ESC, 2–3S) | XT60 | 3S 2200mAh | Bay sizes above are retailer figures; measure yours | |
| Storm Breaker (SBK10) | 3S (2–3S) | XT60 | 3S 2200mAh 35C | Small bay about 110×36×30 mm; a larger tray is included for bigger 3S packs (measure it) | |
| ROG1 (1/14) | 3S (45A ESC, 2–3S) | XT60 | 3S 2200mAh (some retailers sell a 2S 3000 option) | Confirm in your manual and measure the bay | 2S is milder for beginners |
| Dragon Scale Knight (DSK, 1/8) | 6S (180A ESC, 2–6S) | XT90 | None included | Bays 158×44 mm and 140×48 mm (maker) | Maker limit: 30C–50C packs (60C peak maximum) |
| TK07 (1/7 crawler) | 4S brushless (140A, 2–4S) | XT60 (maker) | None included | Battery space 164×49 mm (maker) | The brushed version is listed differently: confirm in your manual |
| JK07 Pro (1/7 crawler) | 4S (140A, 2–4S) | Confirm in your manual | None included | Confirm in your manual | The plain JK07 (non-Pro) differs: confirm in your manual |

LiPo basics in two minutes
- Cells (S): 2S 7.4 V, 3S 11.1 V, 4S 14.8 V, 6S 22.2 V nominal. Your ESC's rating sets the maximum.
- mAh: capacity, which means run time.
- C-rating: how hard the pack can safely discharge. Higher is not always better: the DSK's maker limits packs to 30–50C.
- Plugs: XT60 handles less current than XT90 and they are not interchangeable without adapters; adapters add resistance.
- Case: hard cases protect better than soft packs in a basher.
Fake and knock-off LiPos
Warning: fake LiPos. Be suspicious of packs claiming very high capacity and C-ratings in a small, light case, packs with no brand or maker information, and prices far below the brand's own. Buy from the brand's official store or an authorized seller. A pack that is lighter than comparable packs of the same capacity is a red flag.
Omni-Terminator and Storm Breaker
The stock pack is a 3S 2200mAh, about 23×35×108 mm, with an XT60 plug. Bigger 3S packs fit with the tray kit or with the ESC moved; see ESC relocation. Shorty packs (short and wide) and stick packs (long and thin) suit different bays, so check length, width and height against your bay. Four-cell packs only work with a 4S-rated ESC: the stock ESCs on the Omni-Terminator, Storm Breaker and ROG1 are rated 2–3S.
Battery weight and bigger tires both affect handling: see the tires and body guide. Spare packs are part of the field spares kit.
ROG1 (1/14)
The ROG1's ESC is rated 2–3S and the stock pack is a 3S 2200mAh. Some retailers also sell a 2S 3000 option, which is milder for beginners. Stick to stock-size packs until you have measured the bay.
Dragon Scale Knight (1/8)
The DSK takes up to 6S on an XT90 plug, with no battery included. The maker specifies 30C–50C packs (60C peak maximum), so very high-C packs are not recommended. The bays are 158×44 mm and 140×48 mm. Do not buy a 100C+ car pack for it just because it fits.
1/7 crawlers: TK07, JK07 Pro and MK-07
The TK07 brushless and the JK07 Pro are listed at up to 4S (140A, 2–4S). The TK07's battery space is 164×49 mm and its plug is XT60. None of the crawlers ships with a battery. For the MK-07, the plug, bay size and maximum cell count are not confirmed here, so read the maker's manual before buying a pack.
Shipping LiPos: check before you buy
LiPos are dangerous goods. AliExpress and some other marketplaces only ship them to some countries and from some warehouses. Check the shipping section for your country before adding a pack to your cart. Local warehouses usually ship faster and avoid air-freight battery limits. If a pack will not ship to you, buy locally: the chart above still tells you what fits.
Charging safety
Use a LiPo balance charger set to the right cell count. Charge at 1C unless the maker allows more. Never charge unattended, never charge a puffed or damaged pack, and charge in a LiPo-safe bag or box on a non-flammable surface. Let packs cool after a run. Never charge above 4.2 V per cell, and set your ESC's low-voltage cutoff so packs are not run below about 3.2–3.3 V per cell under load.
Storage and disposal
Store packs at about 3.8 V per cell if you will not run them for more than a few days, using your charger's storage mode. Keep them in a LiPo bag or ammo-style box at room temperature, away from sunlight and car interiors. Stop using swollen or damaged packs, discharge them safely and recycle them at a battery recycling point, following local rules.

FAQ
What battery comes with the Omni-Terminator, and what size is it?
A 3S 2200mAh LiPo, about 23×35×108 mm, with an XT60 plug.
What is the biggest battery that fits the Omni-Terminator?
Retailer data lists a larger bay of about 140×30×45 mm with the tray kit, and the maker says its 3S 4400 pack fits without modification. Bigger packs need the tray kit or the ESC moved. Measure first.
Can I run a 4S battery in my car?
Only if the ESC is rated for 4S. The Omni-Terminator, Storm Breaker and ROG1 ESCs are rated 2–3S. The DSK goes up to 6S, and the TK07 and JK07 Pro to 4S.
What battery connector do these cars use (XT60 or XT90)?
XT60 on the 1/10 and 1/14 models and the TK07; XT90 on the 1/8 Dragon Scale Knight. Check the plug for the JK07 Pro and MK-07.
Which battery for the Dragon Scale Knight, and why the 50C limit?
The maker specifies 30C–50C packs with a 60C peak maximum, so very high-C packs are not recommended. Use an XT90 pack that stays within that limit.
Do the TK07, JK07 Pro and MK-07 come with a battery?
No, none of them ships with a battery.
2S or 3S for the ROG1?
3S is stock; 2S is milder for beginners and some retailers sell a 2S 3000 option.
How long does a LiPo take to charge?
A proper balance charger at 1C charges an empty pack in about an hour. A small included USB charger can take several hours for bigger packs.
Are third-party or brand-name batteries safe in my car?
Yes, if the cell count, plug, size and C-rating match the maker's spec.
How can I tell if a LiPo is fake?
Be wary of very high capacity or C-ratings in a small, light case, no maker information and prices far below the brand's own. Buy from official or authorized sellers.
